Rep. Nancy Mace, R-S.C., introduced a bill on Monday that would prohibit members, officers and employees of the House who are biological males, including transgender women, from using female facilities in the Capitol or House office buildings.

Rep.-elect Sarah McBride, D-Del., recently became the first openly transgender person elected to Congress and is male.

Under the bill, the House sergeant-at-arms, William McFarland, would be in charge of enforcing the ban, which prohibits access to single-sex facilities except those "corresponding to the biological sex of such individual" using them.

"Biological men do not belong in private women’s spaces. Period. Full stop. End of story," Mace wrote on X.
