(ABC 6 News) — Capitol police have confirmed an arrest after an alleged assault against Congresswoman Nancy Mace inside a congressional office building.

Police have released few details about the suspect identified as a 33-year-old from Illinois who now faces a charge of assaulting a government official.

This comes after Mace faced protests last month after proposing a bill that would ban transgender people from using restrooms on Capitol Hill corresponding to their gender identity.
