Two analysts say that one politician who has "a cult of his own" represents the biggest threat to President Donald Trump.

Former Republican strategist Rick Wilson and journalist Molly Jong-Fast posited that Trump is afraid of Robert F. Kennedy Jr., his secretary of Health and Human Services, in a live Substack video chat on Wednesday.

"I believe the biggest threat to Trump, and I think Trump knows this, is RFK Jr. Because RFK Jr. has his own constituency," Jong-Fast said.

Others in Trump's inner circle don't actually have a similar following, she argued.

"He has a cult of his own. Whereas no one else does. Everyone else is just trying to out-Trump Trump. Yeah, I don't think there is anybody else in that circle that has the same level of fanaticism that RFK has built," Jong-Fast said.

"And also, RFK wants it," she explained, describing his persistent messaging around autism and Tylenol and suggesting mothers are to blame, plus his anti-vaccine messaging (despite himself and his family getting vaccinated) and "straightforward narrative that appeals to the conspiratorial nature of MAGA. 'I'm going to make sure the food people and the drug people don't poison your children.'"
