Rep. Nancy Mace, R-S.C., filed a motion to expel Rep. Cory Mills, R-Fla., from the House of Representatives on Monday evening, setting up a rare expulsion vote that will test whether Congress is willing to remove one of its own members.
The resolution, first obtained by Fox News Digital, accuses Mills of misrepresenting his military service, sexual misconduct, campaign finance violations and illicit involvement in federal contracts during his time in Congress.
The expulsion push comes after NOTUS reported that Mills was simultaneously drafting a similar resolution to remove Mace from the chamber. "As a survivor, I will always stand up and right the wrongs of others," Mace wrote on social media. "He is only coming after me because he knows he's next."
Mace is currently running for governor of South Carolina. Mills, who is seeking a third House term in November, has received President Donald Trump's endorsement for re-election.
What the Right Is Saying
House Republican leadership has continued to stand by Mills despite the mounting allegations. Speaker Mike Johnson, R-La., has urged lawmakers to let Ethics Committee proceedings run their course before taking punitive measures.
"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," Rep. Anna Paulina Luna, R-Fla., told Fox News Digital last week when asked about whether she would support expelling Mills.
Many Republicans have expressed concern about the allegations but stopped short of calling for expulsion. Some GOP members have noted that Mills has denied any wrongdoing and has not been criminally charged, arguing that due process should be allowed to proceed.
The party's leadership has emphasized that the Ethics Committee investigation, which began in November 2025, should be allowed to reach its conclusions before Congress takes any action.
What the Left Is Saying
Progressive Democrats and progressive advocacy groups have largely welcomed the expulsion effort, though they note that Mace's move comes as part of a broader pattern of Republican infighting. Some progressive commentators have pointed out that the allegations against Mills, including accusations of sexual misconduct and domestic violence, mirror patterns seen in other scandals that have plagued the party.
Democratic lawmakers have been cautious about directly weighing in on the Republican intraparty dispute. However, several Democrats have noted that the expulsion proceedings highlight what they describe as a pattern of alleged misconduct among certain Republican members.
The focus on accountability has resonance with progressive voters who have long advocated for stronger ethical standards in Congress, particularly following high-profile scandals involving members of both parties.
What the Numbers Show
Expelling a member of Congress requires a two-thirds supermajority vote in the House — meaning 290 of 435 members would need to vote for removal. This high threshold has made successful expulsions extremely rare in American history.
The House Ethics Committee investigation into Mills, which began in November 2025, is ongoing and involves allegations of "sexual misconduct and/or dating violence," according to a committee statement. The panel has not specified when it expects to conclude its inquiry.
In November 2025, Mace's effort to censure Mills and strip him of two committee assignments was overwhelmingly rejected. More than 300 lawmakers voted to send the matter to the Ethics Committee instead of taking immediate action.
Mills has not been criminally charged. He is facing an ex-girlfriend's allegation that he threatened her with revenge porn after they broke up, and a separate assault allegation that prompted a law enforcement response in Washington, D.C., last year.
The Bottom Line
The upcoming expulsion vote represents an extraordinary moment in House politics, with two sitting Republican lawmakers seeking to remove each other from Congress. Whether Mace's resolution can clear the two-thirds threshold remains highly uncertain, particularly given Republican leadership's stance of waiting for the Ethics Committee process to conclude.
The mutual expulsion efforts underscore the escalating tensions within the Republican conference ahead of the 2026 midterm elections. Both Mace, who is running for South Carolina governor, and Mills, who faces a competitive re-election bid, have significant political stakes riding on the outcome.
The House Ethics Committee's ongoing investigation into Mills will likely factor heavily into how lawmakers vote. Observers will be watching to see whether the panel issues its recommendations before the expulsion vote occurs, and whether those recommendations influence the outcome.
