Joshua Lollar, 39, was identified by FBI agents after appearing in a Facebook live video while he clashed with and overtook police officers as he made his way inside the Capitol building, according to court documents released Friday.
Lollar became a person of interest through a tip from a co-worker to the FBI National Threat Operations Center, court records stated.
"It appears that Lollar was at the front lines of a physical confrontation with MPD officers," federal court documents read.

The Spring man told FBI agents he traveled to Washington and attended the speech given by President Donald Trump at the Ellipse before returning to his car, the agent said. Lollar later got out and followed a crowd headed toward the Capitol. Body camera footage from D.C. Metro police officers showed a man believed to be Lollar wearing a gas mask, gloves and a tan-colored body armor vest, court documents stated.
"Yeah, I'm good," Lollar wrote on Facebook on the evening of Jan. 6, according to the FBI agent. "Just got gassed and fought with cops that I never thought would happen. I don't know what we can do, but I'm trying my best to get it done peaceful. We can't loose (sic) our America."
After posting, someone believed to be a close family member sent Lollar a message telling him to 'clean off' his page out of fears of prosecution.
"Please get off Facebook or delete you in the capital (sic)," the person wrote, according to court records.
Reached by phone on Friday afternoon, Lollar's father, Grover, told ABC13, "He's not a domestic terrorist or insurrectionist. He went for a rally. They just rushed down there, and he got swept along."
Grover also said his son is a disabled Army veteran.
"He's a good man," Grover added. "He's not a criminal."
In a Friday evening pre-trial hearing, the court discussed Lollar's history of psychological issues and if he had to remain in custody until trial. Prosecutors said Lollar's admittance of having guns was an issue that could complicate his release, and until someone else came to court to say his guns were in their possession, they would prefer Lollar remain detained.
Lollar is expected back in court on Tuesday, Jan. 19 at 10 a.m.
According to the FBI, he is charged with knowingly entering or remaining in any restricted building or grounds without lawful authority and impeding or disrupting official functions. If convicted, he could face a year in prison and a $100,000 fine.
He's also charged with obstructing or impeding law enforcement officer during civil disorder and obstructing federally protected functions. If convicted, Lollar could face up to five years in jail with a $250,000 fine.
Lastly he's charged with violent entry and disorderly conduct on Capitol grounds, for which he could be jailed up to six months and pay a $5,000 fine.

Lollar was at least the second person in the Houston area to be identified as part of the mob that forced its way into the building while a joint session of Congress met to certify Joe Biden's electoral win.
A joint investigation continues into former Houston police officer Tam Pham, who resigned from the department after revelations he was in the building that day.
Pham's attorney told ABC13 this week that he has spoken at length to local FBI agents and "continues to cooperate."
While Lollar and Pham have been identified by separate sources, the FBI has refused to provide specifics about local citizens' possible involvement in the violence and breach, citing the ongoing investigation.
