(FILES) (L/R) US Secretary of Health and Human Services Robert F. Kennedy Jr., Food and Drug Administration (FDA) Commissioner Martin Makary and President Donald Trump attend an announcement event on prescription drugs in the Oval Office of the White House in Washington, DC, on September 30, 2025. President Donald Trump said on May 12, 2026, his US Food and Drug Administration chief, Marty Makary, is leaving his post, a departure that follows weeks of political tumult at the powerful agency. During his tenure atop the sprawling body responsible for overseeing vaccines, medicine and food, Makary managed to upset figures across industry, politics and public health over a range of issues, and most recently faced pressure from the Republican president to sign off on fruit-flavored vapes.
