It's obvious to me that the Committee is stuck trying to keep Pelosi & her henchmen out of it. They can't. The minute-by-minute logistics of the Capitol Police have to be explained as they relate to witness-statements.
As for Team Trump, they were all blocks-away. That means the entire cases will be about phone-records. Even deeper scrutiny of what Capitol Police were doing and who told them to do it.
Deep State thought they were being clever by planning on a wimp like McCarthy panicking and actually believing the left's scuttlebutt... thus he unwittingly called Trump. That's where we are now, but the story doesn't even last 2-hours in the news-cycle before fading below the surface again.
I believe Pelosi's phone-records will requested, if they haven't been already.
