LOS ANGELES (CNS) — A UCLA student from Costa Mesa who allegedly identifies as a "fascist" and "invites white nationalists to speak on campus" is facing federal charges of participating in the insurrection at the U.S. Capitol, including breaking into the Senate chamber and sitting in the vice president's chair.

Christian Secor, 22, was taken into custody Tuesday after agents searched his home, FBI spokeswoman Laura Eimiller said. He is charged with assaulting, resisting or impeding officers, violent entry and remaining on restricted grounds, civil disorder and obstructing an official proceeding, according to a criminal complaint filed Tuesday in the District of Columbia.

Secor made his initial appearance Tuesday in federal court in Santa Ana, where a magistrate judge ordered him held without bail.

According to an affidavit filed in support of the charges, Secor can be seen on video footage pushing his way past officers attempting to block doors leading into the Capitol on Jan. 6, while wearing a red hat bearing the slogan "Make America Great Again."

He was also spotted on the floor of the Senate and sitting in the chair of the presiding officer, while carrying a flag with the words "America First," according to the document.

FBI agents received at least 11 tips identifying Secor as joining the insurrection, according to the affidavit.

Bill Kisliuk, UCLA's director of media relations, did not comment specifically about Secor.

"What I can tell you is that UCLA believes the Jan. 6 attack at the Capitol was an attack on our democracy," he said. "As an institution, UCLA is committed to mutual respect, making decisions based on evidence and using rational debate and not physical violence."

The affidavit states that a fellow student identified Secor as a UCLA undergrad and founder of America First Bruins, a conservative campus organization. Other people who allegedly knew him supplied photos of the defendant participating at a rally in Huntington Beach, and told agents that he has written social media posts that America should become a "whites-only" nation, according to the complaint.

"In one of the videos provided by the U.S. Capitol Police, Secor can be seen among a group of rioters attempting to push through a doorway that is blocked by no less than three police officers and breaking through a police line," according to the FBI.

Pushing through the double doors allowed dozens of rioters to flood into the building, the FBI said.

"The Capitol Police officers were shoved by the crowd, at times trapped between the doors and the crowd, and eventually pushed out of the way of the oncoming mob," according to the FBI.

Secor goes by the nickname "Scuffled Elliott Roger," which is "believed to be a reference to the 2014 Isla Vista mass murderer and (UC Santa Barbara) student who fatally stabbed his three roommates," according to the FBI.

Secor also allegedly has tweeted that fascism is "epic," according to the FBI affidavit, which also alleges he "valorizes the 2017 Charlottesville tiki torch march, which featured chants of 'Jews will not replace us!..." and "states that he supports 'nationalism everywhere,' and suggests Jews and the state of Israel control the politics of other governments and attempt to influence 'Westerners."'

The FBI also alleged that Secor "defines himself as a fascist" and "has posted threats online and openly posted calls for America to become a whites-only nation," and that he "is known to follow an extreme ideology and invite white nationalists to speak at engagements on campus."

One tipster told FBI agents that when Secor returned from Washington, he "moved back in with his mother in Costa Mesa got rid of his phone and car and bragged that he would not be caught for his involvement at the U.S. Capitol."

Last month, a Huntington Beach man was arrested on federal charges of participating in the Jan. 6 insurrection. Mark Steven Simon, 49, was charged with misdemeanor counts of entering restricted buildings or grounds, unlawful activities on Capitol grounds and disorderly conduct.

Also in January, a Beaumont man and Federal Aviation Administration employee who subscribed to the QAnon conspiracy theory was charged after allegedly confessing to taking part in the U.S. Capitol breach, according to court documents. Kevin Strong, 44, is charged with violent entry and disorderly conduct on Capitol grounds, entering or remaining in a restricted area and being disorderly or disruptive in a restricted area.
