Facing intense scrutiny from senators over his potential profit from vaccine lawsuits while serving as the nation's health secretary, Robert F. Kennedy Jr. said that if he is confirmed he will not collect fees from litigation against the drugmakers of a cervical cancer vaccine.

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.

The man who hopes to be President Donald Trump’s health secretary says he needs to see data showing vaccines are safe, but he dismissed the evidence shown by an influential Republican senator.

The hearings were packed to capacity with protesters and fans, while the spillover crowd hung out in hallways and overflow rooms.

Robert F. Kennedy Jr.’s nomination to be the nation’s top health official is uncertain after a key Republican joined Democrats to raise persistent concerns over the nominee’s deep skepticism of routine childhood vaccinations that prevent deadly diseases.

Democrats focused on Kennedy's anti-vaccine advocacy. Republicans probed the former Democratic leader on his abortion and agriculture views.
