Dr. Anthony Fauci talks family, career and what's next

Dr. Anthony Fauci may be stepping down from his role as chief medical advisor to the president in December, but the immunologist says he's "not even close" to completely retiring.

"I don't know precisely what I'm going to do because I really can't negotiate a post-government job while I'm in government," he said. "My broad general theme, even though I don't know the venue in which it's going to happen, would be to continue to stay in the arena of science, medicine and public health."

Fauci has served under seven different presidents, covering health crises from Ebola to the AIDS epidemic. Over the course of his five-decade career, the physician has faced both criticism and accolades from officials and the public.
