And then, there's this side of the whole matter: Trump may have said something to that effect or such, but out of honesty and concern, not authority or threat.
(Maybe a bit presumptuous on what happened, but point made.)
And one thought sums it up:
I'll say this here: Whatever was said, if anything, might have been nothing more than a heartfelt expression of hope about a friend made by a new President who had, until less than a month before, never been subject to the intricate legal, ethical, and political nuances of nuances of such a public office. Would it make sense to take down President Trump for being too NICE about someone?
We have a system for examining and adjudicating such matters. We shall see what happens.
