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.

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.

Robert F. Kennedy Jr. also disclosed that he had reached at least one settlement agreement with a company or individual that has accused him of “misconduct or inappropriate behavior.”
