The man who hopes to be President Donald Trump’s health secretary repeatedly asked to see “data” or “science” showing vaccines are safe – but when an influential Republican senator did so, he dismissed it.

Robert F. Kennedy Jr. told senators he would apologize if data shows vaccines don’t cause autism, but he cited a poorly conducted study to counter the dozens that show they do not.

Kennedy Jr. is revising his ethics agreement to divest his interest in litigation against an HPV vaccine maker and directing the stake to his adult son, The New York Times reported Friday, citing a written response to questions from senators who are weighing his confirmation as Health and Human Services secretary.

In his second day of confirmation hearings, Robert F. Kennedy Jr., President Donald Trump’s pick to lead the Department of Health and Human Services, refused to say that vaccines do not cause autism -- despite a large body of evidence showing there is no link.

Sen. Bill Cassidy, the top Republican on the Senate Committee on Health, Education, Labor and Pensions, concluded Thursday's hearing by saying he was "struggling" with the nomination due to Kennedy's vaccine positions. Kennedy notably refused to say vaccines don't cause autism as he faced pointed question from lawmakers.

In one of the most tense exchanges in a heated confirmation hearing, Senator Angela Alsobrooks called out past comments RFK Jr. made suggesting a different vaccine schedule for Black people.
