**RFK Jr. remains HHS Secretary with strong backing from President Trump more than 18 months after his narrow February 2025 Senate confirmation.** Recent leadership reorganizations at the department, continued implementation of the Make America Healthy Again agenda, and public appearances such as a planned September 2026 address at a Children’s Health Defense event signal ongoing engagement in the role rather than any exit signals. Critics including Democratic lawmakers, public health organizations, and over 1,000 current and former HHS employees have called for his resignation amid disputes over vaccine policies, food safety recalls, and staffing changes, but these have produced no Republican-led removal efforts. Federal court rulings have temporarily blocked some vaccine advisory and schedule alterations, with appeals underway, yet these legal hurdles have not altered the administration’s support. With the 2026 midterms approaching and no public indications of waning White House confidence, traders assess the probability of departure by year-end as limited, reflecting the central role of presidential backing in cabinet tenure.
