President-elect Donald Trump has tapped several TV personalities for key posts in his incoming administration, including Dr. Mehmet Oz to run the Centers for Medicare and Medicaid Services, an agency that oversees health coverage for 150 million people. Oz, who ran an unsuccessful campaign for Senate in Pennsylvania in 2022, supports privatizing Medicare. His background really has nothing to do with the Centers for Medicare and Medicaid Services," says Dr. Robert Steinbrook, director of the Health Research Group for Public Citizen.
