Federal prosecutors on Thursday for the first time described last week’s assault on the U.S. Capitol as a “violent insurrection that attempted to overthrow the United States Government” — and one they consider to still be underway…

Chansley, an Arizonan who also goes by Jacob Angeli and “Q Shaman,” has become a social media fixture in the aftermath of the mob violence at the Capitol, which left five dead and resulted in the impeachment of President Donald Trump for “incitement of insurrection.” A shirtless Chansley has been seen in numerous pictures carrying a six-foot spear, donning horns, a coyote tail headdress and face paint — including one on the Senate’s rostrum.

Prosecutors say Chansley has expressed his intention of returning to Washington for the inauguration of President-elect Joe Biden — and that his pending criminal case is unlikely to be a deterrent.

“Chansley told the FBI prior to his arrest that he’ll ‘still go, you better believe it,’” prosecutors said in the 18-page filing. “His status as a symbol of the insurrection, his actions inside the Capitol building, and his demonstrated disregard of orders while inside with the goal of disrupting official Congressional proceedings, demonstrate the danger his release would pose.”
