Moreno, who has been publicly restrained in recent months as the bitter custody dispute has played out between Miller and his daughter Emily, said in a lengthy post: “If there are any basic standards of character required to hold elected office, Max Miller fails them. He should not serve in the House of Representatives.”

Moreno wrote that Miller “needs serious psychological help. He is a danger to my daughter, and I hold my breath every minute he has custody of my granddaughter.”

Miller said Sunday that he will remain in his race for reelection before a Wednesday deadline to replace him. Democrats have seen a new opportunity in his northeast Ohio congressional seat as the Republican incumbent has faced mounting pressure over the domestic abuse allegations in a bitter and drawn-out custody battle with his ex wife.

“I’m not dropping out of this race and I’ll win in November,” said Miller, who denied abusing his former wife and his daughter.

Custody dispute has escalated in recent weeks

Accusations against Miller, who has been endorsed by President Donald Trump and was a White House adviser during Trump’s first term, have been public for years but have recently drawn increased scrutiny as back and forth in the case has escalated.

Emily Moreno has said that Miller scalded, hit and threatened her while they were married. Miller denied those allegations in the video, as he has in the past.

“It’s incredibly upsetting,” Miller said, as he went through a list of the allegations.

Miller also said he had nothing to do with a broken collarbone on their 2-year-old daughter that led Emily Moreno to contact authorities. The pair, who were married in 2022 and finalized their divorce last year, have presented different theories about how the injury occurred, according to court filings and police reports detailed in an article in the magazine Mother Jones that first revealed the child’s injury.

Miller accompanied his announcement with the release of a voluminous cache of investigative and court documents related to the custody dispute.

Spokesperson for Miller’s ex wife says video was ‘shameful’

A spokesperson for Emily Moreno, Stefan Mychajliw, said Sunday that the video was “shameful.”

“No loving parent would have ever used their daughter as a PR pawn to save their own political career,” Mychajliw said. “Miller can lie and spin on X, but he cannot do so under oath in a court of law. We are confident that justice will prevail in court.”

Sen. Bernie Moreno’s statement on Sunday came after he had declined to comment on the specific allegations for months. Last week, a spokeswoman issued a statement saying the senator “will not litigate these matters in the media or respond to baseless public attacks.”

“Senator Moreno’s top priority is the safety and well-being of his daughter and granddaughter,” said the spokeswoman, Reagan McCarthy.

Potential GOP candidates eye Miller’s seat

The senator’s statement was prompting some hand-wringing behind the scenes in his home state, where Trump-endorsed candidates like Miller typically win with ease.

State Rep. Mike Dovilla, a U.S. Navy veteran and former presidential appointee to the Office of Personnel Management, and Kevin Coughlin, a former state senator and representative who ran for the U.S. House in 2024 and 2026, were among Republicans whose names were being floated should Miller drop his fall House bid, according to a high-ranking Republican who discussed the sensitive subject on condition of anonymity.

Democrats have recently called on Miller to resign, requested a congressional ethics investigation and suggested more help could be directed in the fall toward his Democratic opponent, union ironworker Brian Poindexter.

Miller won reelection two years ago with just over 51% of the vote.
