A Trump appointee who has been arrested in connection with the Capitol riot fought police and used a riot shield to wedge the door to the building open, an affidavit said. 

Federico Klein, then an employee of the State Department, is believed to be the first Trump appointee facing charges in relation to the events of January 6.

The document was published late Thursday by The New York Times, which also reported Klein's arrest.

An FBI agent identified Klein, in a MAGA hat, among the mob that crammed into a tunnel leading to the Lower West Terrace entrance to the Capitol building from surveillance and police body camera footage from the day.

In the tunnel, Klein pushed to the front of the crowd and "physically and verbally engaged" with police, preventing them from doing their work, the affidavit says. 

Around half an hour later, he was caught on camera among a crowd trying to push through doors to the building, according to the document.

An officer shouted "back up" six times, a command that Klein ignored, the affidavit says.

Instead, it says, Klein wedged a riot shield between the doors, preventing police from shutting them out.

The document describes it as "either an MPD or an U.S. Capitol Police riot shield." It said the shield "apparently had been taken from an officer," but did not offer details.

Describing the video footage, the affidavit says Klein was seen "resisting officers, attempting to take items from officers, and assaulting officers with a riot shield."

Using the shield to shove at police, he got into a sustained battle in an attempt to fight his way into the building, the affidavit says.

He was eventually moved away with the use of chemical irritant spray, it says.

But he still attempted to get in, investigators say. Other footage appears to show Klein brawling with police and encouraging the crowd. "We need more people, we need more people," he yelled on more than one occasion, according to the footage described. 

Eventually, the mob was pushed out of the tunnel.

Outside, it looked like Klein lost his MAGA hat and found another one. 

But the investigators said they were able to identify him by a rip in his jacket that also appeared in footage when he was wearing the MAGA hat, marked with a green arrow in the pictures below. 

When an officer, named "Officer 4" in the affidavit, was dragged into the crowd, Klein refused to move out of the way to allow police to go in and rescue him, saying "no way," the affidavit says. 

"Let me get my friend," one of the officers is recorded as saying. 

When Officer 4 made it out of the crowd, Klein is then pictured appearing to help him make his way back to the tunnel, investigators said. 

Tipsters got in touch with the FBI after a "wanted" poster was circulated on January 20. From that, one tipster led officials to the Facebook page of "Freddie Klein," whose picture appeared to be man from the footage, while a witness led them to a LinkedIn profile for the same name. 

Klein is one of hundreds of people arrested in connection with the events of January 6 in an aggressive police investigation.

Klein resigned his position on January 19, according to the affidavit.
