The House is scheduled to vote on a resolution introduced by Rep. Nancy Mace (R-S.C.) seeking to expel Rep. Cory Mills (R-Fla.) from Congress over allegations of misconduct and misrepresenting his military service record.

Mace's resolution marks a rare instance of a House member attempting to expel a colleague from the same party. The South Carolina congresswoman has accused Mills of providing false information about his military background and engaging in unspecified misconduct.

Expulsion from the House requires a two-thirds majority vote and is considered one of the most severe disciplinary actions Congress can take against a member. Only five House members have been expelled in U.S. history, with three cases occurring during the Civil War for supporting the Confederacy.

Mills, a freshman congressman elected in 2022, previously served in the military and has faced scrutiny over various aspects of his background. The specific allegations regarding his military service representation have not been detailed in the resolution's public summary.

The timing of the expulsion vote has not been announced. House leadership will need to schedule floor time for the resolution, which could face significant procedural and political hurdles given the high threshold required for passage.
