Rep. Nancy Mace (R-SC) introduced a bill on Monday that would force “members, officers, and employees of the House” to use bathrooms that are in line with their birth sex.

The bill noted that “allowing biological males into single-sex facilities, such as restrooms, locker rooms, and changing rooms designed for women, jeopardizes the safety and dignity of Members, officers, and employees of the House who are female.”

The House Sergeant-at-Arms would be responsible for enforcing a proposed prohibition on men using facilities designated for women, the Daily Wire reported.

The bill comes as Democrats prepare to welcome biological male Sarah McBride of Delaware, who is set to become the first transgender member of Congress.

“Sarah McBride doesn’t get a say in this,” Mace told reporters. “If you’re a biological man, you shouldn’t be in women’s restrooms.”

Mace added on X: “Never thought this would have to happen, but we are introducing a resolution banning biological men from entering protected spaces for women on Capitol grounds.”

“Protecting biological women starts here and it starts now,” Mace added.

Naturally, Democrats raged about the bill, with Rep. Becca Balint (D-VT) claiming: “The cruelty is the point.”

“This is a blatant attempt from far right-wing extremists to distract from the fact that they have no real solutions to what Americans are facing,” McBride (D-Del.) said in a statement, per Axios.

Added Rep. Alexandria Ocasio-Cortez (D-N.Y.): “This is not just bigotry, this is just plain bullying.”

Even some of Mace’s moderate Republican colleagues expressed openness to her resolution, Axios reported. “I’ll need more info,” said one. Another added anonymously: “I mean — a presidential election may have been decided on this issue.”

Other Republican members signaled that they were open to the bill and would take a further look at it.

“We’re going to talk about that,” said House Speaker Mike Johnson (R-LA). “We’re working on the issue.”
