    We Watched Tim Walz’s Old Debates. Here’s What We Learned.

    He may not be a lofty orator, but he has shown an ability to deliver punchy critiques with Everyman appeal.Before he was known to the nation as an affable Midwestern dad and a vice-presidential nominee, Tim Walz was a fast-talking political long shot in an ill-fitting suit, spoiling, in his Minnesotan way, for a debate-stage fight.As he stood next to his opponent — a crisply dressed six-term Republican congressman — Mr. Walz, a teacher by training, offered viewers a stark contrast at that 2006 debate, hosted by KSMQ-TV. Mr. Walz cast their choice as one between a political insider focused on “moving up in elected office” and the alternative he said he represented: “I live in the world that most of you live in.”Mr. Walz sparred with Gil Gutknecht, then the Republican incumbent, in a 2006 congressional debate.KSMQ-TV, via C-SPANNearly two decades later, Mr. Walz is the one who has moved up in elected office, rising from congressman to governor and now, Vice President Kamala Harris’s running mate. He is set to face Senator JD Vance of Ohio, former President Donald J. Trump’s running mate, in a high-profile debate on Tuesday.Mr. Walz and his allies have tried to set expectations high for Mr. Vance, emphasizing his Yale Law School credentials. And Mr. Vance is a practiced verbal pugilist who seems to delight in combative exchanges on cable news and Sunday morning shows.But a review of a half-dozen recorded debates over Mr. Walz’s career makes clear that while the camo-wearing, car-tinkering man from Mankato may not be his party’s most stirring speaker, he is in fact a seasoned debater himself.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Satellite Images Reveal Where Russian Nuclear Weapons Could Be Stored in Belarus

    A New York Times analysis shows security upgrades unique to Russian nuclear storage facilities, at a Cold War-era munitions depot.The New York Times, Source: Maxar TechnologiesA newly added air defense system.A distinctive security checkpoint.And a triple fence around a bunker.These new security features and other upgrades at a munitions depot in central Belarus reveal that Russia is building facilities there that could house nuclear warheads. If Russia does move weapons to this location, it would mark the first time it has stored them outside the country since the fall of the Soviet Union in 1991.Russia already has nuclear warheads on its own soil that are close to Ukraine and NATO countries, but by basing some in Belarus, the Kremlin appears to be trying to accentuate its nuclear threat and bolster its nuclear deterrent.Russia’s president, Vladimir V. Putin, made reference to such a site early last year, saying Russia would soon be completing the construction of “special storage for tactical nuclear weapons” in Belarus.The New York Times analyzed satellite imagery and photos, and spoke with nuclear weapons and arms control experts, to track the new construction, which started in March 2023.The site is 120 miles north of the Ukrainian border at a military depot next to the town of Asipovichy. Some of the recently built structures there have features that are unique to nuclear storage facilities at bases inside Russia. For example, a new, highly secure area is surrounded by three layers of fencing, in addition to the existing security perimeter of the entire base. Another telltale sign is a covered loading area connected to what appears to be a concealed Soviet-era underground bunker.The New York Times, Source: Maxar Technologies More

    Haley Questions Trump’s Mental Fitness After He Mistakes Her for Pelosi

    Nikki Haley on Saturday escalated her attacks on Donald J. Trump, directly criticizing his mental acuity for the first time a day after the former president appeared to confuse her for Nancy Pelosi, the former House Speaker, during his Friday night rally in New Hampshire.In a news conference with reporters after her campaign event in Peterborough, N.H., Ms. Haley stopped short of calling Mr. Trump mentally unfit. But she did question whether he would be “on it” enough to lead the nation.“My parents are up in age, and I love them dearly,” she said. “But when you see them hit a certain age, there is a decline. That’s a fact — ask any doctor, there is a decline.”At his rally, the former president accused Ms. Haley of failing to provide proper security during the Jan. 6, 2021, attack on the Capitol, and connected her to the House committee that later investigated it. Ms. Haley, who was not holding a government role at the time of the attack, had been at home in South Carolina that day, according to campaign officials.The former governor of South Carolina and a United Nations ambassador under Mr. Trump, Ms. Haley, 52, opened her presidential bid this year with calls for “new generational leadership” and mental competency tests for candidates who are 75 or older. Though she has continued to emphasize those calls throughout her candidacy, she has reserved her most pointed attacks about mental fitness for President Biden and Congress, which she calls “the most privileged nursing home in the country.”The last time she came this close to knocking Mr. Trump directly was in October, after he criticized Israel’s prime minister, Benjamin Netanyahu, and referred to Hezbollah, the Iran-backed militant group, as “very smart.” Responding to those remarks, Ms. Haley said: “To go and criticize the head of a country who just saw massive bloodshed — no, that’s not what we need in a president.”Since her election night speech after the Iowa caucuses, Ms. Haley has been sharpening her case against the former president, lumping Mr. Trump with Mr. Biden as backward-looking and barriers to an American revival. At her event in Keene, N.H., she criticized Mr. Trump on his leadership tone and asked the audience if they really wanted two “fellas” in their 80s competing for the presidency.“I wasn’t even in D.C. on Jan. 6 — I wasn’t in office then,” she told the audience on Friday.In a subsequent news conference, she suggested that the country was in too vulnerable of a state to have a leader who is mentally unfit.“It’s a concern, and it’s what Americans should be thinking about,” she said.

    In New Hampshire, Chris Christie Still Sees a Path to Beat Trump

    As he stakes his candidacy on the state, Chris Christie is promising to find new ways to confront Donald Trump. “I’m not going to let him get away with being a coward,” he said in an interview.An upset victory over Donald Trump in New Hampshire could be a knockout blow, according to Chris Christie. He is staking his presidential campaign on winning the state.Emily Rhyne/The New York TimesIn his against-all-odds pursuit of the Republican presidential nomination, former Gov. Chris Christie of New Jersey has campaigned almost exclusively in New Hampshire: More than 90 percent of his events since February have been in the Granite State, according to a New York Times analysis.To hear Mr. Christie tell it, New Hampshire is his do-or-die state. If he doesn’t perform well here, that will probably be it.“I can’t see myself leaving the race under any circumstances before New Hampshire,” he said in an interview. “If I don’t do well in New Hampshire, then I’ll leave.”Much as he did during his White House bid in 2016, Mr. Christie is betting on the independent streak of New Hampshire voters to validate his candidacy and catapult him into contention. (Mr. Christie ultimately finished sixth in New Hampshire that year and dropped out a day later.)But while he blended into the crowd in the 2016 Republican primary contest, Mr. Christie occupies a nearly solitary position in this race: as the candidate offering the harshest criticisms of the runaway front-runner, former President Donald J. Trump.Mr. Christie’s central pitch to Republicans in New Hampshire is that they must vote with a sense of responsibility and urgency, because defeating Mr. Trump in the first-in-the-nation primary may be the only way to halt his march to the nomination.“The future of this country is going to be determined here,” Mr. Christie told a crowd this week at a local brewery, clutching an I.P.A. “If Donald Trump wins here, he will be our nominee. Everything that happens after that is going to be on our party and on our country. It’s up to you.”Though Mr. Christie has improved in recent polls, he still trails Mr. Trump in New Hampshire by double digits, and by much more in national polls and surveys of Iowa, the first nominating state.Mr. Christie signed autographs for supporters at an event on Monday in Rye, N.H.Sophie Park for The New York TimesYet in the interview, Mr. Christie said he still saw a path in New Hampshire. He pointed to numerous past candidates who “broke late” in the state, including Senator John McCain of Arizona during his 2000 campaign. Mr. Christie noted that Mr. McCain, who ended up winning New Hampshire, had driven around the state “basically riding around in a Suburban with two aides.”Mr. Christie is apparently trying to emulate that style. This week, he cruised around New Hampshire with only a driver and two staff members. His campaign does not have staff members on the ground in New Hampshire, and in all, he has only 11 staff members on the payroll, according to his campaign.In the trip to New Hampshire, his first since the opening Republican primary debate last month, Mr. Christie ratcheted up his criticisms of the former president.He now goes so far as to liken Mr. Trump to an autocratic leader, arguing that his conduct is beneath the office of the presidency. Mr. Christie tiptoes toward predicting how the former president’s criminal indictments will unfold, declaring that the country cannot have a “convicted felon” as its leader. And he needles Mr. Trump with subtle jabs at his idiosyncratic tendencies, taunting the former president for his love of cable television and apparent preference for well-done hamburgers.But despite his willingness to take on Mr. Trump, Mr. Christie has been denied his best shot at confronting the former president directly on the debate stage. Mr. Trump skipped the first debate and seems unlikely to attend the second one, which will be held in California at the end of the month.Mr. Christie, who has qualified for the second debate, said he had been drawing up contingency plans.“I’m not going to let him get away with being a coward and running away,” Mr. Christie said in the interview. “It could be meeting him out in front of his event as he’s making his way in. It could be confronting him on his way out. It could be actually going to the event. It could be a whole bunch of options that we’re going to try. I’m not going to tell them exactly which one I’m going to do, because then he would have his staff prepared for it and try to stop me.”Tell It Like It Is PAC, the super PAC supporting Mr. Christie’s bid, latched onto the New Hampshire-or-bust approach early on. Ninety-six percent of the roughly $1 million the group has spent on radio and television advertising has been in New Hampshire markets, according to data from AdImpact, a media tracking firm.Mr. Christie’s events grew more crowded as his swing through New Hampshire progressed, culminating with more than 150 people packed in a gym without air-conditioning in Bedford. Audiences at his events tended to applaud his anti-Trump broadsides.Mr. Christie was greeted with applause at an event in a crowded gymnasium in Bedford, N.H.Sophie Park for The New York TimesHis voters are holding out hope, but they acknowledge his path is tough.“You have to believe he’s got a chance,” said Irene Bonner, 75, of Meredith, N.H., who said she was normally apolitical but had been inspired to come to an event by Mr. Christie’s tough talk against Mr. Trump.“The party is so completely blinded by Trump, it just boggles my mind,” said John Bonner, her husband. “After everything’s gone down and the things he’s said and done. But at least Christie is speaking up.” He added, “The rest of them really aren’t.”If Mr. Trump does emerge as the nominee, Mr. Christie said, he will not back off in his criticism.“I can’t imagine that I’ll ever keep quiet,” he said in the interview. “I don’t think it’s in my personality, so I’ll continue to say what I believe is the truth.”He added: “But I’ll also be critical of Joe Biden, I’m certain, because I have been since he became president, and I suspect he is not going to do some sort of miraculous turnaround that’s going to win my support. So I think I probably have difficult things to say about both of them if I was not the nominee.”Asked if he would make an endorsement in a Trump-Biden rematch, the rarely pithy Mr. Christie was succinct: “No.” More

    Ecuador Presidential Candidate Is Assassinated During Rally

    The candidate, Fernando Villavicencio, had been vocal about ties between the state and organized crime, in a country roiled by violence tied to drug trafficking.Fernando Villavicencio was shot after speaking at a campaign rally in Quito, Ecuador.Karen Toro/ReutersA presidential candidate in Ecuador who had been outspoken about the link between organized crime and government officials was assassinated Wednesday evening at a political rally in the capital, just days before voting begins in an election that has been dominated by concerns over drug-related violence.The candidate, Fernando Villavicencio, a former journalist, was gunned down outside a high school in the capital, Quito, after speaking to young supporters. A suspect was killed in the melee that followed, and nine other people were shot, officials said.“There was nothing to be done, because they were shots to the head,” Carlos Figueroa, who worked for Mr. Villavicencio’s campaign and was at the rally, said of the candidate.Mr. Villavicencio, 59, was polling near the middle of an eight-person race. He was among the most vocal candidates on the issue of crime and state corruption.It was the first assassination of a presidential candidate in Ecuador and came less than a month after the mayor of Manta, a port city, was fatally shot during a public appearance. Ecuador, once a relatively safe nation, has been consumed by violence related to narco-trafficking in the last five years.“Outraged and shocked by the assassination,” President Guillermo Lasso wrote on the social media platform X, formerly known as Twitter, late Wednesday, blaming the death on “organized crime.”Mr. Lasso said the attackers had thrown a grenade into the street as a distraction as they tried to flee, but that it failed to explode. The national prosecutor’s office, also posting on the X platform, said that a suspect had been shot and apprehended amid crossfire with security forces, and had died shortly afterward. The office later said the authorities had carried out raids and detained six people in connection with the assassination.The nine other people shot included two police officers and a candidate for a National Assembly seat, according to the prosecutor’s office. There was no immediate information about the condition of the nine people; it was unclear late Wednesday night whether any of them had died.The killing is a major blow to a nation that was already suffering deep economic, social and political upheaval.“Electorally speaking, this year is the most violent in our history,” said Arianna Tanca, an Ecuadorean political scientist. “I think that what is going to change is the way we conceive of politics. I think that from now on it becomes a high-risk profession.”Ecuador, on South America’s western edge, witnessed an extraordinary transformation between 2005 and 2015 as millions of people rose out of poverty, riding the wave of an oil boom whose profits were poured into education, health care and other social programs.But more recently, the country has been dominated by an increasingly powerful narco-trafficking industry. Foreign drug mafias have joined forces with local prison and street gangs, unleashing a wave of violence unlike anything in the country’s recent history. Homicide rates are at record levels.Today, the violence is often horrific and public, meant to induce fear and exert control: There are regular reports of car bombings, beheadings and children being gunned down outside their schools.Complicating the situation, Mr. Lasso disbanded the country’s opposition-led National Assembly in May, a drastic move he made as he faced impeachment proceedings over accusations of embezzlement.The move, which is allowed under the Constitution, meant that new elections for president and legislative representatives would be held. The vote in which Mr. Villavicencio was supposed to compete is set for Aug. 20; a second round of voting will be held in October if no single candidate wins a clear victory.Investigators at the scene of the rally where Mr. Villavicencio was killed and others were wounded.Jose Jacome/EPA, via ShutterstockDiana Atamaint, the president of the National Electoral Council, said the election date would not be moved, citing constitutional and legal issues. In a televised statement early Thursday, Mr. Lasso declared a 60-day, nationwide state of emergency, a measure that involves the restriction of some civil liberties, and he said security forces would be deployed across the country. Such emergency declarations, meant for extraordinary circumstances, have become more common in recent years, but have done little to curtail Ecuador’s soaring violence.Mr. Lasso stressed, however, that the elections would proceed as scheduled. “This was a political crime, terrorism,” he said. “And there is no doubt that this assassination is an attempt to sabotage the electoral process. It is no coincidence this happened days before the first round of voting.”Mr. Villavicencio, who had worked as a journalist, activist and legislator, gained prominence as an opponent of correísmo, the leftist movement of former President Rafael Correa, who served from 2007 to 2017 and still holds major political sway in Ecuador. A presidential candidate who has Mr. Correa’s backing, Luisa González, is leading in the polls.Mr. Villavicencio wrote often about alleged corruption in the Correa government, which made him the subject of legal persecution and death threats. He briefly sought political asylum in Peru.In 2017, Mr. Villavicencio successfully ran for a seat in the National Assembly, where he served until the legislature was dissolved by Mr. Lasso.Mr. Correa, writing on the X platform late Wednesday, lamented Mr. Villavicencio’s death. “Ecuador has become a failed state,” he wrote. “My solidarity with his family and with all the families of the victims of violence.”Grace Jaramillo, an Ecuadorean professor of political science at the University of British Columbia who went to university with Mr. Villavicencio, remembered running against him in an election for student body president. He ran as a Trotskyist, and she represented a party called Democracy in Our House; both lost, to a student representing the Chinese Communist Party.“He was really a fighter all the time and very good at arguments,” Ms. Jaramillo said. “An arguer, a challenger. He used to love lively discussions.”After university, she said, Mr. Villavicencio became a union leader at Petroecuador, the country’s national oil company. Soon after Mr. Correa came to power, he started writing about government corruption as a political journalist.Ms. Jaramillo said she met with him at the time to give him advice. His house had been raided, and he had no money to fight the charges that had been brought against him, she said.“He was downtrodden. He felt bullied and diminished,” she added.But a few weeks ago, when she saw him on a trip to Quito, he was “really hopeful and enthusiastic,” Ms. Jaramillo said. “He was convinced that he could make it to the second round” of the presidential election.His death, she said, will be “a long-lasting memory of how difficult it is to fight corruption and to be safe at the same time.”Andrés R.

    With National Monument Designation, Biden Tries to Balance Electoral Realities

    The president has highlighted his climate actions as a way to spur domestic energy production and create blue-collar jobs, while nodding to environmental activists and tribal leaders.The president designated nearly a million acres of land in Red Butte, Ariz., as a national monument.Kenny Holston/The New York TimesAfter spending most of his appearance near the Grand Canyon describing how his fifth national monument designation would preserve sagebrush, bighorn sheep and 450 kinds of birds, President Biden said on Tuesday that protecting the land long held sacred by Native American leaders was not just a matter of the environment.“By creating this monument, we’re setting aside new spaces for families to bike, hunt, fish and camp, growing the tourism economy,” Mr. Biden said as he declared nearly a million acres near the Grand Canyon as a national monument, with the 300-million-year-old “majestic red cliffs” serving as his backdrop.“Preserving these lands is good not only for Arizona, but for the planet,” he said. “It’s good for the economy.”Mr. Biden has often framed his climate investments as a means to spur domestic energy production, one that would create thousands of jobs for blue-collar workers. But when he traveled to Arizona to announce a permanent ban on uranium mining in the area, he also nodded to other crucial constituencies: environmental activists and tribal leaders who have pressed the White House to make good on its ambitious campaign promises to protect the environment and ancestral homelands.The White House has presented Mr. Biden’s sales pitch for legislation aimed at cutting planet-warming greenhouse gas emissions, the Inflation Reduction Act, as a job-growth machine to appeal to the middle class. But the administration knows that those who care about protecting the environment and preserving lands stripped from tribal nations are crucial voters, particularly in the battleground state of Arizona.The balancing act was reflected during Mr. Biden’s visit to the mountainous range of Red Butte near the Grand Canyon, where he spoke of job creation while also acknowledging environmental activists and tribal leaders.Indigenous people, Mr. Biden said, “fought for decades to be able to return to these lands to protect these lands from mining and development to clear them of contamination to preserve their shared legacy.”The Biden administration has argued that the Grand Canyon region contains just about 1.3 percent of the country’s uranium reserves.Kenny Holston/The New York TimesThe White House hopes Mr. Biden’s message is received by not just Native Americans but also young and climate-conscious voters, many of whom have yet to be fired up by his economy-first message.About 71 percent of Americans say they have heard “little” or “nothing at all” about the Inflation Reduction Act one year after it was signed, according to a Washington Post-University of Maryland poll. And most Americans — 57 percent — disapprove of Mr. Biden’s handling of climate change, according to the poll. Recent polls also show that voter sentiment on the economy continues to drive the president’s negative approval ratings.Mr. Biden has been inconsistent in his efforts to protect federal lands and waters. This year he approved the Willow project, a large oil-drilling development in the pristine Arctic wilderness. The administration also approved more oil and gas permits in its first two years than President Donald J. Trump did in his, and agreed to a series of compromises in the Inflation Reduction Act, Mr. Biden’s signature climate law, to allow offshore oil and gas leasing in the Gulf of Mexico and Alaska’s Cook Inlet.“It’s a pick-your-battle environment,” said Joel Clement, a former policy director at the Interior Department.Mr. Clement, who is now a senior program officer at the Lemelson Foundation, a philanthropic group funding work on climate change, said he believed the Biden administration was intent on protecting Indigenous lands and culture, and also on blocking as much fossil fuel production as it could.But, he said, “The calculus revolves around how much damage they can weather from the right on each of these things.”The Biden administration needs to amp up its climate change messaging as campaign season heats up, said Anthony Leiserowitz, the director of the Yale Program on Climate Change Communication, which has conducted surveys on Americans’ climate opinions since 2007.While the message about jobs and the economy might be a winning strategy in a general election, Mr. Leiserowitz said Mr. Biden’s base of climate-focused voters wanted to see the president use the bully pulpit to talk more about replacing fossil fuels, the burning of which is dangerously heating the planet.“They have more teachable moments to talk about climate change with the American people than any other president in history because we are getting hit every day by another two-by-four of climate extremes on steroids,” Mr. Leiserowitz said.Mr. Biden leaned into that message on Tuesday, describing his efforts to combat the effects of climate change, including investing $720 million for Native American communities to ease the impact of droughts and rising sea levels. Standing before an Arizona delegation as well as tribal leaders donning traditional attire, Mr. Biden framed the Inflation Reduction Act as the biggest investment in climate conservation and environmental justice on record.But his announcement also highlighted the risks Mr. Biden faces as he seeks to conserve lands while also promoting the expansion of clean energy. Uranium is a fuel most widely used for nuclear plants, a key source of energy that does not produce carbon dioxide emissions.As countries work to curb planet-warming greenhouse gasses, competition for uranium is expected to increase, according to experts. The United States imports the majority of its uranium, from Kazakhstan, Canada, Australia and Russia.Paul Goranson, the chief executive of enCore Energy, which has mining claims in the Grand Canyon area, said the uranium found there is of a higher grade than in other parts of the United States. Cutting off that supply, he said, will keep the United States reliant on imports, which could have an impact on national security and hurt the Biden administration’s ability to develop zero-emissions energy sources to fight climate change.“It seems the timing is a bit inconsistent with the president’s objectives for clean energy,” Mr. Goranson said. “It doesn’t seem to be aligning with his stated clean energy targets.”The Biden administration has argued that the Grand Canyon region contains just about 1.3 percent of the country’s uranium reserves. Environmental groups also noted that because the area was under a 20-year moratorium imposed during the Obama administration, no mining would have occurred for at least a decade anyway.Republicans blasted Mr. Biden’s decision this week. Senator John Barrasso of Wyoming, the top Republican on the Senate Energy and Natural Resources Committee and a supporter of nuclear energy, accused the president of “supporting our enemies” by blocking uranium production. American companies currently pay around $1 billion a year to Russia’s state-owned nuclear agency to buy uranium.The White House’s balancing act of framing its agenda as a boon to domestic investment and job growth, as well as a way to combat climate change and advance environmental justice, will continue throughout the re-election campaign, according to senior White House officials. After Mr. Biden was endorsed by the four largest environmental groups in the United States in June, the president celebrated days later at a rally for union workers.“The investment isn’t only going to help us save the planet, it’s going to create jobs — lots of jobs, tens of thousands of good-paying union jobs,” Mr. Biden reminded A.F.L.-C.I.O. members at the rally in Philadelphia.That strategy was evident on Tuesday. As Mr. Biden talked about the importance of protecting the country’s natural wonders, Vice President Kamala Harris joined Labor Department officials in Philadelphia to speak to construction workers about efforts to raise their wages.And after the event at the Grand Canyon, Mr. Biden traveled to Albuquerque, where he will describe how his signature climate and clean energy bill also creates manufacturing jobs in the clean energy sector.A group gathered to see President Biden.Kenny Holston/The New York TimesJohn Leshy, a public lands expert who served in the Interior Department during the Clinton and the Carter administrations, said trade-offs between developing renewable energy to fight climate change and conserving and protecting public lands will only increase in the years to come.“We’ve got a catastrophe in the offing if we don’t move rapidly to decarbonize,” Mr. Leshy said. “I don’t think that means opening up the Grand Canyon to uranium mining everywhere, but in some situations it does mean we’re going to have to grit our teeth” to allow for more minerals development, he said.For Carletta Tilousi, a member of the Havasupai Tribe, Mr. Biden’s monument designation means that her ancestors “are finally going to be feeling rested.”“A lot of these areas are in places where there were once gathering sites of tribal people and many years ago, hundred years ago, where our ancestors once roamed and we still roam today here,” she said. “But I believe those areas are very important to our existence.” More

    Chris Christie Meets With Zelensky in Surprise Trip to Ukraine

    Former New Jersey Gov. Chris Christie, who is running for the Republican presidential nomination, made an unannounced visit to Ukraine on Friday to meet with President Volodymyr Zelensky, whom he praised for demonstrating “the resolve it takes to survive a war and ultimately win it.”Mr. Christie is the second 2024 G.O.P. hopeful to visit Mr. Zelensky in Kyiv, signaling his support for Ukraine in a war that has divided the Republican candidates and Republican voters. Former Vice President Mike Pence traveled to Ukraine in June.Escorted by a Ukrainian security detail, Mr. Christie visited sites near Kyiv that were devastated during Russia’s drive toward the Ukrainian capital in the first months of the invasion, including Bucha, a Kyiv suburb where Russian soldiers massacred more than 400 people last April.“There are hundreds of millions of people in our country who support you,” Mr. Christie told local officials in Moshchun, a village northwest of Kyiv, during a visit to a memorial overlooking a trench used by Ukrainian soldiers during a battle in March of last year.The United States has provided Ukraine with billions of dollars in military and security assistance since Russia’s invasion more than a year ago, with President Biden often framing the extraordinary level of support as part of an existential fight for democracy against authoritarian aggression as well as being vital to national security interests.A majority of Americans continue to approve of U.S. aid to Ukraine in the conflict, but that support has softened over time, owing mostly to increasing Republican opposition. The percentage of Republicans saying the United States is providing “too much” support to Ukraine has grown to 44 percent from 9 percent since the Russian invasion in February 2022, according to polling by the Pew Research Center.That shift has been led by former President Donald Trump, whose first impeachment resulted from his 2019 phone call to Mr. Zelensky pressuring him to investigate Mr. Trump’s political rivals after freezing hundreds of millions of dollars in aid to Ukraine. Mr. Trump, who maintained that he did not pressure Mr. Zelensky, has said defending Ukraine is not a vital national interest for the United States.In a CNN town hall in May, he refused to say whether he would continue President Biden’s policy of supplying weapons and ammunition to Ukraine if he returned to the White House, or whether he supported Mr. Zelensky or Russian President Vladimir Putin in the conflict.“I want everybody to stop dying,” Mr. Trump said.Mr. Christie said that in his meeting with Mr. Zelensky, which was closed to reporters, the Ukrainian president “spoke about his desire for there to be bipartisan support for Ukraine.” He said the subject of Mr. Trump did not come up. “There was no conversation from him about the race that I’m in,” Mr. Christie said. He said Mr. Zelensky told him, “Whoever the next president is, I need to have that person feel a partnership with Ukraine.”Ukraine policy is an area in which Mr. Christie, a 2016 Trump rival-turned Trump adviser-turned Trump critic, has sought to draw a sharp contrast between himself and the former president, calling Mr. Trump a “puppet of Putin” and mocking his recent claim that he could negotiate “in one day” a truce between Mr. Zelensky and the Russian leader.“Move over Churchill, Trump is here to save the day,” Mr. Christie tweeted last month.“I think he really likes strongmen,” Mr. Christie said late Thursday of Mr. Trump in an interview aboard a train to Kyiv. “I think those are his role models in terms of the way he would like to control power if left to his own devices.”Mr. Christie also criticized the Biden administration for not doing more to support the Ukrainian war effort, in particular its delays in supplying Mr. Zelensky’s government with F-16 fighter jets, which Mr. Biden had resisted doing for a year before approving the move in May. “I would have been sending them months ago,” Mr. Christie said. He also favors NATO membership for Ukraine.A New York Times/Siena poll this week showed Mr. Christie trailing far behind Mr. Trump, who remains the overwhelming favorite in the race, with the support of 54 percent of likely Republican primary voters.“I wish you political luck,” Anatolii Fedoruk, the mayor of Bucha, told Mr. Christie during his visit to the city.“We all hope for that, right?” Mr. Christie replied, clapping him on the back.
