Keep this in mind for when the orange guy speaks this week.
A presidential announcement that Senators are “illegitimate” (even if citing alleged fraud) would be political or rhetorical at most. It has no legal force to unseat them.
Challenges to elections or qualifications are handled through the Senate’s own processes (or courts in some pre-seating disputes).
Post-seating, after certification and years of service, removal is exceptionally rare and always requires Senate action.
Historical examples of Senate expulsions or invalidations of seats (e.g., during the Civil War era or the 1912 Lorimer case involving bribery) were decided internally by the Senate itself—not by presidential decree.
In short, the separation of powers prevents the executive branch from overriding the Senate’s judgment over its own membership. Any effort to address alleged election issues in Georgia (or elsewhere) would need to go through the Senate, courts, or other established legal channels—not a unilateral presidential statement.
