WASHINGTON — President Trump will nominate Dr. Scott Gottlieb, a longtime drug industry financier and advocate for deregulation, to run the Food and Drug Administration, the White House said Friday.

Gottlieb, 44, is a physician and resident fellow at the conservative American Enterprise Institute. He trained at Mount Sinai School of Medicine, then pursued an unusual career that has taken him from hospitals to Wall Street to the FDA and back to Wall Street. A prolific writer and speaker on medical innovation, Gottlieb served as an FDA deputy commissioner under George W. Bush and has frequently testified before Congress.
