On Monday, the Huffington Post reported that federal authorities have arrested a New York man for his role in the violent invasion of the U.S. Capitol — and identified him because he wore his high school varsity jacket during the riot.

"Brian Gundersen, a former varsity football player for Byram Hills High School in North Castle Township, New York, is facing charges after the FBI received tips about a man seen storming the Capitol while wearing a letterman's jacket," reported Ryan Reilly. "The jacket included the name of his high school and his former jersey number."

"Federal authorities received a number of tips about Gundersen, and the North Castle Township police chief called the FBI's New York Operations Center to inform them about the man in the varsity jacket," said the report. "Numerous tipsters provided the FBI with photos of Gundersen wearing the same jacket, including selfies he'd posted with Fox News personalities."

According to the report, Gundersen's acquaintances confirmed he was "an avid supporter of former President Trump" and also a follower of white nationalist Nick Fuentes, who participated in the 2017 "Unite the Right" neo-Nazi riot in Charlottesville, Virginia. Fuentes was recently banned from YouTube for violating hate speech policies.

Gundersen initially denied he entered the Capitol in conversation with the FBI but ultimately admitted his role. "We all stormed the us capital [sic] and tried to take over the government," he wrote in one message. "We failed but f*ck it."
