The former Infowars correspondent will be sentenced Thursday. Biggs “served as an instigator and leader" during the Capitol attack, federal prosecutors said, requesting 33 years in federal prison.

A Proud Boys leader convicted of seditious conspiracy who the government says “served as an instigator and leader” during the Jan. 6 attack on the U.S. Capitol could face decades in federal prison at his sentencing Thursday.

The government wants Joe Biggs, an Army veteran who sustained a head injury in Iraq and then served as a correspondent for the conspiracy website Infowars, to serve 33 years in federal prison. That’s 15 years longer than the longest sentence in a Jan. 6 case to date: the 18-year sentence that went to Oath Keepers founder Stewart Rhodes, also convicted of seditious conspiracy, after prosecutors sought 25 years in federal prison.

Federal prosecutors say Biggs was a “vocal leader and influential proponent of the group’s shift toward political violence” and used his “outsized public profile” and his military experience as he “led a revolt against the government in an effort to stop the peaceful transfer of power.”
