For the first time in modern American history, a skeptic of medical research could be responsible for safeguarding public health.

Robert F. Kennedy Jr. was confronted with a number of his baseless claims and a vexing abortion issue. But Republican senators treaded lightly.

Caroline Kennedy, daughter of former President John F. Kennedy, warned senators of her “predator” cousin ahead of his first confirmation hearing on Wednesday. In a letter first reported by The Washington Post, she wrote that his victims included family members and parents of sick children.

RFK Jr. claimed he is not “anti-vaccine” and appeared unfamiliar with key aspects of healthcare insurance programs in his confirmation hearing.

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

The former U.S. ambasador — the last surviving child of Jacqueline and John F. Kennedy — urged lawmakers to reject RFK Jr.’s nomination as health secretary.

Caroline Kennedy, a member of the famed U.S. political family, urged senators on Tuesday to reject her cousin Robert F. Kennedy Jr.'s nomination to lead the top U.S. health agency, calling him a "predator" and his healthcare views "dangerous.

Robert F. Kennedy Jr.'s famous name, populist stances and loyal following have earned him President Donald Trump’s support, but will that get him the votes he needs from the Republican-controlled Senate to become the nation’s top health official?
