    Ancient Calendar, Recently Discovered, May Document a Long-Ago Disaster

    The markings on a pillar in southern Turkey are more than decorations on the stone, a researcher at the University of Edinburgh says. They may memorialize a time when comet fragments struck Earth.A researcher at the University of Edinburgh has discovered what he believes is the earliest calendar of its kind at Gobekli Tepe, an archaeological excavation site in what is now southern Turkey that used to be an ancient complex of temple-like enclosures.The researcher, Martin Sweatman, a scientist at the University of Edinburgh, said in research published last month that V-shaped markings on the lunisolar calendar, which combines the movements of the moon and sun, recorded a major astronomical event that had a huge impact on Earth — making the ancient pillar part of an ancient version of a memorial.Dr. Sweatman said that the intricate carvings at Gobekli Tepe tell the story and document the date when fragments of a comet — which came from a meteor stream — hit Earth roughly 13,000 years ago. The comet strike, which the latest research has placed in the year 10,850 B.C., has long been a source of disagreement among academics and researchers.This is not the first time that Dr. Sweatman has been able to connect the impact of the comet to the site in Turkey, he said. In 2017, he linked the two in an academic paper in which he contended that the carvings at Gobekli Tepe were memorialized in the pillars, and that the site was used as a place to observe space.At the time, a group of excavators at Gobekli Tepe challenged those findings. Jens Notroff, an archaeologist who wrote the post on the excavators’ website, was not immediately convinced about the new findings and questioned whether the markings had a deeper meaning. He said on the social media platform X that there was an “an obsession with the idea that there *must* be a secret, a hidden code which needs to and can be decoded — while it’s really just about past humans living their lives.”Dr. Sweatman said the recent discovery that one of the pillars also depicts a lunisolar calendar — and thus marks the day of the impact — lined up with his prior research. “We can be very confident indeed that it’s a date,” he said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Netanyahu Vows ‘Severe’ Response to Deadly Rocket Attack Tied to Hezbollah

    Fears linger among Lebanese civilians after a strike killed 12 children and teenagers in the Israeli-controlled Golan Heights.Tensions were high on both sides of the Israeli-Lebanese border on Monday as Israeli leaders vowed to deliver a significant military blow against the armed group Hezbollah in response to a deadly rocket attack over the weekend.The attack on Saturday killed 12 children and teenagers in the Druse Arab village of Majdal Shams in the Israeli-controlled Golan Heights.Hezbollah, an Iran-backed militia that dominates southern Lebanon and that has been firing rockets into Israel for months, denied responsibility for the strike. But Israel and the United States blamed the group, saying it was Hezbollah’s rocket that had been fired from territory it controls.Israel’s prime minister, Benjamin Netanyahu, who visited the site of the attack on Monday, said, “Our response is coming, and it will be severe.” Local residents heckled Mr. Netanyahu, telling him they had no security and chanting, “Murderer! Murderer!” videos posted on social media showed.Mr. Netanyahu’s visit to Majdal Shams came the morning after Israeli cabinet ministers authorized him and Israel’s defense minister, Yoav Gallant, to determine the nature and timing of the military response. The strike and Israel’s expected counterattack have raised fears that nearly 10 months of armed conflict between Israel and Hezbollah could spiral into an all-out war.Hezbollah began firing rockets, antitank missiles and drones into Israel in solidarity with Hamas after that group, which is also backed by Iran, led the deadly Oct. 7 attack on southern Israel.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Israel’s Strike on Iran Highlights Its Ability to Evade Tehran’s Air Defenses

    The retaliatory attack damaged a defense system near Natanz, a city in central Iran that is critical to the country’s nuclear weapons program.An Israeli airstrike on Iran on Friday damaged an air defense system, according to Western and Iranian officials, in an attack calculated to deliver a message that Israel could bypass Iran’s defensive systems undetected and paralyze them.The strike damaged a defensive battery near Natanz, a city in central Iran that is critical to the country’s nuclear weapons program, according to two Western officials and two Iranian officials. The attack — and the revelation on Saturday of its target — was in retaliation for Iran’s strike in Israel last week after Israel bombed its embassy compound in Damascus. But it used a fraction of the firepower Tehran deployed in launching hundreds of drones and missiles at Israel.The strike on Friday was the latest salvo in a series of tit-for-tat attacks between the two countries this month that have heightened fears of a broader regional conflict. But the relatively limited scope of Israel’s strike and the muted response from Iranian officials seem to have eased tensions.Iran and Israel have conducted a yearslong shadow war, but the conflict intensified on April 1, when Israeli warplanes killed seven Iranian officials, including three senior commanders, at an Iranian diplomatic compound in Syria, which Israel asserts was used as a military site. Iran responded last week by firing a barrage of drones and cruise and ballistic missiles at Israel, almost all of which were shot down by Israel and its allies. But the strikes nevertheless rattled Israelis.That attack was Iran’s first-ever direct assault on Israeli soil, thrusting the countries’ clandestine warfare — long fought by land, air, sea and cyberspace — into open view. The Israeli government vowed to respond, even as world leaders and Western allies, including the United States, rushed to de-escalate the situation, urging Israel not to respond in a way that could lead to a regional war.A protest against Israel after Friday prayers in Tehran.Arash Khamooshi for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Turkey Restricts Exports to Israel in Protest of War in Gaza

    Turkey said on Tuesday that it would restrict exports to Israel until there is a cease-fire in Gaza, prompting threats of a tit-for-tat response from a government with which it has long had tense relations.President Recep Tayyip Erdogan of Turkey has defended Hamas and lashed out at Israel over the war in Gaza, accusing it of deliberately attacking civilians. But his government had until Tuesday stopped short of taking concrete economic measures against Israel over the conflict.Turkey’s Trade Ministry said it was imposing restrictions covering dozens of exports — including aluminum, steel products, cement and jet fuel — after Israel denied a Turkish government request to airdrop humanitarian aid to Gaza.“This decision will remain in place until Israel declares a cease-fire in Gaza and allows the flow of a sufficient amount of uninterrupted aid to the Gaza Strip,” the ministry said in a statement.The announcement drew an angry response from Israel’s foreign minister, who accused Mr. Erdogan of “sacrificing the economic interests” of Turkey’s people in the name of supporting Hamas.“Israel will not capitulate to violence and blackmail and will not overlook the unilateral violation of the trade agreements and will take parallel measures against Turkey that will harm the Turkish economy,” the minister, Israel Katz, said in a statement.Turkey’s exports to Israel were worth $5.4 billion in 2023, or 2.1 percent of its total exports, according to official data.Turkey has long had turbulent relations with Israel, though in recent years there had been some signs of a thaw: In 2022, Turkey welcomed Israel’s president to Ankara, the first visit by an Israeli head of state since 2008. Mr. Erdogan met with Prime Minister Benjamin Netanyahu of Israel for the first time last September.Less than a month after that meeting, Hamas led the Oct. 7 attack on Israel that set off the war in Gaza.Under Mr. Erdogan, Turkey has often hosted members of Hamas, some of whose leaders were in the country for meetings on Oct. 7. The Turkish leader has strongly criticized Israel’s bombardment of Gaza, putting him sharply at odds with his NATO allies.But the rising death toll and dire humanitarian crisis in Gaza have prompted increasing criticism from Israel’s allies over how the war is being conducted.President Biden threatened last week to condition future U.S. support for Israel on how it addresses his concerns about civilian casualties and the humanitarian crisis. This week, the foreign minister of France told French news media that imposing sanctions might be one way of putting more pressure on Israel to open humanitarian corridors to Gaza.Gabby Sobelman More

    State Dept. Tells Congress It Has Approved Sale of F-16 Jets to Turkey

    The department received documents on Friday signed by Turkey’s leader approving Sweden’s long-delayed entry into NATO. The alliance now awaits word from the lone holdout, Hungary.The State Department notified Congress on Friday that it had approved a $23 billion sale of F-16 fighter jets and related equipment to Turkey after the country’s leader signed documents to allow Sweden’s long-delayed entry into the North Atlantic Treaty Organization, department officials and the Pentagon said.Although Congress could move to formally block the sale, four senior lawmakers told the State Department on Friday evening that they would not object, after their aides reviewed the documents signed by President Recep Tayyip Erdogan of Turkey, U.S. officials said.Congressional officials had demanded to see the documents before signaling their approval of the sale, so the State Department asked Turkey to fly the documents to New York on Friday. The department had someone pick up the documents in New York and bring them to Washington by Friday evening to show the lawmakers.The department’s subsequent formal notification to Congress means the sale will almost certainly occur, satisfying Mr. Erdogan’s main condition for supporting Sweden’s accession to NATO and potentially helping bring to a close an episode that has strained relations between the United States and Turkey.Turkey was, along with Hungary, one of two NATO members withholding approval of Sweden’s entry into the alliance. Secretary of State Antony J. Blinken had undertaken intense diplomacy since last year, including meeting with Mr. Erdogan in Istanbul this month, to try to change the Turkish leader’s mind.Mr. Blinken discussed the issue with Mr. Erdogan in a visit to Turkey in February 2023, and said three times that Turkey would not get the F-16s if it refused to approve Sweden’s accession, a U.S. official said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    F.B.I. Raided Homes of Second Adams Aide and Ex-Turkish Airline Official

    On the same day the federal authorities raided the home of Mayor Eric Adams’s chief fund-raiser, they also searched the residences of two people with ties to Turkey.As F.B.I. agents searched the home of Mayor Eric Adams’s chief fund-raiser earlier this month for evidence his campaign conspired with Turkey, separate teams executed warrants at the residences of two others with ties to the mayor and that country, several people with knowledge of the matter said.In addition to the home of the fund-raiser, Brianna Suggs, investigators also searched the New Jersey houses of Rana Abbasova, an aide in Mr. Adams’s international affairs office, four of the people said, and Cenk Öcal, a former Turkish Airlines executive who served on his transition team, two people said.The coordinated raids were the first public sign of a broad corruption investigation into the mayor’s 2021 campaign. As part of the inquiry, the F.B.I. and federal prosecutors in Manhattan are examining whether the Turkish government conspired with Mr. Adams’s campaign to funnel foreign donations into campaign coffers and whether Mr. Adams pressured Fire Department officials to sign off on a new high-rise Turkish consulate despite safety concerns.Both Ms. Abbasova and Mr. Öcal have ties to Turkey. She was Mr. Adams’s longtime liaison to the Turkish community when he served as Brooklyn borough president; he was the general manager of the New York office of Turkish Airlines until early last year. Ms. Abbasova, Mr. Öcal, Ms. Suggs and Mr. Adams have not been accused of wrongdoing.The searches began early on the morning of Nov. 2, when a team of F.B.I. agents descended on the brick Fort Lee, N.J., townhouse of Ms. Abbasova, 41, who serves as the director of protocol in the Mayor’s Office for International Affairs. It was not clear what, if anything, they took from the home.A separate team of agents visited the New Jersey home of Mr. Öcal, a former flight attendant who, according to his LinkedIn page, rose to become a Turkish Airlines general manager, first in Sofia, Bulgaria, and then in New York. Mr. Öcal, according to a Turkish news report, was fired from the airline in early 2022 during a shake-up at the company.Ms. Abbasova and Mr. Öcal did not respond to messages seeking comment, and it could not immediately be determined whether they had hired lawyers.Evan Thies, a spokesman for Mr. Adams’s campaign, said, “Ms. Abbasova was not employed by or paid by the campaign.” Fabien Levy, a spokesman for City Hall, said in a statement that the mayor was cooperating with investigators. Mr. Adams has denied any wrongdoing and, through his attorney Boyd Johnson, noted that the campaign had proactively reported an unidentified individual to federal investigators for recently acting “improperly.”On Thursday, two people briefed on the matter confirmed earlier reporting in The New York Post that the individual was Ms. Abbasova. Mr. Thies declined to elaborate on the conduct in question.Representatives for the F.B.I. and the United States Attorney’s Office for the Southern District of New York declined to comment.The raids occurred on the same morning that agents searched Ms. Suggs’s Brooklyn home and left with three iPhones, two laptop computers and other evidence, records show.The searches came as federal officials were examining potential malfeasance in Mr. Adams’s 2021 campaign, an inquiry so far-reaching that, last Monday, agents approached Mr. Adams on the street outside of an event in Manhattan, asked his security detail to step aside, and climbed into his car alongside him. Pursuant to a court-authorized warrant, they seized his electronic devices.Less than three weeks ago, Ms. Abbasova, who earns $81,000 in her current post, stood just behind Mr. Adams’s right shoulder during a flag-raising ceremony at Bowling Green to mark the 100th anniversary of the Turkish republic. The Turkish consul general and U.S. ambassador were in attendance as Mr. Adams spoke of his affection for the country.“I‘m probably the only mayor in the history of this city that has not only visited Turkey — Türkiye — once, but I think I’m on my sixth or seventh visit to Türkiye,” Mr. Adams said.In a 2017 interview with a pro-government Turkish news outlet, Mr. Adams said he preferred to fly Turkish Airlines on international trips, in part because the airline accommodated his dietary needs as a vegan. “Turkish Airlines is my way of flying,” he told the newspaper.At the flag raising, Ms. Abbasova handed a folder containing an honorary citation to the mayor, who awarded it to a local Turkish community member. Then she distributed small red Turkish flags to some children.She began working for Mr. Adams as a volunteer in his first term as borough president, as he tried to make inroads to the Turkish and Azerbaijani communities in Brooklyn. She was given an office to use at Borough Hall, a former aide said.She has been on his government staff since at least 2018, when city records indicate she joined the borough president’s office as a “community coordinator,” earning $50,000 a year. Her title in 2021 was “assistant to the compliance unit,” according to a list provided to Mr. Adams’s successor as borough president, Antonio Reynoso, Kristina Naplatarski, a spokeswoman for Mr. Reynoso, said.While there, Ms. Abbasova managed relationships between Mr. Adams and “stakeholders” from the Middle East and Central Asia, “organized Turkic heritage events,” “assisted with sister cities agreements,” and “worked with embassies and consulates to build relationships,” according to her profile on the website of the Mayor’s Office for International Affairs.In 2015, several years before she officially joined his staff, Ms. Abbasova traveled to Turkey with Mr. Adams on a trip sponsored by the Turkish consulate and the World Tourism Forum Institute, an organization whose mission is to boost global tourism.The current borough president’s office does not have a position like the one held by Ms. Abbasova, according to Ms. Naplatarski.“We do not,” she said, “nor have we ever under this administration.”Susan Beachy More

    F.B.I. Examining Whether Adams Cleared Red Tape for Turkish Government

    After winning the 2021 Democratic mayoral primary, Eric Adams successfully pressed city officials to allow the opening of a Manhattan high-rise housing the Turkish Consulate General.Federal authorities are investigating whether Mayor Eric Adams, weeks before his election two years ago, pressured New York Fire Department officials to sign off on the Turkish government’s new high-rise consulate in Manhattan despite safety concerns with the building, three people with knowledge of the matter said.After winning the Democratic mayoral primary in July, Mr. Adams contacted then-Fire Commissioner Daniel A. Nigro in late summer 2021 and urged him to allow the Turkish government to occupy the building at least on a temporary basis. The building had yet to open because fire officials had cited safety issues and declined to sign off on its occupancy, the people said.The unusual intervention by Mr. Adams is being examined as part of a broader public corruption investigation by the F.B.I. and federal prosecutors in Manhattan that led to the seizure of the mayor’s electronic devices by federal agents early last week, the people said. The F.B.I. has been asking top Fire Department officials about Mr. Adams’s role in the matter since the spring, the people said.Mr. Adams’ intervention paved the way for the Turkish president, Recep Tayyip Erdogan, whose fondness for massive building projects was well known in Turkey, to preside over the grand opening of the $300 million, 35-story tower on his September 2021 visit to New York for the U.N. General Assembly, despite numerous flaws in its fire safety system, according to the people familiar with the matter and city records. The skyscraper in the center of New York City reflected Turkey’s “increased power,” Mr. Erdogan said at its ribbon-cutting.The federal criminal inquiry has focused at least in part on whether Mr. Adams’s 2021 campaign conspired with the Turkish government, including its consulate general in New York, to illegally funnel foreign money into its coffers, according to a search warrant obtained by The New York Times for an F.B.I. search this month of the home of the mayor’s chief fund-raiser.Asked for comment on Saturday morning, Mr. Adams’s campaign issued a statement from the mayor, who served as Brooklyn borough president until 2021.“As a borough president, part of my routine role was to notify government agencies of issues on behalf of constituents and constituencies,” Mr. Adams said. “I have not been accused of wrongdoing, and I will continue to cooperate with investigators.”A representative of the Turkish embassy in Washington, D.C., did not respond to requests for comment.Spokesmen for the F.B.I. and the U.S. attorney’s office for the Southern District of New York, whose prosecutors are also investigating the matter, declined to comment.At the time he contacted the Fire Department, Mr. Adams was completing his second term as Brooklyn borough president, a largely ceremonial job whose authority did not extend to the Manhattan site of the new consulate building, Turkevi Center, across First Avenue from the U.N. But his emergence as the mayoral primary winner in early July all but assured he would prevail in the November general election, given New York City’s heavily Democratic electorate. His influence among city officials had grown accordingly.Mr. Adams already had a long-running relationship with the Turkish consulate general, which paid for part of his trip to Turkey while he was Brooklyn borough president in 2015, according to a public filing.The warrant to search the home of Mr. Adams’s 25-year-old fund-raiser, Brianna Suggs, indicated that the investigation was examining the role of KSK Construction, a Brooklyn building company owned by Turkish immigrants that organized a fund-raising event for Mr. Adams on May 7, 2021.On that day, 48 donors, including the company’s owners, employees and their families, along with others in the construction and real estate industries, donated $43,600, Mr. Adams’s campaign reports show. Those contributions enabled him to obtain another $48,000 in public matching funds for a total of nearly $92,000. The city’s generous public matching funds program, intended to reduce the influence of money in politics, provides cash infusions to candidates by increasing donations from city residents up to $250 by a factor of eight. Mr. Adams’s campaign filings do not specify which donations were made through the fund-raising event.KSK Construction does not appear to have played a role in building the new consulate in Manhattan.Neither Mr. Adams nor his campaign has been accused of wrongdoing, and no charges are publicly known to have been filed in connection with the investigation. The mayor, who retained lawyers this week to represent him, his campaign and Ms. Suggs, has denied knowledge of any impropriety and defended the campaign’s fund-raising.After The Times reported on Friday that the F.B.I. had seized the mayor’s electronic devices, Mr. Adams and his lawyer, Boyd Johnson, issued statements saying that Mr. Adams was cooperating fully with the investigation and had instructed his employees to do the same.“I have nothing to hide,” Mr. Adams said in his statement.F.B.I. agents pulled the mayor aside after an event at New York University on Monday and seized two cellular phones and an iPad, which were copied and returned within days, the mayor’s lawyer has said.The agents who searched the Brooklyn home of Ms. Suggs the week before took computers, cellphones and other evidence, according to records obtained by The Times. The warrant for that search indicated that the inquiry was focused at least in part on whether anyone associated with Mr. Adams’s 2021 campaign had a motive or intent to “provide benefits, whether lawfully or unlawfully,” to the Turkish government, its nationals or the construction firm in exchange for contributions.It was unclear precisely when the investigation began, but this spring, two F.B.I. agents assigned to the same New York public corruption squad that executed the search warrant at the home of Ms. Suggs interviewed at least one senior Fire Department official who had been involved in the Turkevi Center approval process, three people with knowledge of the matter said. They asked detailed questions about the safety issues, the approval process and whether pressure had been brought to bear and by whom, the people said.Several months later, in midsummer, at least one other high-ranking Fire Department official was interviewed and asked similar questions, according to two of the people.And on Nov. 3, the morning after the search of Ms. Suggs’s home, F.B.I. agents knocked on the door of Commissioner Nigro and questioned him about Mr. Adams’s intervention and his communications with Mr. Nigro in the late summer of 2021, three people with knowledge of the interview said.Mr. Adams’s ties to the Turkish government and community stretch back years. As Brooklyn borough president, he actively wooed wealthy members of the Turkish community in south Brooklyn.In August 2015, the Turkish consulate in New York paid for Mr. Adams’s airfare, hotel and ground transportation for a trip to Turkey, according to financial disclosure records. There, Mr. Adams signed a sister-city agreement with Istanbul’s Uskudar municipality, one of several he executed with foreign cities he traveled to as borough president. He also visited Bahcesehir University, founded by the same Turkish philanthropist who founded Bay Atlantic University in Washington, D.C.The F.B.I. warrant for Ms. Suggs’s home also sought information about contributions from Bay Atlantic employees. Mr. Adams’s campaign filings show he received a total of $10,000 in contributions from five Bay Atlantic employees on Sept. 27, 2021, a week after the unveiling of Turkevi Center, and refunded the donations the following month.As recently as late last month, to honor the 100th anniversary of the Turkish republic, Mr. Adams presided over a flag-raising in Lower Manhattan and attended a celebration held at the Turkish consulate.Now housed in the new, 35-story glass tower, the consulate was erected at the cost of nearly $300 million, a sum that drew criticism in Turkey in 2021, when students protested the high cost of housing. It is reportedly Turkey’s most expensive foreign mission. Its curving facade was inspired by the crescent on the Turkish flag, while its tulip-shaped top is a nod to the country’s national flower, according to the architecture firm that designed it. The building includes not only consular offices, but apartments, a prayer room, an exhibition space and an auditorium, according to its architects.City records reveal problems for months before Mr. Erdogan’s visit in 2021 as Turkish government contractors sought to gain city approval to complete and occupy the building. On July 26, 2021, the Fire Department rejected the fire protection plan submitted by a consultant for the Turkish government, asking for changes. Around the same time, the Buildings Department issued a violation after a glass panel on the 17th floor fell off and plummeted 10 stories.Only 10 days before Mr. Erdogan was to preside over the opening of the new building, a senior Fire Department official informed Sparc Fire Protection Engineering, a consultant on the building project, that the department would not object to a temporary certificate of occupancy that would allow the building to be used if the consultant affirmed that the alarm system complied with the city building code, the records show.But a week later, on Sept. 17, the consultant reported numerous “deficiencies” involving smoke detectors, elevators, fans, doors and other issues. Sparc’s president told the city that the building would be staffed with guards on “fire watch” until the problems were resolved. The building is still operating under a temporary certificate of occupancy, records show.In a ceremony three days later, on Monday, Sept. 20, Mr. Erdogan presented the new consulate to the public and the press, calling it “a masterpiece” that would be a haven for American Muslims.In May of this year, after a man used a metal bar to shatter several of the consulate’s windows and threaten its security guards — an act the Turkish president called terrorism — Mr. Adams showed up in person to inspect the damage.

    F.B.I. Seizes Eric Adams’s Phones as Campaign Investigation Intensifies

    Days after a raid at Mr. Adams’s chief fund-raiser’s home, federal agents took the mayor’s phones and iPad, two people with knowledge of the matter said.F.B.I. agents seized Mayor Eric Adams’s electronic devices early this week in what appeared to be a dramatic escalation of a criminal inquiry into whether his 2021 campaign conspired with the Turkish government and others to funnel money into its coffers.The agents approached the mayor after an event in Manhattan on Monday evening and asked his security detail to step away, a person with knowledge of the matter said. They climbed into his S.U.V. with him and, pursuant to a court-authorized warrant, took his devices, the person said.The devices — at least two cellphones and an iPad — were returned to the mayor within a matter of days, according to that person and another person familiar with the situation. Law enforcement investigators with a search warrant can make copies of the data on devices after they seize them.A lawyer for Mr. Adams and his campaign said in a statement that the mayor was cooperating with federal authorities, and had already “proactively reported” at least one instance of improper behavior.“After learning of the federal investigation, it was discovered that an individual had recently acted improperly,” said the lawyer, Boyd Johnson. “In the spirit of transparency and cooperation, this behavior was immediately and proactively reported to investigators.”Mr. Johnson said that Mr. Adams has not been accused of wrongdoing and had “immediately complied with the F.B.I.’s request and provided them with electronic devices.” Mr. Adams had attended an anniversary celebration for an education initiative at New York University.The statement did not identify the individual, detail the conduct reported to authorities or make clear whether the reported misconduct was related to the seizure of the mayor’s devices. It was also not immediately clear whether the agents referred to the fund-raising investigation when they took the mayor’s devices.Mr. Adams, in his own statement, said that “as a former member of law enforcement, I expect all members of my staff to follow the law and fully cooperate with any sort of investigation — and I will continue to do exactly that.” He added that he had “nothing to hide.”The surprise seizure of Mr. Adams’s devices was an extraordinary development and appeared to be the first direct instance of the campaign contribution investigation touching the mayor. Mr. Adams, a retired police captain, said on Wednesday that he is so strident in urging his staff to “follow the law” that he can be almost “annoying.” He laughed at the notion that he had any potential criminal exposure.Spokesmen for the F.B.I. and the U.S. attorney’s office for the Southern District of New York, whose prosecutors are also investigating the matter, declined to comment.The federal investigation into Mr. Adams’s campaign burst into public view on Nov. 2, when F.B.I. agents searched the home of the mayor’s chief fund-raiser and seized two laptop computers, three iPhones and a manila folder labeled “Eric Adams.”The fund-raiser, a 25-year-old former intern named Brianna Suggs, has not spoken publicly since the raid.Mr. Adams responded to news of the raid by abruptly returning from Washington, D.C., where he had only just arrived for a day of meetings with White House and congressional leaders regarding the migrant influx, an issue he has said threatens to “destroy New York City.”On Wednesday, he said his abrupt return was driven by his desire to be present for his team, and out of concern for Ms. Suggs, who he said had gone through a “traumatic experience.”“Although I am mayor, I have not stopped being a man and a human,” he said.But he also said he did not speak with Ms. Suggs on the day of the raid, to avoid any appearance of interfering in an ongoing investigation.The seizure of Mr. Adams’s devices took place days after the F.B.I. raided the Brooklyn home of his chief fund-raiser, Brianna Suggs.Stephanie Keith for The New York TimesThe warrant obtained by the F.B.I. to search Ms. Suggs’s home sought evidence of a conspiracy to violate campaign finance law between members of Mr. Adams’s campaign, the Turkish government or Turkish nationals, and a Brooklyn-based construction company, KSK Construction, whose owners are originally from Turkey. The warrant also sought records about donations from Bay Atlantic University, a Washington, D.C., college whose founder is Turkish and is affiliated with a school Mr. Adams visited when he went to Turkey as Brooklyn borough president in 2015.The warrant, reviewed by The New York Times, indicated authorities were looking at whether the Turkish government or Turkish nationals funneled donations to Mr. Adams using a so-called straw donor scheme, in which the contributors listed were not the actual source of the money. The warrant also inquired about Mr. Adams’s campaign’s use of New York City’s generous public matching program, in which New York City offers an eight-to-one match of the first $250 of a resident’s donation.The federal authorities also sought evidence of whether any Adams campaign member provided any benefit to Turkey or the construction company in exchange for campaign donations.The Turkish Consulate in Manhattan on Thursday.Sara Hylton for The New York TimesThis is not the first time Mr. Adams or people in his orbit have attracted law enforcement scrutiny. In September, Eric Ulrich, Mr. Adams’s former buildings commissioner and senior adviser, was indicted by the Manhattan district attorney, Alvin L. Bragg, on 16 felony charges, including counts of bribetaking and conspiracy.In July, Mr. Bragg indicted six people, including a retired police inspector who once worked and socialized with Mr. Adams, on charges of conspiring to funnel illegal donations to the mayor’s 2021 campaign.Separately, the city’s Department of Investigation was investigating the role of Timothy Pearson, one of the mayor’s closest advisers, in a violent altercation at a migrant center in Manhattan.Mr. Adams has also had skirmishes with the law before becoming mayor. Soon after he was elected Brooklyn borough president, he organized an event to raise money for a new nonprofit, One Brooklyn, which had not yet registered with the state. The invitation list was based on donor rolls for nonprofits run by his predecessor, records show.A city Department of Investigation inquiry concluded Mr. Adams and his nonprofit appeared to have improperly solicited funding from groups that either had or would soon have matters pending before his office. Mr. Adams’s office emphasized to investigators that the slip-ups had occurred early in his administration and promised to comply with the law going forward.Earlier, while Mr. Adams was a New York state senator, the state inspector general found that he and other Senate Democrats had fraternized with lobbyists and accepted significant campaign contributions from people affiliated with contenders for a video lottery contract at Aqueduct Racetrack.In response to a Times examination of his fund-raising record in 2021, Mr. Adams attributed the scrutiny in part to his race.“Black candidates for office are often held to a higher, unfair standard — especially those from lower-income backgrounds such as myself,” he said in a statement then. “No campaign of mine has ever been charged with a serious fund-raising violation, and no contribution has ever affected my decision-making as a public official.” He added: “I did not go from being a person that enforced the law to become one that breaks the law.”Mr. Adams is not the first city mayor whose fund-raising has attracted federal scrutiny. In 2017, federal prosecutors examined episodes in which Bill de Blasio, who was then the mayor, or his surrogates sought donations from people seeking favors from the city, and then made inquiries to city agencies on their behalf.In deciding not to bring charges, the acting United States attorney, Joon H. Kim, cited “the particular difficulty in proving criminal intent in corruption schemes where there is no evidence of personal profit.” Mr. de Blasio received a warning letter about those activities from the city’s Conflicts of Interest Board.
