The heavily-tattooed Trump supporter has been identified as Jake Angeli - dubbed the QAnon Shaman. Angeli was at the front of a group of agitators who broke into the Capitol and were facing off with DC police. He made his way into the Senate chamber where he was seen shouting and posing for photos on the dais. Angeli has become a fixture at recent right-wing rallies decked out in his signature attire.
