South Carolina Republican Nancy Mace has lashed out at one of her Capitol Hill colleagues who is seeking to give her a taste of her own medicine.

On Monday, Mace introduced a resolution to expel Florida Republican Cory Mills from the US House of Representatives.

Mills then retaliated, filing a resolution to expel Mace.

Mace noted in a Monday post on X that '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.'

'He is neck-deep in fraud and police reports. He has no place in Congress. His rightful place is behind bars,' Mace added in her statement, before urging Mills to 'bring it on.'

In a 2025 police report, Mills was accused by his then-girlfriend of grabbing her, shoving her, and pushing her out of the door of his apartment. Mills has denied the accusation, saying the woman's original allegation was 'patently false.'

Mace herself has been accused of being a difficult boss and mistreating her own staff.

A New York Magazine report released earlier this year detailed accounts from former staffers, including one who claimed: 'Our poor scheduler was getting calls at two in the morning to bring her bottles of tequila.'

Alcohol was not the only substance Mace allegedly used, with multiple staffers also noting her cannabis use, described by some as 'excessive.'

Mills also jabbed at Mace on X on Tuesday morning, posting pictures of Mace drinking alcohol along with a claim from her that she has a condition that means that she can't drink. 

Another staffer claimed they were allegedly instructed by Mace to look up forums on the social media site Reddit that ranked the 'hottest women in Congress' and to raise her standing with comments and 'upvotes.'

Ahead of the story's publication, Mace went on offense, taking the 'hit piece' as a badge of honor.

'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,' Mace stated in a Sunday evening post to her X account.

'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,' Mace also argued in her own defense.

Mace was also filmed having a heated altercation with Charleston airport staff back in her home state of South Carolina, where she is presently running for Governor.

The bipartisan House Ethics Committee formed a subcommittee to investigate a wide range of claims against Mills. The inquiry remains ongoing.

'I don't belong in the same category as Swalwell and his allies,' Mills told NewsNation last week.

'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,' the Florida Republican said. He said the ordeal is 'obviously a political, Democratic tit-for-tat.'

It is unclear if Mills' divorce is finalized; it was reported in September 2025 that he was still undergoing legal proceedings. A former Mills staffer told the Daily Mail they were unsure if the divorce agreement had been completed.

Earlier this month, Mills' longtime chief of staff and chief counsel, Catherine Treadwell, abruptly resigned.

In her resignation letter she thanked her co-workers and concluded it with an ominous message: 'The horrors persist, but I do not.'

There is a high bar to expel members of the House. 

Two-thirds of the members must vote to boot anyone from the body. Only six members of the House have ever been expelled, the most recent being former New York Congressman George Santos in 2023.
