(FILES) US Food and Drug Administration (FDA) Commissioner Martin Makary testifies at an Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Subcommittee hearing on "A Review of the President's FY2026 Budget Request for the Food and Drug Administration" on Capitol Hill in Washington, DC, on May 22, 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.
