The U.S. Senate Finance Committee could vote as soon as Tuesday on Robert F. Kennedy Jr.’s controversial nomination to be secretary of Health and Human Services, the cabinet position in charge of protecting the health of the American people.

Kennedy Jr., President Donald Trump’s pick to head the US Department of Health and Human Services, was endorsed by the Senate Finance Committee after two tough hearings. His nomination will now advance to a full Senate vote.

During health secretary nominee Robert F. Kennedy Jr.'s Jan. 29 Senate confirmation hearing, Sen. Elizabeth Warren, D-Mass., grilled Kennedy over his involvement in lawsuits against vaccine manufacturers.

GOP senators say they'll keep a close eye on RFK Jr., the long-time vaccine critic poised for the U.S.'s top health care role.

Kennedy, who has refused to acknowledge vaccines don’t cause autism, later won the support of a key Senate committee, getting a step closer to confirmation.

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.

Sen. Bill Cassidy, whose “yes” vote advanced Kennedy’s nomination as health secretary, said Kennedy promised to maintain a key CDC vaccine panel without change.

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.
