Rep. Nancy Mace introduced a resolution Monday to expel fellow Republican Cory Mills from the U.S. House, accusing the Florida congressman of domestic violence, arms dealing, stolen valor, and profiting off federal contracts from his seat. Hours later, Mills filed his own expulsion resolution targeting Mace, turning an intra-party feud into one of the most unusual standoffs on Capitol Hill in years.
Neither resolution is likely to succeed. Expelling a sitting member requires a two-thirds vote, a threshold reached only six times in the history of the House. But the dueling filings expose a raw, public fracture inside the Republican conference at a moment when the party can afford few distractions and fewer lost seats.
The clash matters less for its legislative odds than for what it reveals: two GOP members willing to torch each other's reputations on the public record, each daring the other to blink first.
Mace laid out her allegations in blunt terms on X. As the Daily Mail reported, the South Carolina Republican wrote:
"Mills allegedly beats women, has a restraining order against him from threatening a woman, reports say he's an arms dealer while sitting on House Armed Services and Foreign Affairs, and rumored to be profiting off federal contracts from his own seat."
She followed that with a sharper post: "He is neck-deep in fraud and police reports. He has no place in Congress. His rightful place is behind bars."
A 2025 police report cited in coverage accused Mills of grabbing his then-girlfriend, shoving her, and pushing her out the door of his apartment. Mills has called the accusation "patently false." He has not been criminally charged.
Mace's resolution also accuses Mills of misrepresenting his military service, a stolen valor allegation, and of campaign finance violations. Just The News reported that the resolution was not filed as privileged, meaning it does not automatically force a floor vote, though Mace could move to compel one later.
On social media Monday, Mace framed the fight in personal terms. "As a survivor, I will always stand up and right the wrongs of others," she wrote, as Fox News reported. "He is only coming after me because he knows he's next."
She also told critics to "bring it on."
Mills wasted no time retaliating. He filed his own expulsion resolution against Mace and took to X on Tuesday morning, posting pictures of Mace drinking alcohol, an apparent jab at claims she has a medical condition that prevents her from drinking.
In a Newsmax report on the confrontation, House Speaker Mike Johnson was noted as saying the chamber should wait for the House Ethics Committee to finish its investigation before taking action on either member.
Mills told NewsNation last week that the whole episode was "obviously a political, Democratic tit-for-tat." He rejected comparisons to other members who have faced ethics scandals:
"I don't belong in the same category as Swalwell and his allies. One, I'm not married, so there's one thing. Two, I've never sexually harassed and or have any complaints by any staffers or interns on the Hill. It's just not even a fair comparison."
That defense may face a tougher audience soon. The bipartisan House Ethics Committee formed a subcommittee to investigate a wide range of claims against Mills. That inquiry, which the New York Post reported has been underway since November, remains ongoing.
If Mills faces serious allegations, Mace is hardly operating from a position of untouchable credibility. A New York Magazine report published earlier this year detailed accounts from former staffers painting an unflattering picture of the South Carolina congresswoman's conduct.
One former staffer claimed: "Our poor scheduler was getting calls at two in the morning to bring her bottles of tequila." Multiple former staffers noted what they described as "excessive" cannabis use. Another staffer alleged Mace instructed them to search Reddit forums ranking the "hottest women in Congress" and to boost her standing with comments and "upvotes."
Mace was also filmed having a heated altercation with staff at the Charleston airport in her home state. The incident added to a pattern of public confrontations that have drawn scrutiny even from allies.
Mace preemptively addressed the New York Magazine piece on Sunday evening, posting on X: "As NY Mag publishes the next national hit piece against me tomorrow, the establishment doesn't go after people who fall in line. They go after people who don't." She added: "I'll take that as a compliment. When you stand for something, you make enemies. I've never let that stop me from doing my job, and I'm not starting now."
The episode is only the latest in a string of intra-Republican confrontations that have consumed House floor time and leadership bandwidth this session.
Mills' internal troubles extend beyond the expulsion fight. His longtime chief of staff and chief counsel, Catherine Treadwell, abruptly resigned earlier this month. In a resignation letter thanking co-workers, Treadwell offered a memorable parting line: "The horrors persist, but I do not."
The departure of a senior staffer under those terms rarely signals smooth operations. It also undercuts Mills' claim that no staffers or interns have raised complaints about his conduct on the Hill.
As of September 2025, Mills was also still undergoing legal proceedings in his divorce. Whether those proceedings are finalized remains unclear.
Only six House members have ever been expelled. The most recent was former New York Congressman George Santos in 2023, after a lengthy ethics investigation and federal indictment. The two-thirds requirement makes expulsion nearly impossible without bipartisan consensus, or a scandal so severe that a member's own party abandons them.
Neither Mace nor Mills appears close to that threshold. But the resolutions serve a purpose beyond the vote count. They put allegations on the congressional record. They force colleagues to take a public position. And they create pressure that can push a member toward resignation, as other lawmakers have discovered in recent months.
Rep. Anna Paulina Luna told Fox News Digital: "If there's evidence of criminal misconduct and wrongdoing, I hold the same standard for every member of Congress, whether they're a Democrat or Republican." That standard, applied evenly, would leave both Mace and Mills with questions to answer.
The broader context is hard to ignore. The House has dealt with a wave of ethics scandals across party lines. Rep. Sheila Cherfilus-McCormick resigned minutes before an ethics panel was set to recommend her expulsion. Other members have faced similar pressure.
Breitbart noted that Mace's earlier efforts to censure Mills and strip him of committee assignments were blocked by members of both parties, which prompted her escalation to the expulsion resolution. "The swamp has protected Cory Mills for far too long and we are done letting it slide," Mace wrote on X.
Mace is also running for governor of South Carolina, a campaign that gives her every incentive to stay in the headlines, and to project the image of a fighter willing to take on her own party's establishment. Whether the expulsion push is principled accountability or campaign-trail positioning is a question voters will have to sort out.
Meanwhile, the recent demand that Rep. Tony Gonzales resign over separate allegations shows the GOP conference is not short on internal conflicts requiring leadership attention.
The Ethics Committee investigation into Mills continues. Mace could force a floor vote on her resolution at any time, though doing so without leadership support would likely result in defeat. Mills' retaliatory resolution faces the same math.
Speaker Johnson's preference to wait for the Ethics Committee report suggests leadership wants to contain the damage, not accelerate it. But containment only works if both sides cooperate, and neither Mace nor Mills has shown any interest in standing down.
The open questions are substantial. What exactly does the Ethics Committee's subcommittee have? Will criminal charges follow the 2025 police report? And can the Republican conference afford to let two of its members spend the summer publicly savaging each other while the party's legislative agenda hangs on a razor-thin majority?
Voters in South Carolina and Florida didn't send their representatives to Washington to watch them file dueling expulsion resolutions on social media. Absent members and distracted ones both cost the conference the same thing: focus.
If the allegations against Mills are as serious as Mace claims, the Ethics Committee should move faster. If they aren't, Mace owes an explanation for the spectacle. Either way, the people paying the price for this circus are the constituents who expected their representatives to govern.
