Rep. Nancy Mace (R-S.C.) is doubling down on her efforts to keep biological men out of private spaces established for women after introducing a measure this week aimed at incoming transgender freshman Democratic Rep.-elect Sarah McBride.

Mace’s bill, the “Protecting Women’s Private Spaces Act,” would ban biological men from women’s spaces on all federal property, not just the U.S. Capitol Building.

It will “prohibit individuals from accessing or using single-sex facilities on federal property other than those corresponding to their biological sex,” according to a copy obtained exclusively by The Daily Wire.

The measure prohibits individuals from accessing facilities on federal property that do not align with their biological sex and includes clear definitions of what constitutes being male or female.

Mace created backlash this week when after introducing a bill banning trans-identifying men from women’s bathrooms or facilities on Capitol Hill. The resolution specifically states 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.”

Mace told Daily Wire host Michael Knowles that her legislation should not be controversial, arguing that independent voters and even Democrats are “with us” when it comes to “forcing this crazy gender ideology down the throats of our children and other Americans across the country.”

“I’m going to do everything I can to protect women and girls here on the Hill, but also across the nation,” she said, where she first unveiled her new bill. “This is a question that needs to be answered. Do women have rights or not? Are we going to allow these men to bully us into submission? And I say, no, no more. I’m done with this.”

“There’s no amount of bullying and threats on my life that they’ve made this week that’s going to stop me from this,” she added, promising to “fight like hell” for the protection of women and girls.

She also noted that she is a rape victim and is not at all comfortable with biological men in women’s spaces for any reason.

A leading conservative activist argued in a memo to Republicans on Tuesday that preventing men from accessing women’s bathrooms is both politically advantageous and the morally correct course of action.

“The American people sent Republicans to Washington with a mandate to protect women and children from transgender ideology,” American Principles Project President Terry Schilling wrote in the memo, obtained by The Daily Wire. “There’s no question about that. According to AdImpact data, Republican candidates spent $215 million in campaign ads on the issue, while Democrats struggled to respond. Republicans in the House and Senate should feel comfortable defending their positions not only because they are right and just, but because they are politically popular.”

Schilling argued that “it’s clear that the Democrats have failed to learn anything from their 2024 election defeat,” reminding lawmakers: “The American people voted for a return to normalcy — and they voted against the Democrats’ transgender extremism. But it’s not even December yet, and Democrats are leaning in on defending the ‘right’ of a male member of Congress to hang out in the women’s restroom.”
