Prosecutors have decidede not to pursue an assault charge against a man whom  South Carolina GOP Rep. Nancy Mace alleged assaulted her at the U.S. Capitol.

In December, Mace alleged that James McIntyre "physically accosted" her at an event marking the 25 years of the Foster Care Independence Act.

McIntyre pled not guilty to the assault charge, according to a court filing Tuesday with the D.C. Superior Court.

Prosecutors decided to drop the single charge, according to NBC News.

Despite the charge being dropped, Mace still said she was assaulted.

“When a man can physically assault a woman in the halls of Congress, with impunity, it sends an appalling message to every woman in America," she said Thursday. "If it can happen here, it can happen anywhere. I filed charges, and they were inexplicably ignored. But I will not be. I will not back down. I will not be intimidated. And I sure as hell won’t stay silent.”

McIntyre said he was "pleased but not surprised that these baseless charges have been dropped."
