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.

Sanders, the senior minority party member on the committee, pressed Kennedy to concede that health care was a human right, as his father, Robert F. Kennedy, and his uncles, John F. Kennedy and Edward Kennedy, had done. Kennedy again did not give a definitive answer.

Robert F. Kennedy Jr. will face the Senate for two days of confirmation hearings in a bid become the leader of Health and Human Services.

The health committee chairman, Sen. Bill Cassidy, R-La., also has expressed concerns about Kennedy's anti-vaccine work. A physician, Cassidy said earlier this month he “had a frank conversation” and “spoke about vaccines at length” with Kennedy. On Tuesday, Cassidy told reporters that he is still unsure if he is backing Trump’s nominee.

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