To get confirmed as HHS secretary, President-elect Donald Trump’s pick Robert F. Kennedy Jr. will first need to get through the Senate Finance Committee.

And though Republicans will have an edge, it will take only a few defectors to sink his nomination if Democrats, as expected, oppose him in unison. Republicans have rushed to applaud some of Trump’s more conventional other Cabinet picks, but the lack of public enthusiasm for RFK among some on the committee suggests some may be skeptical.

Here’s where committee Republicans stand on Kennedy, so far:

Mike Crapo, Idaho: The top Republican on the committee said in a statement that Kennedy has “prioritized addressing chronic diseases through consumer choice and healthy lifestyle. American patients, providers and taxpayers deserve a health care system that is efficient, effective and affordable. I look forward to considering his nomination before the Finance Committee.”

Crapo attended a recent roundtable hosted by Sen. Ron Johnson (R-Wisc.) and Kennedy that focused on the dangers of processed foods and alternative diets. Crapo has said his nascent interest in “healthy eating” led him to attend the event and was supportive of much of what was discussed. However, before Kennedy was chosen, Crapo said he doesn’t know if Kennedy could win enough support in the Senate to be confirmed.

Chuck Grassley, Iowa: A spokesperson for the senator declined to comment. In an interview with AgriTalk Radio in October, however, Grassley said there are ways to “make America Healthy Again” without “upsetting the way we produce food.”

“Whatever ideas he has about making lives … more healthy, it’s got to be compromised with producing enough food so everyone doesn’t die,” Grassley said.

John Cornyn, Texas: Cornyn, who was the runner-up in the race for Senate majority leader, said Kennedy will be treated like all other nominees.

“I don’t have any preconceived notion about it,” Cornyn said. When asked whether vaccine positions might make confirmation difficult: “I’m sure it will come up.”

John Thune, South Dakota: The incoming Senate majority leader said he won’t make judgments on any nominees “at this point.”

“There’s a confirmation process that we have to adhere to,” Thune said. “Constitutionally, there are committees that are going to be conducting hearings and there’ll be plenty of scrutiny of these nominees’ records when the time comes.”

Tim Scott, South Carolina: A spokesperson for Scott declined to comment. But before the election, Scott deflected when asked by CNN’s Dana Bash about Kennedy’s plans to remove fluoride from public water. He said then that he doesn’t have a personal relationship with Kennedy but is confident that the administration will choose “competent” and “qualified” nominees.

Scott introduced legislation with fellow Finance Committee member Bill Cassidy (R-La.) in 2018 backing water fluoridation.

Bill Cassidy, Louisiana: Cassidy, who will chair the Senate HELP Committee, expressed openness to Kennedy in a statement.

“RFK Jr. has championed issues like healthy foods and the need for greater transparency in our public health infrastructure,” Cassidy said. “I look forward to learning more about his other policy positions and how they will support a conservative, pro-American agenda.”

Todd Young, Indiana: A spokesperson for Young — who said he would not support Trump in 2024 — declined to comment.

John Barrasso, Wyoming: A spokesperson for Barrasso didn’t return a request for comment. But in an interview with NBC News before Kennedy was selected, Barrasso said Trump should have the latitude to make picks and declined to weigh in on Kennedy.

Ron Johnson, Wisconsin: Johnson praised Kennedy in a post on X.

“I could not be happier that [Trump] has selected [Kennedy],” Johnson wrote. “He’s a brilliant, courageous truth-teller whose unwavering commitment to transparency will make America a healthier nation.”

Marsha Blackburn, Tennessee: Blackburn supported the pick in a post on X.

“[Kennedy] will honor his commitment to put the health of Americans first. Another great choice by President Trump,” Blackburn wrote.

Others: Spokespeople for Republican Sens. James Lankford of Oklahoma, Steve Daines of Montana and Thom Tillis of North Carolina did not respond to requests for comment.
