Domestic abuse allegations against Republican Representative Max Miller of Ohio have prompted Democratic calls for a House ethics investigation and a resignation demand from a prominent anti-gun violence group. The allegations, detailed in a July 30, 2026 Guardian report, stem from two women: Miller's ex-wife, conservative policy adviser Emily Moreno, and former girlfriend Stephanie Grisham, who served as White House press secretary during Donald Trump's first administration.

Miller, 37, represents Ohio's seventh congressional district and is actively campaigning for re-election. The escalation of allegations and counter-lawsuits introduces significant volatility into his race and draws two politically connected figures into the open.

Moreno and Miller married in 2022, share a two-year-old daughter, and have been locked in a custody legal battle since 2024. Earlier in 2026, amid a defamation lawsuit Miller filed against her, Moreno testified that Miller threw hot water from an egg-cooking pan at her. She also accused him of holding a gun to her head, a claim first reported by the New York Times on July 28 under the headline 'Domestic Abuse Allegations Rock an Ohio House Race.' The allegations also include claims that Miller possibly injured their child, as noted in a July 30 Mother Jones report detailing the Democratic push for an ethics probe.

In June 2026, Miller told Spectrum News that the allegations were false. He stated his divorce was finalized on December 18, 2025, and noted that no police reports were ever filed.

Grisham, who dated Miller from 2019 to 2020, wrote about an abusive relationship with a former partner in an October 5, 2021 Washington Post op-ed without naming him at the time, but later confirmed she was referring to Miller. Miller sued Grisham for defamation but later dropped the lawsuit as part of a confidential settlement agreement. Grisham has since filed a new lawsuit against Miller alleging he violated the settlement through comments he made to Spectrum News, according to the Guardian. Cleveland.com and the Ohio Capital Journal both reported on the settlement breach lawsuit in July 2026.

The conflict also involves Senator Bernie Moreno, Emily Moreno's father and the Republican US Senator for Ohio. In May 2026, Miller posted on X that the senator 'continues to fund and enable his daughter's malicious campaign to ruin my life.' Bernie Moreno's spokesperson told the Guardian that the senator's top priority is the safety and well-being of his daughter and granddaughter, and that he will not litigate these matters in the media.

A prominent anti-gun violence group called for Miller's resignation following the allegation involving a firearm. The Guardian reported the call without specifying the group's internal membership size or political leverage.

The structure of these claims requires separating what is documented from what is alleged. The absence of police reports limits the evidentiary record to civil filings, sworn testimony, and public statements.

Looking at what this means for the institutional dynamics: the convergence of a custody dispute, multiple defamation lawsuits, and a confidential settlement creates a dense evidentiary trail that an ethics committee would need to parse. The involvement of Grisham, who broke with Trump, and Moreno, whose father is a sitting US Senator, complicates the political landscape.

The new Grisham lawsuit regarding the settlement violation, if litigated, risks unsealing details typically shielded by confidentiality agreements. The core tension rests on verifiable court documents against contested personal accounts. The Guardian article synthesizes prior reporting from the New York Times and Spectrum News, confirming the layered nature of the disclosures. With Miller's re-election campaign active, the primary consequence is the legal liability from the pending lawsuit and the political accountability from the ethics investigation call.
