Not turning over the power of the presidency triggers a constitutional crisis that goes all the way up to the supreme court

THIS is why they're desperate to impeach. Trump has the military and will simply glue himself to the seat of president and there's nothing they can do until the court hears "evidence" that Biden won "legitimately"

THAT is when Trump will get the floor to actually show the entire population what they haven't seen. ALL of it

this might also be why the timeline people are putting forward extends beyond the 20th
