Republicans are violating their oaths they just took. An impartial juror would want as much evidence as possible.
Soooo.....you didn't watch the proceedings in the House? Dolt.
Sooooooooo.... you didn't either else you would know that the Republicans were there & could ask questions. Republicans wanted witnesses that had nothing to add or to try to push the investigation to others. Like the whistleblower, only to find out his identity. Biden & Biden's son, who had nothing to do with Trump's bribe attempt.
The House was an investigation, not a trial. The Senate is holding a trial.
