In his speech, Trump called out the Dems finding votes at 4am before it happened.

One hypothesis: it was his last warning to them that he knew what they had planned. They went ahead anyways. So now his team has the possibility to catch many of them engaged in election interference, which is sedition and treason. I believe he changed it so sedition and treason can be tried in the U.S. military courts. So it could be his plan to start cleaning the swamp.
