Trump has nominated Dr. Mehmet Oz to serve as administrator of the Centers for Medicare and Medicaid Services, which runs Medicare, Medicaid and other health care functions. Oz, of course, hosted a daytime talk show for 13 years before exiting to run for an open Senate seat in Pennsylvania in 2022. He lost that seat to John Fetterman.

If confirmed by the Senate, Oz would be responsible for the programs — Medicaid, Medicare and the Affordable Care Act — that more than half the country relies on for health insurance.
