Oz would serve under Robert F Kennedy Jr. — who Trump nominated as secretary of the U.S. Department of Health and Human Services — if Oz and Kennedy are confirmed by the Senate or appointed during a Senate recess.

“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 posted to social media. “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 was a cardiothoracic surgeon, professor at Columbia University’s Vagelos College of Physicians and Surgeons and co-inventor of the Abbott MitraClip. But it was in television where he made his fortune — and drew criticism for various controversies.
