Again I see a very easy solution to this.
Everyone who's been arrested for the Capital Riot can be bused to DC. We'll walk them all into the Capital Chambers, complete with all the weapons and accessories they had on that day.
We will then make an accouchement. "In 15 minutes, we are locking these people inside the Chambers, and turning off all the security cameras. An hour later, we will open them. We are giving them a blanket pardon on anything that happens within that one hour."
"So now, members of Congress. We have a decision to make. If they are just 'rowdy tourist' who didn't do anything, you can stay in here with them. However if you walk out that door before the doors lock in 15 minutes, that legally and bindingly counts as vote from you that what happened on December 6, 2021 was an armed insurrection on the orders of Donald Trump."
