As much as we’d like to see the Logan Act enforced, it is essentially unprosecutable.
So the really question is how do we stop it? The only way I can think of on a Sunday morning in December is; to give the man enough rope to hang himself(no that’s not meant to be racist.) My issue with it is it might end up being a very,very long rope.
I do think those wheels are in motion, “giving someone rope and then reeling them in” seems to be a favorite Donald Trump solution.
