Cory Mills

Representative Cory Mills of Florida is running for re-election in a solidly Republican district and has President Trump’s endorsement. Yet two of his fellow Republicans on Florida’s congressional delegation would prefer he lose his upcoming primary election.

Representatives Anna Paulina Luna and Mike Haridopolos took the rare step of endorsing one of Mr. Mills’s rivals this week, underscoring how vulnerable some Republicans consider Mr. Mills, who was investigated by the police in Washington, D.C., last year after a woman filed a report of assault. No charges resulted.

His former girlfriend was also granted a protective order against him. As a result of the various examinations, the House Ethics Committee is also investigating.

Mr. Mills has denied wrongdoing. But he has struggled to raise money, and Democrats have targeted his seat northeast of Orlando, which Mr. Trump won by 22 percentage points in 2024.

Ms. Luna and Mr. Haridopolos endorsed Ryan Elijah, a former local Fox television news anchor, who is one of three Republicans challenging Mr. Mills in the Aug. 18 primary.

“We need leaders in Congress who serve with integrity, energy, and an unwavering commitment to the people who sent them there,” they wrote in a joint statement on Wednesday.
