Jerome Adams, who served as US surgeon general during President Donald Trump’s first administration, is calling for Health and Human Services Secretary Robert F. Kennedy Jr. to be fired as controversy continues to swirl over his handling of vaccine approvals.

When asked by CNN’s Victor Blackwell on Saturday if Trump should fire Kennedy, Adams said, “I absolutely believe that he should for the sake of the nation and the sake of his legacy.”

Adams’ comments come after a contentious hearing on Capitol Hill earlier this week, where Kennedy was grilled by both Democrats and Republicans about his views on vaccines and the recent exodus at the Centers for Disease Control and Prevention, including the resignation of its director, over tighter vaccine policies Kennedy was pushing.

“I’m deeply concerned about the health and safety of our nation under RFK’s current leadership,” Adams told Blackwell, later adding: “I absolutely believe he is uniquely damaging the credibility of federal agencies like the CDC, (National Institutes of Health, Food and Drug Administration) and he’s putting us at risk.”

The former surgeon general also raised concerns about Trump’s close relationship with Kennedy, arguing that the president should take charge of health policy.
