I would bet that Pelosi was angling for a lighter sentence by obstructing the Senate and attempting to obstruct her own future treason tribunal.
Doesn’t seem to have gone to plan. Likely just added more charges to her future indictments.
I think this is what most if not all of the most rabid Trump critics really are doing. Asking for a deal by “damaging Trump or his agenda”. Only none of it seems to work and Q keeps saying no deals.
