What part of the witnesses were already called and heard from seems to be beyond you? All of it apparently. The Senate are NOT the prosecutors, they are the jury. Jurors do not call witnesses. You do NOT get to change your mind and want other things AFTER the House concluded their sham. Now maybe stop grabbing your ankles for your Dim masters and actually learn something.
You know, dummy, your pretend arrogance and silly bloviation is kind of cute. Not having any idea whereof you speak, makes your spectacle a bit lousy, though.
The Senate conducts a trial - tries all cases of impeachment - meaning that the Senate along with the House Impeachment managers (the prosecution) form a court. Courts, as you may have heard, do hear witnesses. All the time, actually. The Senate heard witnesses in Johnson's trial, took depositions from called-upon witnesses, then reported to the whole Senate, in Clinton's case.
That is to say, you are wrong on all counts, and an insult to everyone's intelligence. Everyone's but yours.
As to that demented blab, "The Senate are NOT the prosecutors, they are the jury." Silly. Senators vote on the rules of the trial, quite unlike a jury. Senators render judgment, quite like a jury. Senators vote on subpoenas, on witnesses to call, on motions to adjourn, and a host of other issues, completely unlike a jury, as the Senate impeachment trial rules may provide.
You know what, lantern, switch on the light and search for a clue. The next you find will be your first. And no, your preferred "sources" in the rightarded blabbosphere won't help you any.
Finally, this is not a place to share your fantasies about anal penetration. Why don't you take your public self-pleasuring elsewhere?
