That's something, but I also can't help think that, no matter what, this is "too little, too late". If it had been leaked in October, or even before the Electoral College vote in December, this could have had an impact.
Now? I don't know if there is anything that can be done, short of impeachment (which I don't see happening without absolute evidence).
They brought Bill Clinton to trial for less
Other than that we can only hope that he gets covertly assassinated by the intelligence agencies he's shown so much disdain for.
Yeah, but Clinton wasn't their own party. It was politically expedient to do that...whereas many Republicans ended up (reluctantly) backing Trump. It's egg on their face if it turns out he was a patsy for the FSB all along.
