An Iowa man, accused of chasing after a Capitol police officer during the deadly pro-Trump riots last week, has been charged with federal crimes, according to court documents.

Doug Jensen of Des Moines appears to be the man seen in videos posted to social media leading a pack of Trump supporters chasing the cop up a flight of stairs.

In one video, posted to Twitter by Huffington Post reporter Igor Bobic, Jensen can be seen wearing a black QAnon shirt and black cap as he ran after the cops through the Capitol halls, and eventually running into other police officers.

The 41-year-old Jensen has been charged with six federal crimes including civil disorder, assaulting, resisting or impeding certain officers, entering and remaining in a restricted building, disorderly and disruptive conduct, violent entry and disorderly conduct, as well as parading, demonstrating or picketing in a Capitol building.

On Thursday, the FBI released dozens of photos of President Trump supporters who invaded the US Capitol during a protest on Wednesday, which killed five people, including a Capitol police officer and an Air Force veteran.

Michael Sherwin, the U.S. attorney for the District of Columbia, said at a press conference Tuesday investigators have identified at least 170 people they believe have played a role in the insurrection. More than 70 people have been charged and that number is expected to be higher, Sherwin said.
