Conservative brawler Lauren Boebert attempted to get “a guy” kicked out of the women’s restroom in the Capitol off the House floor on Thursday. Only problem: It wasn’t a man at all. It turned out to be a case of mistaken identity,

Anti-trans Rep. Lauren Boebert (R-CO) issued a public apology on Thursday after reportedly mistaking a cisgender woman in a U.S. Capitol restroom for out transgender Rep. Sarah McBride (D-DE). She allegedly told the woman, “You shouldn’t be here,” an anonymous Republican representative told The Daily Beast.

The Colorado congresswoman reportedly thought the person was Rep. Sarah McBride, Congress' only transgender lawmaker. She later apologized.
