Enrique Tarrio, the now-former leader of the neo-fascist Proud Boys gang convicted on treason-related charges after fuelling a mob on January 6, is set to be released from federal prison following Donald Trump ’s expected clemency order.

On his first day back in office, the president pardoned or commuted the sentences of those convicted over their roles in the January 6, 2021, riot.

Donald Trump supporters who attacked the U.S. Capitol four years ago will begin to leave prison on Tuesday, after the newly installed president issued a sweeping pardon that signaled he intends to make aggressive use of his executive power.

Until President Trump’s pardon, Enrique Tarrio was serving a 22-year prison term, the longest sentence handed down to any of the nearly 1,600 people charged in connection with Jan. 6.
