A move by the FBI & DOJ.
Ohhh, POTUS is pushing them to reveal their determined distance from this issue.
It needs to remain un-acted on.
It discredits the investigation into HRC's emails because now we know where an entire collection of them are, and now we also now that THEY KNEW ABOUT THIS THE ENTIRE TIME.
It may open the door due to proven and intended incompetency - so SOMEONE ELSE NEEDS TO PICK UP THE INVESTIGATION?
And that's a great question, Why the hell was it on his laptop in the first place..
