Marty Makary resigned as FDA commissioner, with one source telling CBS News that his departure stems from a dispute over flavored e-cigarettes — specifically that Makary had refused to approve fruit-flavored vaping products from Glas Inc. but was pressured by the administration to do so before the FDA approved them on May 6, according to CBS News. Said President Trump on the South Lawn: "Marty's a terrific guy, but he's going to go on and he's going to lead a good life. He was having some difficulty." Kyle Diamantas is expected to serve as acting commissioner.
