Sen. John Fetterman, D-Pa., said he would vote to impeach his former political opponent Dr. Mehmet Oz as administrator of the Centers for Medicare and Medicaid Services (CMS) if Oz plans to protect government programs.

“If Dr. Oz is about protecting and preserving Medicare and Medicaid, I’m voting for this guy,” Fetterman tweeted.

Fetterman defeated Oz, a Republican, in the 2022 U.S. Senate race in Pennsylvania.

“Obviously our politics are different, and we have a history, but I don’t have any bitterness. I have nothing against him,” Fetterman said, according to CNN’s Manu Raju.

President-elect Trump has announced Oz as his choice to lead the CMS, which falls under the Department of Health and Human Services (HHS).

“America is facing a healthcare crisis, and there is perhaps no physician more qualified and capable than Dr. Oz to make America whole again,” Trump said in a statement. “Dr. Oz will work closely with Robert F. Kennedy Jr. to tackle the disease industrial complex and all the terrible chronic diseases left in its wake.”

Kennedy, who was nominated by Trump to lead HHS, applauded the president-elect’s decision to tap Oz as CMS administrator.

“I’m very excited that my friend @DrOz has agreed to run CMS. Thank you @realDonaldTrump for this excellent nomination. Welcome Dr. Oz to The Avengers. Let’s Make America Healthy Again!” Kennedy tweeted.

Oz said in a post on X that he is “honored” by Trump’s nomination.

“I look forward to serving my country to make America healthy again under the leadership of HHS Secretary @RobertKennedyJr,” he noted.

Sen. Rand Paul, R-Ky., congratulated Oz, calling him “an excellent fit” for the job.

“His medical background as a cardiothoracic surgeon and public health advocate makes him ideally suited for this position,” Paul said in a tweet.
