A public rift within Ohio's Republican Party has erupted after Senator Bernie Moreno called on Congressman Max Miller, his former son-in-law, to resign, accusing him of abusive behaviour and claiming he presents a danger to Moreno's daughter and granddaughter. The extraordinary intervention, posted on X on Sunday, marks the sharpest escalation yet in a long-running family dispute that has now spilled out of private life and into national politics, drawing attention to tensions among senior Ohio Republicans.

Moreno urged Miller to step down from the House and seek "serious psychological help," while Miller has firmly denied the allegations, stating that investigations found no evidence he harmed his daughter. Miller has accused his former wife, who is Moreno's daughter, and the media of promoting a false narrative against him, and has vowed to remain in his congressional race despite the mounting pressure from within his own party.
