She knew she would become the Speaker in January, and so any bill in December was destined to die with the end of the 115th Congress.
This whole thing has been about the reemergence of Nancy Pelosi as a power broker. She wanted to start with a clean slate. We now know that she's willing to take the country to the brink of collapse to exert her power over everyone else.
If I were Schumer, I'd be very afraid. He's the one in the weakest position, not Trump. Pelosi is calling the shots regarding what gets into spending bills, and McConnell is calling the shots in the Senate regarding what bills get to the floor for a vote. Schumer is the one who has no power anymore.
