More than 1,000 current and former workers at the Department of Health and Human Services sent a letter to Congress Wednesday demanding the resignation of RFK Jr. over his pseudoscientific claims and his attacks on public health. This comes just days after The New York Times published a joint op-ed by nine former directors of the Centers for Disease Control and Prevention headlined “We Ran the C.D.C.: Kennedy Is Endangering Every American’s Health.” They write, “This is a time to rally to protect the health of every American. Congress must exercise its oversight authority over Health and Human Services.”
