There are a couple stories in WAPO that say that Trump broke quite explicit federal and Georgia laws with that phone call. Trump can't be removed from office by a court, only by impeachment and conviction, but that doesn't mean that he can't be convicted of a crime committed while in office, after he's out. And since the criminal act(s) comes only two weeks before he's gone, the statute of limitations won't apply. I really think Biden needs to appoint a special counsel to look into this. Isn't Hillary still a lawyer?
