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.

Robert F. Kennedy Jr.’s opinions about vaccine safety will likely lead to a few Senate Republicans to vote against his nomination.

Robert F. Kennedy Jr. goes before two two U.S. Senate hearings in his quest to head the nation's health department. Louisiana Sen. Bill Cassidy, a doctor, sits on both.

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

Cassidy is expected to challenge RFK Jr. on his vaccine skepticism and views on public health in today's 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.

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.

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.

Caroline Kennedy said in a scathing letter about her cousin, Robert F. Kennedy Jr., that she felt "an obligation to speak out."

Robert F. Kennedy Jr., President Trump’s nominee for health secretary, repeatedly confused Medicare and Medicaid. He also tried to convince senators he was not against vaccines, despite past statements.

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.
