The House Ethics Committee has announced it is opening an investigation into Rep. Max Miller, after the Ohio Republican asked the committee for a probe of the domestic abuse allegations that have swirled around his bid for reelection.

The panel made the announcement on Tuesday, saying it was reviewing allegations that Miller “may have engaged in domestic violence and abuse or illegal drug use” in violation of congressional codes of conduct.

“The Committee notes that the mere fact that it is investigating these allegations, and publicly disclosing its review, does not itself indicate that any violation has occurred,” it said in a statement.

Earlier on Tuesday, Miller announced on social media he planned to ask the committee to look into the allegations.

“In light of all the renewed interest in my family affairs I am going to file my own paperwork for an ethics investigation into myself to clear my name from these horrific attacks on myself and family. I have absolutely nothing to hide,” he wrote.

Miller, who is seeking a third term in the House, has been locked in an acrimonious and public custody battle with his ex-wife, Emily Moreno, who is the daughter of Sen. Bernie Moreno, R-Ohio.

Moreno filed for divorce from Miller in 2024 after two years of marriage, with Moreno accusing Miller of violent and abusive behavior. According to court records filed earlier this year, she has alleged that Moreno scalded her by throwing hot water at her body, pushed her against a wall, and even once held a gun to her head. She also says he fractured their young daughter’s collarbone.

Miller has denied the allegations, saying in a video posted to social media over the weekend that he has never been physically abusive toward Moreno. He denied ever holding a gun to her head and discussed the water incident as “horseplay” with water from a kitchen sink hose.
