My guess is that a deal was struck between the 10 or so key senators who could ensure acquittal: They would vote to acquit UNLESS the Trump team claimed vote fraud and went into that evidence.
I agree. I think Mitch and the rest of his ilk at the top of the party are in this fraud up to their ears. I believe Pres. Trump accomplished many positive things during his term, but none more important than exposing the level of corruption and bad actors that are killing America.
China is now in control of our govt with the help of the Dems and the Deep State.
This was the time to show the evidence as a lot of dem voters would be watching. Maybe knew there was not enough votes to convict. They just want this over and he can announce his run in 2024.
