Trump taps Dr. Oz, a heart surgeon famous for appearing on Oprah who was later criticized for pushing fad diets and detoxes, to lead Medicare and Medicaid Services

“Dr. Oz will be a leader in incentivizing Disease Prevention, so we get the best results in the World for every dollar we spend on Healthcare in our Great Country,” Trump said in a statement. “He will also cut waste and fraud within our Country’s most expensive Government Agency, which is a third of our Nation’s Healthcare spend, and a quarter of our entire National Budget.”

Oz unsuccessfully ran for Senate in Pennsylvania as a Republican in 2022 and as a an outspoken supporter of Trump.

Earlier, Trump chose Howard Lutnick, head of brokerage and investment bank Cantor Fitzgerald and a cryptocurrency enthusiast, as his nominee for commerce secretary, a position in which he’d have a key role in carrying out Trump’s plans to raise and enforce tariffs.

Trump made the announcement Tuesday on his social media platform, Truth Social. In the post, Trump said Lutnick “will lead our Tariff and Trade agenda, with additional direct responsibility for the Office of the United States Trade Representative.”

Lutnick is a co-chair of Trump’s transition team, along with Linda McMahon, the former wrestling executive who previously led Trump’s Small Business Administration. Both are tasked with putting forward candidates for key roles in the next administration.

The nomination would put Lutnick in charge of a sprawling Cabinet agency that is involved in funding new computer chip factories, imposing trade restrictions, releasing economic data and monitoring the weather. It is also a position in which connections to CEOs and the wider business community are crucial.

An advocate for imposing wide-ranging tariffs, Lutnick told CNBC in September that “tariffs are an amazing tool for the president to use — we need to protect the American worker.” Trump on the campaign trail proposed a 60% tariff on goods from China — and a tariff of up to 20% on everything else the United States imports.

Mainstream economists are generally skeptical of tariffs, considering them a mostly inefficient way for governments to raise money and promote prosperity.

Lutnick had been considered for treasury secretary, a role that has been at the center of high-profile jockeying within the Trump world. At the same time, the treasury position is closely watched in financial circles, where a disruptive nominee could have immediate negative consequences on the stock market, which Trump watches closely.

The news also comes after billionaire Elon Musk and others in Trump’s orbit called on Trump to dump previous front-runner for treasury secretary, Scott Bessent, in favor of Lutnick. Musk said in his post that “Bessent is a business-as-usual choice, whereas @howardlutnick will actually enact change.”

Lutnick joined Cantor Fitzgerald in 1983 and rose through the ranks to be appointed president and CEO in 1991.

Lutnick also chairs financial technology company BGC Group, Inc. and the commercial real estate services firm Newmark Group, Inc.

Lutnick has donated to both Democrats and Republicans in the past, and once appeared on Trump’s NBC reality show, “The Apprentice.” He has become a part of the president-elect’s inner circle, and has shared the stage with Trump at events in the closing days of his campaign, including a rally at Madison Square Garden.

He came under criticism in the campaign’s final days for an interview with CNN in which he repeated Robert F. Kennedy Jr.’s debunked criticisms of vaccines.
