Dr. Marty Makary resigned as FDA commissioner on Tuesday, ending a controversial tenure at the health agency.
In a post on Truth Social, President Donald Trump said Kyle Diamantas, who previously worked as the top food official at the FDA, will step in as acting commissioner. In earlier remarks to reporters, Trump called Makary a “wonderful man” and said “He’s going to go on, and he’s going to lead a good life.”
Trump shared a second post that showed a purported resignation text from Makary. In the message, Makary touted his role in the FDA’s priority review process that sped up some drug approvals, among other changes to the agency.

Makary reportedly slow-walked a safety review of the pill, which can be mailed to states that have limited abortion. Makary’s successor will inherit that review and the tricky politics associated with abortion.
The senior administration official said they couldn’t point to one issue that led to Makary’s ouster, but said it was a buildup of many problems. Abortion was one of those issues.
Despite the controversy around recent drug rejections, the pharmaceutical industry appears wary about a shakeup at the top of the FDA.
