Rehl, Biggs, Tarrio and Ethan Nordean were convicted of seditious conspiracy, while the fifth, Dominic Pezzola, was found innocent on the sedition charge.
All five were also convicted for obstruction of a congressional proceeding, impeding law enforcement and destruction of government property.
Biggs, 39, is a US Army veteran who had worked closely with Tarrio to organise the group to storm the seat of Congress.
Two months before the attack, he posted that it was time for “war”, referring to Trump’s election loss to Biden.
After Jan 6, he declared on social media that the attack was a “warning” for the government.
Ahead of sentencing Thursday, prosecutor Jason McCullough said what Biggs and his fellow rioters had done in shutting down the Congress that day was “no different than the act of a spectacular bombing of a building”.
“They aimed to intimidate and terrify elected officials,” he said, equating the Jan 6 attack to terrorism.
A tearful Biggs however expressed deep regret for what had happened.
“I’m so sorry,” he told the federal court in Washington.
“I know that I messed up that day, but I’m not a terrorist,” he said.
TRUMP BLAMED
Norman Pattis, the attorney for both Biggs and Rehl, told the court that they followed the guidance of Trump in undertaking the attack, and questioned why Trump himself had not been charged with sedition.
Earlier this month a Justice Department special prosecutor charged Trump with separate conspiracy crimes for his role in advancing the false claim that the election had been stolen from him.
“What they did is they listened to the president of the United States,” Pattis told the court.
