A man was arrested Tuesday after Rep. Nancy Mace (R-S.C.) said she was accosted.

“I was physically accosted tonight on Capitol grounds over my fight to protect women. Capitol police have arrested him,” Mace said in a post on X.

U.S. Capitol Police confirmed the incident, noting they arrested a person accused of assaulting a lawmaker.

The police did not specifically name Mace in their statement but said a member of Congress’s office reported an incident just before 6 p.m. inside the Rayburn House Office Building.

“House Division officers, and agents with the Threat Assessment Section, tracked down the suspect,” police said in a statement.

The suspect was identified as 33-year-old James McIntyre of Illinois. He faces a charge of assaulting a government official.

Police noted that the Rayburn building was open to the public at the time of the incident, and McIntyre went through security screening before entering the Congressional building.

Mace, who has been at the center of controversy after introducing a bill that bans transgender women from using women’s restrooms on Capitol Hill, shared the news on X.

She’s received sharp criticism from LGBTQ advocates on the bill and noted her ongoing fight in her post. Mace has argued she introduced the legislation as a safety point for women.

“All the violence and threats keep proving our point. Women deserve to be safe,” she said. “Your threats will not stop my fight for women!”
