The top strategist for the embattled super PAC backing Florida Gov. Ron DeSantis ’ campaign for the White House resigned Saturday night in the latest sign of trouble for the GOP hopeful less than one month before voting begins with Iowa’s kickoff caucuses.

Jeff Roe, the top adviser to Never Back Down, is the latest senior staffer to exit Never Back Down, which has been the largest outside group supporting DeSantis’ candidacy.

He announced his departure on X, the site formerly known as Twitter, hours after The Washington Post published a story focused on internal disputes and suspicions between Never Back Down, the campaign, and other DeSantis allies that included accusations of “mismanagement and conduct issues, including numerous unauthorized leaks containing false information.”

“I can’t believe it ended this way,” Roe wrote on X, sharing a statement in which he said he “cannot in good conscience stay affiliated with Never Back Down given the statements” in the story, which he said were false.
