Two Florida House Republicans have endorsed a primary challenger to Rep. Cory Mills, deepening a public rift within the state's GOP delegation as the party tries to defend its narrow House majority ahead of the 2026 midterms. The move reflects growing unease among Mills' colleagues over allegations swirling around him, and highlights broader divisions within the House Republican conference as the party fights an uphill battle to hold Congress for the second half of President Donald Trump's term.

Mills is facing multiple allegations, and has publicly denied a reported Justice Department investigation into him, claiming instead that a Florida Republican primary rival is behind the story. The endorsement of his opponent by fellow GOP House members marks an unusually direct intervention by sitting Republicans in a colleague's primary race, underscoring how seriously some in the party view the controversy surrounding him.
