President elect means he's going to be president. Why do you need to be reminded of this simple, most logical thing?
Did the people vote Trump into office or did Trump vote himself into office?

Since you still seem to be confused. The incumbent can still be charged with crimes until the 20th. Its just the justices involved don't have the guts to do it, and its moot anyway because he wont have to serve any punishments after the 20th.
You learned something today. You're welcome.
