Representative Max Miller (R-OH), a former Trump White House aide who first won his House seat in 2022, is facing mounting pressure to resign from Congress — including from his ex-wife's father, U.S. Senator Bernie Moreno (R-OH) — after denying allegations that he threw boiling water at his former wife, Emily Moreno, and broke their toddler daughter's collarbone.

Miller, who is seeking re-election, has refused to withdraw from his campaign. On Sunday morning, he posted a 20-minute video on X categorically denying the claims against him.

"It was horseplay in our kitchen," Miller said, referring to the boiling water incident. He also pointed to Emily Moreno's one-time offer to make him empanadas as evidence that their relationship was not abusive.

The congressman noted that no criminal charges have been filed against him and that Child Protective Services had found all accusations leveled against him to be unsubstantiated. He shared a collection of documents that he argued supported his denials.

Sen. Moreno, who was elected to the Senate in 2024 and had been notably silent on his daughter's abuse claims, broke his silence following Miller's video. He was not persuaded by the congressman's defense. The public break between the two Ohio Republicans — linked by both party and family ties — marks an unusually personal instance of a sitting senator calling for a House colleague of the same party to step down.

"He is a danger to my daughter, and I hold my breath every minute he has custody of my granddaughter," Sen. Moreno wrote on X. "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 also stated that Miller himself had admitted to needing "serious psychological help."

The Ohio senator was not the only public figure to express dismay and call for Miller's resignation. Journalist Sam Stein reported on Moreno's position, commenting: "Credit where due. He got there."

Democratic strategist Ally Sammarco highlighted Moreno's assertion about Miller needing psychological care. "Important: Bernie Moreno says that Max Miller, himself, has admitted that he needs 'serious psychological help,'" Sammarco wrote. "Resign, you freak."

Former Republican Representative Adam Kinzinger also weighed in. "I'd call for more than 'psychological help,'" Kinzinger said. "That said, Miller needs to leave."

The growing calls add uncertainty to Miller's re-election bid and raise the question of whether House Republican leadership will publicly address the matter. The allegations against Miller were previously detailed in a New York Times report published July 28.
