So, in its case seeking access to grand jury material for a possible (re)impeachment of @realDonaldTrump, which was scheduled for argument before the Supreme Court on December 2, ...
... the House Judiciary Committee moved to postpone the argument on the ground that @JoeBiden is going to be president on January 20, and, in essence, it would be a waste of time to argue the case, since Trump won't be there to impeach any more.
The Justice Department, which brought the case to SCOTUS (it lost below), basically responded by saying ...
: Your Honors, do whatever you want.

The court granted the motion this morning and took the case off its docket.

Bottom line: It seems as though neither the United States Department of Justice nor the Supreme Court of the United States believes @realDonaldTrump will be president after noon on January 20, 2021.
