WASHINGTON (AP) — Two former leaders of the far-right Proud Boys extremist group were sentenced to more than a decade each in prison Thursday for spearheading an attack on the U.S. Capitol to try to prevent the peaceful transfer of power from Donald Trump to Joe Biden after the 2020 presidential election.

They were the first Proud Boys to be sentenced by U.S. District Judge Timothy Kelly, who will separately preside over similar hearings of three others who were convicted by a jury in May after a four-month trial in Washington that laid bare far-right extremists’ embrace of lies by Trump, a Republican, that the 2020 election was stolen from him.

Biggs and other Proud Boys joined the mob that broke through police lines and forced lawmakers to flee, disrupting the joint session of Congress for certifying the electoral victory by Biden, a Democrat.

“That day broke our tradition of peacefully transferring power, which is among the most precious things that we had as Americans,” the judge said, emphasizing that he was using the past tense in light of how Jan. 6 affected the process.

During the trial, jurors saw a trove of messages that Proud Boys leaders privately exchanged in the weeks leading up to the Capitol riot, including Biggs encouraging Tarrio to “get radical and get real men” after Trump announced plans for a rally on Jan. 6.

Rehl also led at least three other men into the Capitol and into a senator’s office, where he smoked and posed for pictures while flashing the Proud Boys’ hand gesture, prosecutors said in court documents.
