Nine former CDC directors warn Robert F. Kennedy Jr.'s leadership endangers public health.

Nine former CDC directors have warned that Robert F. Kennedy Jr., newly appointed as Health and Human Services Secretary, is endangering public health. They criticize his firing of CDC director Susan Monarez, weakening of disease prevention programs, and focus on unproven treatments over vaccines. The group, spanning administrations from Carter to Trump, urges Americans to be alarmed by these developments, regardless of political beliefs. Senator Bernie Sanders has called for Kennedy to resign, citing his stance on vaccines as a threat to public health.
