Whelp, here's why we don't do that. A Senate impeachment trial is not a CRIMINAL trial. It isn't proving a crime occurred nor can it administer judicial penalty for it.
Nancy Pelosi already confessed the Impeachment is a sham, an abuse of power being carried out to protect the Democratic Partyfrpm a perceived future political threat.
The FBI has already proved that the events of 6 Jan was the result of pre-planning that did not include the knowledge or participation of the President.
The President's speech Transcripts prove he did not call for violence - just the opposite.
The reason the Democrats have had to put a Trump-hating Democrat as witness, juror, and Judge is because al the evidence - and Pelosi's confession - dstroys their case,
whelp.
