Neither Trump nor CM has ever uttered the word "Biden" in regards to 1/20.
You must learn to listen to what people DON'T say.
the fact is, we won't know for sure until 1/20/21.
The last check and balance is the Executive Branch, the other 2 have failed.
If all 3 branches fail, and we'll know 1/20, it goes to the fourth branch: the PEOPLE.
