Enrique Tarrio, the former leader of the Proud Boys, will spend the next 22 years in prison.
Tarrio was sentenced to 22 years in jail on Tuesday for his role in a failed conspiracy to retain Trump in office if the Republican lost the 2020 election.
Tarrio pleaded for forgiveness before the judge sentenced him to prison, but once the sentence was handed down, he raised his hand and formed a "V" with his fingers as he was brought from the courthouse.
It was the worst sentence that had yet been imposed in response to the attack on the US Capitol. According to District Judge Timothy Kelly, who was nominated to the bench by Trump, Tarrio was driven by "revolutionary zeal" to spearhead the plot that led in "200 men, amped up for battle, encircling the Capitol."
The judge ruled that a severe sentence was required to deter future political violence because Tarrio had not previously publicly shown regret for his conduct.
