U.S. Senator Jim Banks on Sunday became the latest Republican lawmaker to call for embattled Representative Max Miller to step down, as allegations of physical abuse against his former wife and two-year-old daughter continue to mount.

Appearing on NBC's Meet the Press, Banks, a first-term senator from Indiana, described the allegations — which Miller has firmly denied — as "deeply troubling."

"If the allegations are true and watching this play out publicly, of course he should resign," Banks said.

At least four other Republican senators have already urged Miller to quit, including Bernie Moreno, Miller's former father-in-law. Ohio's other senator, Jon Husted, Montana Senator Tim Sheehy, and Kansas Senator Roger Marshall have all publicly stated that Miller, who represents northeast Ohio, should step aside. Notably, no Republicans serving alongside Miller in the U.S. House have issued similar calls for his resignation.

Banks also warned of political consequences, suggesting that Miller — a Republican seeking a third term — could jeopardize a seat critical to maintaining the GOP's House majority in the November midterms. Republicans are defending a thin House majority this cycle, a margin in which a single scandal-embroiled incumbent can shift the balance of power.

"He should drop out if he's endangering that seat," Banks said.

Miller has maintained that he will not step aside. Last weekend, he released a lengthy video categorically denying each allegation, a move that only intensified public pressure for his withdrawal.

The latest allegations emerged from Miller's divorce proceedings with Emily Moreno. They include claims of physical and emotional abuse of their toddler, throwing hot water at his wife, and other acts of violence. Separately, former White House press secretary Stephanie Grisham, who dated Miller during their time working together at the White House, has accused him of pushing and slapping her.

Miller previously requested a House Ethics Committee probe into the allegations against him, as reported by Bloomberg. The committee has the authority to investigate misconduct by sitting members and can recommend sanctions ranging from a formal reprimand to expulsion, though such inquiries typically take months and often extend beyond an election cycle.

By weathering the criticism past the effective deadline to withdraw from the race, Miller remains on the November ballot. He faces Democrat Brian Poindexter, an ironworker, in the general election.

A spokesperson for Miller did not immediately respond to a request for comment on Sunday. Campaign spokeswoman Abigail Angelos told The New York Times on Saturday that Miller is staying in the race.
