Centers for Disease Control and Prevention Director Susan Monarez was fired on Wednesday after refusing to resign from her post, a White House official told The Post. Monarez’s removal comes after she was reportedly issued an ultimatum by Health and Human Services Secretary Robert. F. Kennedy Jr: quit or be fired. “As her attorney’s statement makes abundantly clear, Susan Monarez is not aligned with the President’s agenda of Making America Healthy Again,” White House spokesman Kush Desai said in a statement. “Since Susan Monarez refused to resign despite informing HHS leadership of her intent to do so, the White House has terminated Monarez from her position with the CDC,” he added. The clash between Monarez, who was sworn in less than a month ago, and Kennedy stems from disagreements over vaccine policy, a Trump administration official told the New York Times.
