I do not personally know who did what on January 6th. I do know that Dems have no actual interest in an objective, truthful, apolitical review of what happened. Why? Because the "committee" has specifically rejected the idea that what Nancy Pelosi did or did not do on that day is relevant to understanding the events. They rejected Republican members because they were going to call "inconvenient" witnesses.
I also know that the FBI HAS used a tactic with foreign terror cells where they insert an agent and then that agent actually helps plan and push attacks. They've done it. EVERYONE should be interested in the TRUTH about whether they did it on January 6th or not. If they didn't... fine. But those records should NOT be sealed and those potential witnesses should NOT be silent.
