re: #241 Belafon

The day he resigns, some Democrat should announce that you cannot be pardoned for something you haven’t been convicted of.

Yet.
AFAICR (and said recollection MAY be faulty, of course: clarification will be appreciated) - the Ford/Nixon pardon did exactly that: and still hasn’t been legally challenged, and so (IIR) still stands as some sort of precedent.
Unfortunately.
