An active-duty Marine Corps officer seen on camera scuffling with a police officer and helping other members of the pro-Trump mob force their way into the Capitol on Jan. 6 has been charged in the riot, federal prosecutors said Thursday.

Maj. Christopher Warnagiris, 40, of Woodbridge, Virginia, is the first active-duty service member to be charged in the insurrection, the Department of Justice said. Warnagiris, who has been stationed at Marine Corps Base Quantico since last summer, was arrested Thursday in Virginia, prosecutors said.

He faces charges including assaulting, resisting or impeding certain officers, obstruction of law enforcement during civil disorder and obstruction of justice.

Warnagiris was ordered released after a brief appearance before a federal judge in Virginia. It was not immediately clear Thursday if he had an attorney to comment on his behalf.

Warnagiris, who was wearing a dark jacket, military green backpack and black and tan gloves, pushed past police officers standing guard outside Capitol doors and forced his way into the building, according to court documents. He then appeared to use his body to keep the door partially open and helped pull others inside, authorities said.

A U.S. Capitol Police officer, who moved between Warnagiris and the crowd outside, tried to pull the door shut while Warnagiris fought to keep it open, court documents say. The officer told the FBI that he had tried to push Warnagiris out of the way and the man shoved him back, authorities said.
