Calley Means, a prominent advocate for the Make America Healthy Again (MAHA) movement and a senior adviser at the Health and Human Services Department, resigned from the Trump administration on Thursday. Means, who also advised Health Secretary Robert F. Kennedy Jr., cited frustrations with the administration's pace on key health and food security policies, including the regulation of glyphosate and the definition of ultraprocessed foods. His departure comes amid growing discontent among MAHA supporters over stalled initiatives. White House spokeswoman Allison Schuster expressed gratitude for Means' contributions, and fellow activist Kelly Ryerson praised his efforts in fighting for food-related policies.
