Ohio Rep. Max Miller said he will stay in his reelection race, defying calls from within his own party to withdraw. The Republican faces abuse allegations ahead of an Aug. 5 deadline for ballot replacements.

U.S. Sen. Bernie Moreno, Miller's former father-in-law, publicly called for Miller to step aside before that deadline, which would allow the Republican Party to name a replacement for the November general election.

Miller, seeking a third term, has denied the domestic abuse allegations and has maintained his position to remain on the ballot, setting up a direct confrontation with party leaders.

Aug. 5 marks the final opportunity for the Republican Party to replace Miller on the ballot. If Miller does not withdraw by then, the party loses its chance to field an alternative candidate in the general election.

GOP strategist Doug Heye said party leaders must act quickly if they intend to remove Miller from the ballot.

Miller's refusal to exit pits him against a senior senator from his home state and puts the party's general election strategy in Ohio in question.
