Fissures within the House Republican conference are surfacing on the midterm campaign trail, with several lawmakers facing misconduct allegations that could jeopardize the party's grip on Congress. Among them, Rep. Cory Mills, R-Fla., is embroiled in a contentious primary fight and faces multiple investigations.

Two Florida House Republicans, Reps. Mike Haridopolos and Anna Paulina Luna, have publicly endorsed Ryan Elijah, a primary challenger to incumbent Rep. Cory Mills. They urged fellow Republicans to support Elijah, with Haridopolos stating that Elijah "will ensure victory for us in Florida 7." This endorsement comes despite President Donald Trump's backing of Mills for re-election.

A source familiar with the situation indicated to Fox News Digital that some Florida Republicans are concerned about their ability to retain Mills' seat if he wins the upcoming primary. The Cook Political Report has already adjusted its projection for the district from "Solid R" to "Likely R," suggesting it could be a competitive race in November.

Mills is reportedly under investigation by both the House Ethics Committee and the Department of Justice (DOJ). He has consistently denied any wrongdoing, dismissing reports of a DOJ investigation as a "desperate lie" from his opponents. Mills stated on social media that his office is unaware of any DOJ investigation and would cooperate if one were initiated.

Mills is not the only House Republican facing scrutiny. Rep. Chuck Edwards, R-N.C., withdrew from his re-election campaign following a report detailing sexual harassment accusations from two former staffers. Edwards has denied the accusations but acknowledged making staff feel uncomfortable at times.

Additionally, Rep. Max Miller, R-Ohio, is facing accusations of domestic abuse from his ex-wife and former father-in-law, Sen. Bernie Moreno. According to one House GOP source, these situations are creating significant challenges for the party. Miller has denied the allegations and has asked the House Ethics Committee to investigate in order to clear his name, resisting calls to drop out of his race.

All three seats held by Mills, Edwards, and Miller are reportedly on the Democratic Congressional Campaign Committee's target list, indicating that Democrats are investing resources into these races. One House Republican, speaking anonymously, suggested that all three lawmakers should step aside to "lead by example."
