Yeah he could of just said he's a traitor and moved on.
For that matter, he could have just said, "Mike Pence is not under consideration as a running mate."
I think we'd all understand. No explanation necessary.
But I think the whole 1/6 melee was engineered to disrupt the proceedings, which were concluded in relative haste after the building was cleared.
Of interest is the timing of the doors being opened to admit the protestors (and the agents provocateur, CIs, UCs, and swarming DOJ types and operatives in the crowd), and how that relates to the progress of the proceedings for verifying the electoral votes.
Did that occur at a key time in the proceedings to disrupt the process at a critical time to prevent concerns from being voiced? Was it coordinated?
Sure, there were a lot of participants inside who were not LEOs or otherwise on the government payroll, but the overwhelming question is how many of them were let/led in the door by people who were ultimately under Pelosi's control, one way or another?
