A Texas man described as a video editor for the conspiracy theory-promoting Infowars website has pleaded guilty to storming the US Capitol, where he captured footage of the scene where a police officer fatally shot a California woman who joined the mob’s attack.

Samuel Christopher Montoya faces a maximum sentence of six months of imprisonment after pleading guilty to a misdemeanour count of parading, demonstrating or picketing in a Capitol building.

US district judge John Bates is scheduled to sentence Montoya on February 14 2023.

Less than a week after the January 6 2021 attack, the FBI received a tip from a relative of Motoya who claimed to have proof he was inside the Capitol near the fatal shooting of Ashli Babbitt.

A police officer shot and killed Babbitt, a 35-year-old air force veteran from San Diego, as she climbed through a broken door leading into the House speaker’s lobby.

Identifying himself as “Sam with Infowars.com”, Montoya shot and narrated a 44-minute video showing him going from the Capitol grounds into the building, the FBI said.

Montoya, 37, described himself as a “reporter” or “journalist” on the video but was wearing a red “Make America Great Again” hat and made statements celebrating the mob’s attack.

“We take our house back. We take the people’s house back,” he said according to an FBI agent’s affidavit.

Montoya was credited as a video editor at “Infowarsstore.com” when he appeared on an Infowars show hosted by Owen Shroyer two days after the riot, the affidavit says.

The show broadcast the riot video taken by Motoya, who described to Shroyer what he saw and heard at the scene of Babbitt’s shooting.

The officer who shot Babbitt was cleared of wrongdoing by both federal prosecutors and Capitol police.

Montoya was arrested in Austin, Texas, in April 2021. Shroyer was also arrested on Capitol riot-related charges.

Shroyer has claimed he was acting as a journalist on January 6 and has asked a judge to throw out his riot charges. Prosecutors countered that the First Amendment does not protect Shroyer’s conduct at the Capitol that day.

Nearly a year ago, the House committee investigating the attack issued subpoenas for documents and evidence from Infowars founder Alex Jones.

Jones promoted former US president Donald Trump’s baseless claims of election fraud and urged his viewers to join him in Washington for the “Stop The Steal” rally on January 6.

Jones is not accused of entering the Capitol with the mob.

In October, a Connecticut jury ordered Jones and his company, Free Speech System, to pay nearly one billion US dollars (£870 million) in damages to compensate families of children and teachers killed in the 2012 massacre at Sandy Hook Elementary School.

The families said Jones broadcast lies about the school shooting which subjected them to harassment and threats.
