That use of the 25th Amendment is a GREAT idea! I've actually thought that if Melania really wants to be a hero to her adoptive nation, she'd initiate divorce proceedings--- which by the same logic as "a sitting President can't be indicted because it would detract from his duties" would pretty much require that he take the 25th, as it were (since unlike with a criminal proceeding I don't think there's any legal justification for forcing someone to stay married to someone else just because the someone else is the President) (not that this bunch wouldn't revel in that abrogation of a woman's autonomy if they could pull it off).
