Robert F. Kennedy Jr.'s chances of confirmation as Health and Human Services secretary appeared to hinge Thursday on convincing a handful of Senate Republicans that he would adhere to accepted science when it comes to vaccines.
During a hearing before the Health, Education, Labor and Pensions Committee, Kennedy faced tough questioning from Democrats and a few Republicans about his long history advocating against vaccinations and disseminating misinformation about the disproved link between vaccines and autism. In contrast, several Republicans expressed support for Kennedy's stance on vaccines.

Three key Republicans pressed the prominent vaccine critic to moderate his past positions and unequivocally endorse vaccinations, starting with HELP Committee Chair Dr. Bill Cassidy (R-La.). Cassidy likewise challenged Kennedy during the Senate Finance Committee's confirmation hearing Wednesday.
Cassidy declined to declare support for President Donald Trump's nominee to be the nation's highest-ranking health official during the hearing or when questioned afterward. GOP Sens. Susan Collins (Maine) and Lisa Murkowski (Alaska) also have not declared support for Kennedy.
