I don't believe the scope of the investigation is 'Everything about Trump ever,' though that seems to be what the DUmmies think it is. I suppose it does take a bunch of diehard anti-Trumpers down a rabbit hole and nothing will happen to Trump out of the whole thing, but I'm sure they will end up prosecuting somebody for something unrelated and unimportant to justify their own arson of vast piles of cash, like Scooter Libby's unfortunate situation.
