Nancy Mace Introduces NDAA Amendment On Single-Sex Military Facilities

(Washington, D.C., September 9, 2025) – Congresswoman Nancy Mace (SC-01) has submitted an amendment to the National Defense Authorization Act (NDAA) to prohibit individuals from accessing or using single-sex spaces on military installations which do not correspond to the biological sex of the individual.

Building on President Trump’s executive order, Defending Women From Gender Ideology Extremism, and Restoring Biological Truth, which directs federal agencies to base single-sex facilities and policies on biological sex, Rep. Mace is committed to protecting women’s spaces. By applying the same principle to the military, her amendment ensures bathrooms, showers, barracks, and locker rooms on U.S. bases will remain grounded in biological reality.

“Our men and women in uniform deserve privacy, safety, and common sense on base,” said Congresswoman Mace. “This amendment enforces the mandate President Trump put in place to uphold immutable biological truth by ensuring single-sex spaces are protected from the opposing sex. Men do not belong in women’s facilities: not in the military, not on taxpayer-funded property, not anywhere.”

The measure reinforces Rep. Mace’s fight to restore accountability and common sense in the military, keeping our armed forces focused on mission readiness. It also advances Rep. Mace’s legislative efforts to protect women’s spaces, including the Protecting Women’s Private Spaces Act, which safeguards single-sex facilities on federal property, and the Restoring Biological Truth in Government Act, which requires federal agencies to recognize only male and female based on biological sex.

The amendment will now be taken up by the House Rules Committee for possible inclusion in the NDAA.
