Fetterman says RFK Jr confirmation 'not a slam dunk,' as Trump HHS nominee shores up support

Asked if he's reached a decision on whether he'll vote "yay" or "nay" for Kennedy, Fetterman said he has spoken to colleagues on both sides regarding the matter. 

"It's been challenging for sure. Absolutely. It's certainly not a slam dunk for the nomination," Fetterman told "Fox News Sunday" host Shannon Bream. "I've made an investment to really understand and talk to all of the nominees, and I treated everyone with respect and I took the time to listen, and that's been part of my commitment," he added.

Most of the tough questions and sparring over his stances on vaccines, abortion, Medicaid and other issues came from Democrats on the two committees, but Thursday's hearing ended with the top Republican on the Health panel saying he was "struggling" with Kennedy's nomination.

"Your past of undermining confidence in vaccines with unfounded or misleading arguments concerns me," Sen. Bill Cassidy, R-La., told the nominee.

The physician from Louisiana, who is a crucial vote and who has voiced concerns over Kennedy's past stance on vaccines, asked whether Kennedy can "be trusted to support the best public health." The senator told Kennedy, who seeks to lead key health agencies like the Centers for Disease Control and Prevention, the Food and Drug Administration, the National Institutes of Health and the Centers for Medicare and Medicaid Services, that "you may be hearing from me over the weekend."

Kennedy, whose outspoken views on the pharmaceutical and food industries have also sparked controversy, has said he aims to shift the focus of the agencies he would oversee toward promotion of a healthy lifestyle, including overhauling dietary guidelines, taking aim at ultra-processed foods and getting to the root causes of chronic diseases.
