      Why Dr. Oz Is So Popular: American's Dysfunctional Attitude to Health

      by

      It’s perhaps an understatement to say that Americans have a difficult and contradictory relationship with our bodies.Every decade or so there is a new optimal way to feed ourselves, along with increasingly outlandish weight-loss regimens and whole categories of foods to champion or fear. We revel in the sophistication of medical science while widely distrusting it, and our politicians refuse to support a health care system in which everyone has access to basic, compassionate care. We are overly sedentary, but when we exercise we value strenuous over relaxing movement, strain over ease, striving over acceptance.No one embodies these obsessions better than Mehmet Oz, known as Dr. Oz to American daytime television viewers. Dr. Oz, who has styled himself as a kind of high priest in the church of American wellness, recently announced his candidacy in the Republican primary for an open Senate seat in Pennsylvania — a race that could decide control of the chamber.As Dr. Oz pursues this pivotal position, he should be seen as more than a celebrity turned politician. He’s rightly understood as a kind of quasi-religious leader, one who has set up his revival tent between a yoga studio and an urgent-care clinic, with the television cameras rolling. And many Americans are primed and ready to commit to his doctrine, which promises boundless possibility so long as we invest in individual responsibility — for our health and for everything else.This is worrying. As we collectively face yet another surge of coronavirus infections, leaders who extol individualism aren’t simply ineffective — they’re dangerous. If there’s anything we should be taking away from the past two years, it’s that autonomy and self-reliance are inadequate for 21st-century problems such as climate change, structural racism and the pandemic.The son of Turkish immigrants, born in Cleveland, and by all accounts a gifted surgeon, Dr. Oz gained notice as a frequent guest on “The Oprah Winfrey Show,” appearances that earned him the tag “America’s doctor” and led to introduction of “The Dr. Oz Show” in 2009. Over 13 seasons, the frequent topics of the show, which at its height regularly drew over a million viewers per week, could also be a list of Americans’ biggest bodily anxieties: weight loss, cancer, weight loss, aging, weight loss, sleep problems, poop problems and oh, weight loss.Dr. Oz often describes his path from cardiothoracic surgeon to TV health expert with missionary zeal: “As I performed thousands of surgeries on patients whose hearts had been ravaged by obesity, I realized we needed to better educate people on how to take part in their own care,” he explained in testimony before a Senate committee in 2014. “And for that reason I went into the public life, in an effort to teach.”And his announcement that he is now making the leap from daytime television to national politics took on a downright rapturous tone: “I’m running for the Senate to empower you to control your destiny,” he wrote in an essay in The Washington Examiner, “to reinvigorate our great nation, and to reignite the divine spark that we should always be seeing in each other.”The thousands of on-air hours Dr. Oz has spent ministering to Americans’ health concerns have made him a multimillionaire, and also a controversial figure. He has praised unproven supplements such as sage leaf tea, green coffee bean extract and raspberry ketones as “miracles” for weight loss and was chastised by senators for doing so. He was part of a team at Columbia University that patented a device to strengthen damaged heart valves, and also was the target of a letter of protest by physicians who asked why the university kept him on the faculty since he had shown “an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain.”On Covid-19, Dr. Oz has been particularly contradictory. He has promoted the safety and efficacy of vaccines and masks, but also initially recommended the use of the malaria drug hydroxychloroquine to treat Covid, based on a small and soon-discredited study. And his bid to represent Pennsylvania in the Senate is based on his promise to free Americans from some of the mask and vaccine mandates that his medical colleagues widely support.“We are Americans, and we can do anything we want,” he tweeted recently, alongside a Fox News clip of himself criticizing the Biden administration’s Covid-19 policies. “It’s time we get back to normal.”If there’s one consistent strain in Dr. Oz’s trajectory, it’s his belief in the power and responsibility of individuals to take control of their health and well being. Strikingly, in his essay announcing his candidacy, Dr. Oz doesn’t speak of unity or community, as many politicians do. Instead he identifies himself as a doctor who is “trained to tell it like it is because you deserve to hear our best advice and make your own decisions.”Perhaps it shouldn’t be surprising that this messianic diet guru would offer to cure us of all that ails us, physically and spiritually. The bigger question is why so many are ready to believe that organic, cold-pressed snake oil could stop us from aging, cure cancer, make us lose weight and end a pandemic?There’s something deeply American in Dr. Oz’s quest to reach a higher state via the improvement of the body. Its roots can be found, arguably, in the spiritual strivings of the Transcendentalists, the group of 19th-century nature-obsessed New England philosophers.Ralph Waldo Emerson’s notion of an “original relationship to the universe,” and his belief that there is a divine spirit in nature and in the human soul that does not require the doctrines and laws of organized Christianity, was radical in its time, but became foundational to the American concepts of individualism and self-reliance. These threads have been woven into everything from the prosperity gospel to my yoga teacher’s instructions to lift our arms over our heads and send our intentions “from Earth to sky through you.”The same ideas, filtered through the 21st-century preoccupation with wellness, quickly arrives at the idea that we shortchange ourselves by accepting what we are told by society — by doctors, scientists or government health officials — if it contradicts our individual instincts or opinions.It’s this American idea that health is a personal responsibility that gives rise to figures like Dr. Oz. In his individualist doctrine, when we get sick it’s generally at least partly our fault — there was probably a supplement we should have taken, a superfood we could have eaten more of or a junk food we should have eaten less of, a specialist we should have consulted.This American predilection for individualism is itself a public health risk in a pandemic, Ed Yong has argued in The Atlantic — one that has led to bad policy that puts everyone, especially the most vulnerable people, at risk. When reducing the spread of an infectious disease requires collective and individual action, “no one’s health is fully in their own hands,” Mr. Yong explains.And yet the idea that your health is in your own hands is key to Dr. Oz’s worldview. Despite what appears to be an earnest desire to help people, “The Dr. Oz Show” is not a public health effort. It’s a business. And by recommending products and services, Dr. Oz offers us opportunities to buy things — a very American way to feel empowered. He helps us find the perfect alchemy of diet, exercise and açaí berries to keep us spry, thin, and disease-free forever, as long as we can pay for it all out of pocket. In our individualist, consumerist society, wealth is health.This perhaps is the deeper, more primal appeal of what Dr. Oz is selling — the idea that if we can find the right guru, buy the right products and strive hard enough to manifest our best selves, we might just cheat death.Which of course we can’t. In this moment, when so much hangs in the balance, it’s a dangerous delusion.Annaliese Griffin is a journalist who covers culture, lifestyle and health.The Times is committed to publishing a diversity of letters to the editor.

      ‘Magic’ Weight-Loss Pills and Covid Cures: Dr. Oz Under the Microscope

      by

      The celebrity physician, a candidate in Pennsylvania’s Republican primary for Senate, has a long history of dispensing dubious medical advice on his daytime show and on Fox News.A wealth of evidence now shows that the malaria drugs hydroxychloroquine and chloroquine were not effective at treating Covid-19 and carried potential risks.But in the early months of the pandemic, Dr. Mehmet Oz, the celebrity physician with a daytime TV show, positioned himself as one of the chief promoters of the drugs on Fox News. In the same be-the-best-you tone that he used to promote miracle weight-loss cures on “The Dr. Oz Show,” he elevated limited studies that he said showed wondrous promise.His “jaw dropped,” he said, while reviewing one tiny study from France, calling it “a game changer.” In all, Dr. Oz promoted chloroquine and hydroxychloroquine in more than 25 appearances on Fox in March and April 2020.When a Veterans Affairs study showed that Covid-19 patients treated with hydroxychloroquine were more likely to die than untreated patients, that advocacy came to an abrupt halt.“We are better off waiting for the randomized trials” that Dr. Anthony S. Fauci, the nation’s leading infectious disease expert, had been asking for, Dr. Oz told Fox viewers.As Dr. Oz jumped last month into the Republican primary for Senate in Pennsylvania, where his celebrity gives him an important advantage in a crucial race, he tied his candidacy to the politics of the pandemic. He appealed to conservatives’ anger at mandates and shutdowns, and at the “people in charge” who, he said, “took away our freedom.”But the entry into the race of the Cleveland-born heart surgeon, a son of Turkish immigrants who has been the host of “The Dr. Oz Show” since 2009, also brought renewed scrutiny to the blemishes on his record as one of America’s most famous doctors: his long history of dispensing dubious medical advice.In ebullient language, he has often made sweeping claims based on thin evidence, which in multiple cases, like that of hydroxychloroquine, unraveled when studies he relied on were shown to be flawed.Over the years, Dr. Oz, 61, has faced a bipartisan scolding before a Senate committee over claims he made about weight-loss pills, as well as the opposition of some of his physician peers, including a group of 10 doctors who sought his firing from Columbia University’s medical faculty in 2015, arguing that he had “repeatedly shown disdain for science and for evidence-based medicine.” Dr. Oz questioned his critics’ motives and Columbia took no action, saying it did not regulate faculty members’ participation in public discourse.He has warned parents that apple juice contained unsafe levels of arsenic, advice that the Food and Drug Administration called “irresponsible and misleading.” In 2013, he warned women that carrying cellphones in their bras could cause breast cancer, a claim without scientific merit. In 2014, the British Medical Journal analyzed 80 recommendations on Dr. Oz’s show, and concluded that fewer than half were supported by evidence.Two researchers who worked on “The Dr. Oz Show” for a year during a break from medical school in the 2010s said in interviews that the show’s producers had originated most of its topics, often getting their ideas from the internet. But the researchers, whose job was to vet medical claims on the show, said that they had little power to push back, and that they regularly questioned the show’s ethics to one another and discussed quitting in protest.“Our jobs seemed to be endless fighting with producers and being overruled,” said one of the former researchers, both of whom are now physicians and insisted on anonymity because they said they feared that publicly criticizing him could jeopardize their careers.According to the former researchers, the show’s producers conjured an imaginary, typical viewer named “Shirley,” a woman whose children were grown and who had time to focus on herself. The standard advice for many ailments covered on the show — obesity, sluggishness, back pain — was exercise, the researchers said. But there was a quota on how often exercise could be mentioned.Shirley watched daytime TV and didn’t want to exercise, the researchers said they were told.Dr. Oz’s on-air medical advice on both his show and Fox News has taken on greater significance as he enters the political realm. His promotion of hydroxychloroquine grabbed President Donald J. Trump’s attention and contributed to early misinformation about the virus on the right.“Information can harm — that’s the key thing we need to appreciate here,” said Harald Schmidt, an assistant professor of medical ethics and health policy at the University of Pennsylvania. “His track record is pretty concerning. What we’ve seen so far does not instill confidence that this will help reasonable politics.”Dr. Oz, kneeling, rose to fame as a medical expert on Oprah Winfrey’s show.Jemal Countess/ Getty ImagesDr. Oz declined to to be interviewed for this article. His campaign manager, Casey Contres, said in a statement that the doctor had always put patients first and fought the “established grain” in medicine.“Dr. Oz believes it was truly unfortunate that Covid-19 became political and an excuse for the government and many in the corporate media to control the means of communication to suspend debate,” Mr. Contres added. “From the start, therapeutics meant to help with Covid-19 were regularly discounted by the medical establishment, and many great ideas were squashed and discredited.”Over the years, when pressed about offering unproven medical advice, Dr. Oz said his goal was to “empower” Americans to take control of their health. Grilled by senators in 2014 about false claims he made for weight-loss products, he said, “My job on the show, I feel, is to be a cheerleader for the audience.”He also said it was his right to use unscientific language. “When I feel as a host of a show that I can’t use words that are flowery,” he told the senators, “I feel like I’ve been disenfranchised, like my power’s been taken away.”In using the politics of the pandemic to shape his campaign for an open seat — one pivotal to Senate control in the midterms — Dr. Oz may be in tune with primary voters in Pennsylvania. The race has drawn candidates echoing Mr. Trump’s lie that the 2020 election was stolen, including Jeff Bartos, a developer, and Carla Sands, a former ambassador. David McCormick, a hedge-fund executive married to a former Trump administration official, is expected to join the field soon.The criticism Dr. Oz has received over the years for spreading misinformation has done little to tarnish his celebrity, as measured by his long-running TV program, whose distributor announced that the show would end in January when its host departs.Still, misinformation about the coronavirus emanating from the Trump White House and conservative news sites helped politicize the nation’s response to the pandemic, with deadly consequences in many Republican areas of the country.Although Dr. Oz spoke strongly in favor of masks and vaccines on Fox, his championing of unproven treatments early on sharply contradicted infectious-disease experts like Dr. Fauci who urged caution.In Pennsylvania, as around the country, counties that voted by large margins for Mr. Trump in 2020 have had lower vaccination rates and higher death rates from Covid than counties that voted heavily for President Biden.Yet at one point early in the pandemic, he said that reopening schools was an “appetizing opportunity” that might cause the deaths of “only” 2 to 3 percent of the population. He later walked back the statement.“I can’t believe he took the same oath that I did when we graduated,” said Dr. Val Arkoosh, an anesthesiologist and county official in the Philadelphia suburbs who is running in the Democratic primary for Senate. “That oath is about first doing no harm and always putting your patients first. I just think he’s a quack, to be honest.”In reply to Dr. Arkoosh, Mr. Contres said that Dr. Oz had performed thousands of heart surgeries and had “helped countless patients live a better life.”Dr. Oz testifying before the Senate subcommittee on consumer protection in 2014, when senators pressed him on claims he had made about weight-loss pills.Tom Williams/CQ Roll CallIn Dr. Oz’s 2014 appearance before the Senate subcommittee on consumer protection, Claire McCaskill, then a Democratic senator from Missouri, quoted a bit of his TV sales patter back to him: “You may think magic is make-believe, but this little bean has scientists saying they’ve found the magic weight-loss cure for every body type — it’s green coffee extract.”Dr. Oz admitted to the senators that his claims often “don’t have the scientific muster to present as fact.” A study he had cited about green-coffee bean extract was later retracted and described by federal regulators as “hopelessly flawed.” The supplier of the extract paid $3.5 million to settle charges by the Federal Trade Commission.Dr. David Gorski, a surgery professor at Wayne State University and longtime critic of alternative medicine, said Dr. Oz’s emergence as a Fox News authority on the coronavirus was no surprise him.“He could have gone the route of trying to be more reasonable and careful, vetting information, trying to reassure people where the science was still unsettled,” Dr. Gorski said. “But of course, that wouldn’t be Dr. Oz’s brand.”Early in the pandemic, on March 20, 2020, Dr. Oz appeared on several Fox News shows trumpeting what he called “massive, massive news” — a small study by a divisive French researcher, Dr. Didier Raoult, who claimed a 100 percent cure rate after treating coronavirus patients with hydroxychloroquine and azithromycin, or Z-Pak. At the time, with Covid-19 cases and deaths rising rapidly, hydroxychloroquine, an anti-malarial treatment, was being studied in multiple countries and adopted by hospitals without much evidence. Mr. Trump hyped it repeatedly at White House news conferences as part of his effort to minimize the crisis. Dr. Oz communicated with Trump advisers about speeding the drug’s approval to treat Covid. On March 28, the F.D.A. authorized its emergency use. On Fox, Dr. Oz noted that the Raoult study, with just 36 participants, was not a clinical trial, but his enthusiasm overran his caution. The study was the “most impressive bit of news on this entire pandemic front,” he gushed. On April 1, as Dr. Oz called on Gov. Andrew M. Cuomo of New York to lift restrictions on hydroxychloroquine, a public health expert, Dr. Ashish Jha of Brown University, cautioned Fox viewers that “the facts are just not in” on the drug.There was much confusion in the early days of the crisis about how the virus spread and how to slow it, with some expert views reversed by new information. The Raoult study quickly fell apart. Only six patients had received the two-drug combination, all with mild or early infections. One who was reported “virologically cured” on Day 6 was found to have the virus two days later. Six other patients treated only with hydroxychloroquine were omitted from the final results, including one who died and three others who were transferred to intensive care.On April 3, the board of the research journal that initially published the study said it did not meet the “expected standard.” In June 2020, the F.D.A. revoked emergency authorization of hydroxychloroquine to treat Covid-19. That November, the National Institutes of Health concluded that the drug held no benefit in treating Covid-19.By then, Dr. Oz’s once-daily appearances on Fox had tapered off. He was rarely seen on the network this year. But he returned to Sean Hannity’s show on Nov. 30 to announce his candidacy, seizing the opportunity to push back at critics of his medical career.“Doctors are about solutions,” he said. “But instead, people with good ideas are shamed, they’re silenced, they’re bullied, they’re canceled.”Susan C.

      The Pennsylvania Senate Candidate Running as the Anti-Dr. Oz

      by

      In the closely watched Pennsylvania Senate race, Val Arkoosh, a doctor in the Democratic primary, sees openings to raise her profile.Sign up here to get On Politics in your inbox on Tuesdays and Thursdays.Dr. Val Arkoosh is the Pennsylvania Senate candidate who is often an afterthought compared to the two front-running Democrats, John Fetterman and Conor Lamb.But a couple big recent developments — the chance of the Supreme Court sweeping away Roe v. Wade and the entry of Dr. Mehmet Oz into the race’s Republican primary — may give her underdog campaign new momentum.Dr. Arkoosh, a physician in obstetric anesthesiology and a top elected official in Montgomery County in the Philadelphia suburbs, is trying to pitch herself as a kind of anti-Dr. Oz.“It really does take a doctor to stand up to a doctor,” Dr. Arkoosh told me. “I don’t even know how he still has a license, with some of the stuff that comes out his mouth,” she said of his promotion of unproved Covid-19 treatments early in the pandemic.Dr. Oz, a celebrity doctor who, until recently, hosted “The Dr. Oz Show,” is well positioned, thanks to personal wealth and high name recognition, to become a front-runner in a G.O.P. field where no one has yet nailed down voters’ allegiance. The contest to fill Pennsylvania’s open Senate seat will be one of the hardest fought in the country in 2022, with majority control of the Senate at stake.Dr. Oz, who jumped into the race last week, is framing his candidacy as a conservative’s response to the pandemic, pushing back against mandates, shutdowns and limits to “freedom.” Dr. Arkoosh, on the other hand, helped lead an aggressive response to the pandemic as the leader of the Montgomery County board of commissioners. In an interview, she contrasted her efforts to ensure the safety of students in her county to Dr. Oz’s position on schools at the time: During the same month that she canceled graduation ceremonies last year, Dr. Oz urged on Fox News that schools should be open because it “may only cost us 2 to 3 percent in terms of total mortality” of the population. He later said he “misspoke.”In response to Dr. Arkoosh’s criticism, a spokeswoman for Dr. Oz’s campaign, Erin Perrine, pointed to his success as a heart surgeon and to his TV show and books, which she said “empowered millions to make better health care choices — even if it meant going against the medical establishment.”Dr. Arkoosh, 61, has struggled for attention from Democratic voters and donors in the shadow of the leaders of her primary: Mr. Fetterman, the lieutenant governor, and Mr. Lamb, a congressman. The two men are usually contrasted against one another as a progressive (Mr. Fetterman, who supported Bernie Sanders in 2016) versus a moderate (Mr. Lamb, who won a congressional district that voted for President Donald J. Trump). Dr. Arkoosh is liberal on issues — she wants to ban fracking and to add a public option to the health care marketplace — but what sets her apart may be demographics. Mr. Fetterman and Mr. Lamb are both from Allegheny County in Western Pennsylvania. They each argue that they are best suited to make inroads with white blue-collar voters. Meanwhile, Dr. Arkoosh’s base, Montgomery County — the state’s third most populous and the second richest — is ground zero for the suburban shift to Democrats in recent years. In all, Philadelphia and its suburbs in southeast Pennsylvania contribute 50 percent of the state’s Democratic primary voters.“In Montgomery County in 2020, we gave President Biden 66,000 more votes than we gave Hillary Clinton,” Dr. Arkoosh said. “It is where my base is, where my strength is.”Still, J. J. Balaban, a Democratic strategist in Pennsylvania, said that Dr. Arkoosh’s campaign had been underwhelming so far and that she was little known outside Montgomery County.“It costs a lot of money to get known statewide in Pennsylvania, and she appears to be coming up short,” Mr. Balaban told me. “At the moment, she doesn’t have enough funds to win the Philly market, let alone the state.”As of October, Dr. Arkoosh had $1 million in her campaign account, which includes a $500,000 personal loan, and she trails Mr. Fetterman’s $4.2 million on hand and Mr. Lamb’s $2.1 million. Her endorsement by Emily’s List, the abortion rights group, did not seem to have boosted her fund-raising much through September.Even so, the rising prominence of abortion as a potential motivator of Democratic voters in the midterm elections plays to Dr. Arkoosh’s strengths as a doctor. Her specialty means she administers anesthesia to women giving birth and women having abortions.“As a physician who has sat at the bedside of women who have had to make some of the most difficult decisions of their lives,” she said, “there is no place for any politician in those decisions.”Arguments before the Supreme Court last week suggested the conservative majority was ready to reverse or severely limit Roe v. Wade in a ruling next year.“I think this is going to be a very big issue,” Dr. Arkoosh said. “And I think this is going to be an issue that gets women, and particularly suburban women, out in numbers.’’On Politics is also available as a newsletter.

      Dr. Oz Says He’s Running for Senate in Pennsylvania

      by

      Dr. Mehmet Oz, who is running as a Republican for an open Senate seat, described his frustration with the “arrogant, closed-minded people in charge” who shut schools and businesses during the pandemic. Dr. Mehmet Oz, a celebrity physician known as the host of the “Dr. Oz Show,” announced on Tuesday that he would run for Senate in Pennsylvania, jumping into a crowded Republican primary for an open seat that is crucial to both parties’ quest for a Senate majority in 2022.Dr. Oz, a first-time candidate whose political views are little known, entered a G.O.P. field roiled by the recent withdrawal of a candidate endorsed by former President Donald J. Trump, in which most contenders are vying to show their loyalty to the Republican Party’s de facto leader.The Cleveland-born son of Turkish immigrants, Dr. Oz said he had been motivated to run because of the pandemic. In an online statement announcing his candidacy in The Washington Examiner, he criticized official responses to Covid-19 in terms embraced by conservatives.The pandemic, he wrote, has been mishandled by “elites” who stifled dissenting opinions, “mandated” policies and “closed our parks, shuttered our schools, shut down our businesses and took away our freedom.”Pennsylvania’s Democratic governor, Tom Wolf, was under attack through much of 2020 by Republicans for orders closing businesses during the height of the pandemic.Dr. Oz, 61, is a heart surgeon who first came to the public’s attention as a regular guest on “The Oprah Winfrey Show” before starting his own long-running daytime show, where he dispenses medical advice on all subjects. He has also appeared regularly on Fox News discussing Covid-19, sometimes making controversial statements. In April 2020, citing a medical journal, he said that opening schools “may only cost us 2 to 3 percent in terms of total mortality” of the population. After a backlash, he took to Twitter to say he “misspoke.”The previous month, Dr. Oz promoted hydroxychloroquine to fight the coronavirus, even though researchers at the time warned that the drug was unproven.Dr. Oz first came to the public’s attention as a regular guest on “The Oprah Winfrey Show.”George Burns/Harpo Productions, via Associated PressIn 2014, he was scolded before a Senate panel for using his TV show to promote foods and dietary supplements that falsely promised weight loss. Republicans in Pennsylvania expected that the entry of such a high-profile figure into the Senate race, one who is promising to spend large sums of his own fortune, would shake up a field without a front-runner. It follows the recent withdrawal of Sean Parnell, the Trump-endorsed candidate, who suspended his campaign after a judge gave primary custody of his children to his estranged wife, who had accused him of abuse.A number of Republican officials, whom Dr. Oz has been calling in recent weeks, said they thought voters would take the celebrity physician seriously.“The first thing I asked was, ‘Why are you running? Is this a vanity play?’” said Sam DeMarco III, the Republican chairman of Allegheny County, which includes Pittsburgh. But he said he was impressed with Dr. Oz’s seriousness in response to his questions. “My most important goal is to keep this seat in Republican hands come 2022, and I believe Dr. Oz’s entry into the race gives us a significant opportunity to do that,” Mr. DeMarco said.For Democrats, Pennsylvania represents perhaps their best chance to add a Senate seat to their column, since it is the only open seat next year in a state that President Biden carried in 2020. Senator Patrick J. Toomey, a Republican, is not seeking re-election. While the Democratic field has several seasoned candidates, including Lt. Gov. John Fetterman and Representative Conor Lamb, the Republicans in the race are less experienced and, with the exception of Dr. Oz, less well known. Most have leaned into their connections to Mr. Trump to win favor with a party base that fervidly supports the former president, including his false claims that he won the state last year. Jeff Bartos, a real estate developer, has called for a “full forensic audit” of the 2020 election in the state. Kathy Barnette, a former financial executive, has pushed claims of voter fraud on Newsmax and OAN. David McCormick, the chief executive of Bridgewater Associates, a giant hedge fund company, has been exploring getting into the race as well. Dr. Oz, who hosted Mr. Trump on his TV show in 2016 and was later named by him to a White House advisory council on sports and nutrition, is not known for denying the 2020 election results. He once described himself as a “moderate Republican” and said a political inspiration was Arnold Schwarzenegger, the former governor of California and a Trump critic. But in his statement announcing his run on Tuesday, Dr. Oz positioned himself more aggressively as a foe of elites and as someone who has “fought the establishment” throughout his career.“Elites with yards told those without yards to stay inside, where the virus was more likely to spread,” he wrote of the response to the pandemic, adding, “We must confront those who want to change the very soul of America and reimagine it with their toxic ideology.”A surgeon at Columbia University Irving Medical Center, his biographical entry there lists his Emmy Awards ahead of his publications. Dr. Oz earned medical and business degrees from the University of Pennsylvania. His principal residence, however, has long been in Bergen County in New Jersey, where he voted. He has also become a registered Pennsylvania voter, listing an address that is a home owned by his mother-in-law in Montgomery County, in the Philadelphia suburbs. Although rivals will surely accuse him of carpetbagging, one local Republican official said the issue may not play strongly with voters. “Being a newcomer, I don’t think that’s a drawback,” said Pat Poprik, the Republican chairwoman of Bucks County, the state’s fourth largest. “Issues are what voters are looking for.”Susan C.
