I am not convinced the DNC computer was ever hacked by anyone. Only Hilarys staff claimed it was so. They refused to allow the FBI to investigate the claim and turned it over to another, a Hilary supporter company who only found thin evidence. There is strong evidence this is just another Democratic hoax.
What if this just another DNC/Hilary fabrication???
If the DNC server had actually been hacked then of course they would have gladly turned it over to the FBI for conformation of that.
Of course this is a fabrication... someone inside leaked these files and they know it. There's no other logical explanation for all these facts.
