Hundreds of US Health and Human Services (HHS) employees have written to Secretary Robert F. Kennedy Jr., urging him to stop spreading inaccurate health information. The letter cites Kennedy’s past claims undermining the CDC, labeling it a “cesspool of corruption,” and his policies cutting thousands of HHS jobs, which have created gaps in disease detection, worker safety, and chronic disease prevention. Staff linked his rhetoric to public distrust, including a recent CDC shooting. Critics also note his history of vaccine misinformation and funding cuts for mRNA research. Former CDC director William Foege warned that Kennedy’s words pose serious public health risks.
