U.S. President Donald Trump ended days of rumors and speculation when he confirmed May 12 that Marty Makary is resigning as FDA commissioner. Speaking with reporters before heading off to China for a two-day summit, Trump wouldn’t comment on whether he or someone else asked Makary to step down. However, while calling Makary a “wonderful man” and a “great guy, who’s a friend of mine,” the president acknowledged that “he was having some difficulty” at the FDA.
