The House Ethics Committee has started an investigation into Rep. Max Miller, an Ohio Republican. The committee wants to find out whether he committed domestic violence or abuse, or used illegal drugs, according to a press release dated August 4, 2026.

The Ethics Committee is a group of lawmakers from both parties that looks into accusations of misconduct by members of the House. The committee announced the review in a joint statement from its chairman and ranking member. NPR reported the story the next morning on Morning Edition, with reporting by Steve Inskeep. NPR

Miller actually asked the committee to investigate the abuse allegations, which have surrounded his reelection campaign, according to NPR. The allegations that Miller abused his ex-wife and their young child came up in recent legal filings, CBS News reported. CBS News

Miller has denied the allegations. The National Desk and KYUK both reported his denial on August 4.

The review covers three things: whether Miller engaged in domestic violence, whether he committed abuse, and whether he used illegal drugs, according to The Hill and The National Desk. The committee's statement did not give details about the evidence behind each question. The Hill

Miller faces growing calls to end his reelection campaign as the allegations have spread, ABC30 reported. The precise sources of those calls were not specified in the available reporting.

The committee said in its statement that just because it is reviewing the matter does not mean any rules were broken. This is standard language the committee uses when it opens a review.

The allegations came from legal filings tied to a custody dispute, according to CBS News. The National Desk also described the matter as connected to a custody battle. The specifics of those filings, including when and where they were filed, were not detailed in the available reporting. The National Desk

Miller represents Ohio's 7th Congressional District and is running for reelection. The investigation will happen while he campaigns, so voters will hear about it as they decide whether to support him.

The committee has not said when it will finish. These investigations can take months. The committee can also create a special subcommittee to dig deeper if needed. The August 4 press release said only that the review is ongoing.

The broader context here is that the Ethics Committee has been busy with several cases lately. The panel decided to handle this review directly rather than sending it to a separate office that does early checks on misconduct claims. That choice suggests committee leaders felt the allegations were serious enough to act on themselves. But that decision is not a finding of wrongdoing, and the committee says the investigation could end with no violation found.

For House Republicans, the situation brings some uncertainty. Miller's seat is not currently rated as competitively at-risk in the available reporting. But an open ethics investigation during campaign season creates a question party leaders will have to manage. If more people call for Miller to drop out, Republican leaders would face a choice about whether to speak publicly before the committee finishes its work.

Miller's choice to request the probe himself is worth noting. Lawmakers who send their own cases to the Ethics Committee usually do it to get the matter into a formal process with set rules and confidentiality. Think of it like asking a referee to review a play rather than leaving the call to the crowd. Whether that approach works depends on how long the investigation takes and what it finds.
