RFK Jr. remains HHS Secretary more than 18 months after Senate confirmation, with ongoing public activity including April 2026 congressional testimony on administration health priorities and budget proposals plus recent policy announcements on transplants and advisory panels. No official statements, White House signals, or Senate actions indicate plans for removal or resignation by year-end, despite internal controversies and staff changes. Traders assign roughly 68% probability to him staying in place through December 31, reflecting the typical durability of cabinet appointments absent major scandals or policy reversals and the administration's continued alignment on his role.
