Was he the so-called surprise witness they called this hearing for?
I think the “surprise” new witness is actually the release for viewing of the recorded interviews made by the repubbies AFTER Jan 6 as part of a documentary telling the republican side of the story.
The demo’s are hoping to find a contradiction or some phrase in those interviews that will let them call Trump an “Insurrectionist” and thereby exclude him from running for future offices - as if he were a Confederate general who lost the Civil War.
