Susan Monarez has accused Health Secretary Robert F. Kennedy Jr. of “weaponizing public health”

The White House has dismissed Susan Monarez as director of the Centers for Disease Control and Prevention (CDC) after she refused to resign in a dispute over vaccine policy, with her ouster triggering turmoil and further resignations by senior health officials.

Monarez, who was confirmed by the Senate just last month, reportedly clashed with Health and Human Services Secretary Robert F. Kennedy Jr. over his push to lift vaccine mandates and rescind emergency authorizations.

“Susan Monarez is not aligned with the President’s agenda of Making America Healthy Again,” White House spokesman Kush Desai said in a statement on Wednesday, adding that she was terminated after refusing to step down voluntarily.

Her lawyers, Mark Zaid and Abbe Lowell, disputed the White House account, insisting Monarez “has neither resigned nor received notification” of her dismissal. They accused Kennedy of “weaponizing public health for political gain and putting millions of American lives at risk,” warning that her case highlights the “systematic dismantling of public health institutions.”

Monarez resisted pressure to endorse the changes or dismiss senior colleagues. According to multiple reports, she reached out to Senate Health Committee Chairman Bill Cassidy, whose support was pivotal during Kennedy’s confirmation hearings.
