From John F. Kennedy and Jackie Kennedy's descendants to how they relate to Robert F. Kennedy Jr., here's a look at one of the most famous families in American history

Kyra Kennedy, 29, is the youngest daughter of health secretary nominee Robert F. Kennedy Jr.

Robert F. Kennedy Jr.'s record of questioning childhood vaccine safety came under fire from a key Republican at the Trump HHS pick's confirmation hearing.

Kathleen "Kick" Kennedy is the eldest daughter of Robert F. Kennedy Jr., who could be confirmed as health secretary in Trump's administration.

The top Republican on the Senate's chief health committee, Sen. Bill Cassidy, R-La., indicated Thursday that he was “struggling" to confirm Kennedy over his inability to admit vaccines are safe and don't cause autism.

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.

President Donald Trump's new appointee to head US Human and Health Services, Robert F. Kennedy, is likely to make some changes to Medicaid, his testimony to the Senate Finance Committee revealed Wednesday.

As he seeks to lead the health department, Mr. Kennedy wore a thin tie dotted with feathered creatures to cap a classic suit.

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.

Caroline Kennedy has released a scathing letter describing her cousin Robert F Kennedy as a cruel, unqualified and dangerous.

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.

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