A stark divide on vaccine policy exists between President Donald Trump and his controversial pick to lead the Department of Health and Human Services, Robert F. Kennedy Jr., though the president has decided to continue supporting him, a White House official revealed Saturday.

“He doesn't feel as strongly as Bobby on some of these key issues," a White House official told Reuters in a report published Saturday, speaking with the outlet on the condition of anonymity. “He trusts his judgment."

RFK Jr. faced renewed scrutiny this past week following an explosive hearing in the Senate Finance Committee, where for hours, the HHS secretary was grilled by Democratic lawmakers over his controversial stances, including those on vaccines and autism.

On Friday, reporting indicated that HHS would soon release a report linking autism to the use of Tylenol by pregnant women, a claim that has been rebuked by doctors and researchers alike, including in one robust study last year in the Journal of the American Medical Association.

News of the impending report saw shares in Kevue, the drugmaker that manufactures Tylenol, fall by more than 9% Friday, with the drugmaker denying there to be any “causal link” between its drug and autism.

Trump has treaded carefully when discussing vaccines, with many vaccine skeptics among his most vocal supporters. He’s championed Operation Warp Speed, which developed the COVID-19 vaccines, as a success, and has been hesitant to engage with vaccine skepticism, though has floated debunked theories in the past that vaccines cause autism.

"He's a, a very good person... and he means very well, and he's got some little different ideas," Trump said Thursday, shortly after RFK Jr.’s testimony in the Senate Finance Committee. "If you look at what's going on in the world with health, and look at this country also with regard to health, I like the fact that he's different."
