The trial of Proud Boys leader Enrique Tarrio and four other members opened Thursday.
"Make no mistake…," read one text from Tarrio sent at 2:40 p.m. after rioters broke into the Capitol, according to prosecutors.
"I'm proud as fuck at what we accomplished yesterday," read one message from Biggs, according to prosecutors.
The DOJ also invoked comments made by Trump during a September 29, 2020, presidential debate, telling the Proud Boys to "stand back and stand by" when he was pushed to condemn white supremacists and militia groups.
"When it became clear that Donald Trump would be voted out of office," McCullough said Thursday, "these men did not stand back, they did not stand by, instead, they mobilized."
