Rep. Nancy Mace (R-SC) has been subjected to mounting threats against her safety over the past month after standing in opposition to biological males who claim to be transgender women using women-only bathrooms and locker rooms at the U.S. Capitol complex.

Those threats may have come to fruition on Tuesday as Mace claims that she was physically assaulted by a leftist transgender rights advocate who was subsequently arrested and charged by Capitol Police, according to Reuters.

Police charged James McIntyre, 33, of Illinois, with assaulting a government official, even as Mace's account of what occurred has been disputed by other leftist activists and the media.

Congresswoman assaulted by activist

In an X post on Tuesday night, Rep. Mace wrote, "I was physically accosted tonight on Capitol grounds over my fight to protect women. Capitol police have arrested him. All the violence and threats keep proving our point. Women deserve to be safe. Your threats will not stop my fight for women!"

Last month, Mace introduced legislation that would restrict access to single-sex restrooms at the Capitol complex to an individual's corresponding biological sex -- a move spurred by the election of Rep.-elect Sarah McBride (D-DE), a biological male who will become the first openly transgender woman in Congress once sworn-in in January.

Her strong stance on behalf of safety for biological women sparked outrage among Democrats, leftist activists, and their media allies, and have led to threats of violence and angry confrontations.

Mace provides updates on her situation

In a series of posts to her official X account on Wednesday, Rep. Mace first shared, "Just got off the phone with @Realdonaldtrump. Thank you, Mr. President, for checking in on me and for standing up for women. We cannot wait to see you back in the White House."

"Nobody will twist my arm (literally) or break me into bowing to leftwing extremists," she said in another post, after which she called out the "usual suspects in the media" who were "using the assault on me to prop up misogyny on the Left, giving a platform to activists chasing their 15 minutes of fame," and added, "You don't hate the corporate media enough."

Mace also took aim at her Democratic colleagues and posted, "The Left, the self-proclaimed 'party of women,' haven't said a damn thing about a woman being accosted at the Capitol."

She further suggested in one post, "Maybe when the Left said 'believe all women,' they really meant men who claim to be women," and wrote in another, "The Left only wants you to believe all women when it's politically expedient for them."

The congresswoman also posted multiple pictures of herself wearing a sling to support her apparently injured arm.

Man pleads not guilty; Mace's story disputed

CBS News reported that McIntyre pleaded not guilty to misdemeanor assault of a government official during a Wednesday court appearance, after which he was ordered released from custody by a magistrate judge.

Rep. Mace's account of being physically attacked has been disputed by some who've downplayed what McIntyre did after a foster youth event at the Capitol as little more than an "exaggerated, aggressive" handshake as he introduced himself to the congresswoman and advocated for transgender rights.

Per Reuters, Lisa Dickson, a fellow foster youth activist, said of the claim against McIntyre, "I want to express deep disappointment in the fact that Congresswoman Nancy Mace came to a national foster youth event, told participating youth that it was a safe space -- and literally had one of them arrested by Capital police for simply shaking her hand and asking about trans rights."
