I am but a simple caveman, but it seems to me that if these people are proud of what they did before, during, and after the events of January 6th, and if they truly believed that those actions were both legal and proper, they’d have no reason not to offer depositions.
Great news! Make them sit and answer actual tough questions about their support and encouragement of the violent insurrection and do it with with the entire world watching and listening to their answers. Actually it’ll be their non-answers, but that’ll work as well.
What happens when they refuse to testify? We all know that’s coming. And, again, at the risk of being a broken record: Every single Democrat should make an ad asking: Do you know what happens when YOU don’t honor a subpoena?
