Rep. Nancy Mace, R-R-S.C., said she was physically attacked on Capitol grounds in Washington, D.C., on Tuesday evening and that the suspect has since been arrested.

The U.S. Capitol Police said the office of a congressman, later identified as Mace, reported an incident at the Rayburn House Office Building shortly before 6 p.m.

Officers from the House Division of Representatives and agents from the Police Department’s Threat Assessment Unit located the suspect, who was identified as 33-year-old James McIntyre of Illinois.

Police questioned McIntyre and ultimately arrested him for assault on a government official.

“I was physically attacked on Capitol grounds this evening because of my fight to protect women. The Capitol Police arrested him,” Mace said in a post on X. “All the violence and threats continue to prove our point. Women deserve to be safe. Your threats will not stop my fight for women!”

Mace has been vocal in her opposition to transgender people using restrooms that are not assigned to their biological gender.

She led the charge against allowing Rep.-elect Sarah McBride, a Democrat from Delaware, to use the women’s restrooms on Capitol Hill. McBride is a biological man who identifies and presents himself as a woman.

Mace said last month she had received death threats, adding that she was being “unfairly targeted.”

Mace also drafted resolution H.R. 1579, which would prohibit members, officers and employees of the House of Representatives from using facilities other than those consistent with their biological sex.
