I doubt just voting to not certify the electors of a state constitutes "aid or comfort" to insurrectionists. But there certainly were congress members who incited the insurrection along with Trump, or gave tours to people with full knowledge of their plans.
I bet when these things get into the courts, they end up being booted out of elected politics for life. That's going to make supporting Trump's stolen election lies less popular. But don't count on congress to do anything like that. Congress is not a court. And judges really HATE perjury, Clarence Thomas excepted.
The fact that Thomas was the only SC Justice to write a dissent supporting Trump's election lies is telling, when Trump nominated so many Justices.
