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.

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

Some GOP senators want public commitments from Robert F. Kennedy Jr. before deciding whether to support him as the next secretary of the Department of Health and Human Services, signaling that President Donald Trump’s pick will have to win over uncertain Republicans in order to secure the job.

Louisiana Sen. Bill Cassidy will be at the center of the first hearing for Robert F. Kennedy Jr.’s controversial Health and Human Services Secretary nomination.

Here's when and where Robert F. Kennedy will get his first hearing as President Trump's nominee for secretary of Health and Human Services.

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

Mr. Kennedy appears to have most Republicans behind him as he seeks the job of health secretary, though he couldn’t escape his past stances on vaccines and abortion.

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.
