Republicans have no interest in hearing the evidence. They don't want addition or new evidence to be presented. They don't want to be there. Chief Justice Roberts needs to assert the rules and demand that everyone stay in the room. Senator Blackburn needs to have repercussions for doing a Fox interview during the proceedings as well as others who stayed out of the room for periods over 5 minutes. In a real trial, the judge, jury, or anyone else involved, cannot just get up and leave. We all know the final outcome along party lines, but why can't they at least pretend to take it seriously? (And I know there were some Democratic senators out of the room too.)
