Biggs appeared to be wearing a walkie-talkie during the Capitol raid, but he told FBI agents he did not know about the destructive riot and did not know who organized it, the affidavit said.
On the eve of the riot, Biggs told his followers on the social media app Parler to dress in black to look like the far-left antifa movement, according to the affidavit.
Biggs had organized a rally in 2019 in Portland, Oregon, attended by more than 1,000 far-right protesters and anti-fascist counter-protesters.
The Proud Boys are a neo-fascist group known for their involvement in violent clashes at political rallies. During the September presidential debate, Trump called on them to “step back and stay away”
The court’s online file did not say whether Biggs had a lawyer who could comment.
Jesus Rivera, 37, was also arrested Wednesday in Pensacola. He is accused of deliberately entering a confined building with the intent of obstructing government business, disorderly conduct, and demonstrations in Capitol buildings.
Rivera uploaded a Facebook video appearing in the crypt of the US Capitol, authorities said. The five-minute video ends with Rivera, who begins to climb through the Capitol window, according to an arrest warrant.
Rivera’s lawyer is also not mentioned in the court’s online file.
The cases are being handled by federal prosecutors in the District of Columbia. More than half a dozen other Florida residents have been charged in connection with the Capitol attack.
