I believe this is what the Clinton's have done. The private server was used for one purpose...evade investigation. My understanding is that some of this info had to have been removed from a secured network manually (such as thumb drive) then placed on an unsecured network.
Destruction of evidence, perjury, obstruction, mishandling sensitive info, influence peddling (pay to play), conspiracy...These are just a few that come to mind.
I believe the FBI has her in their sights and are finalizing the investigation with interviews of the players involved to attempt to see if they will begin obstructing an investigation/perjury under oath and or contradict one another and or sing like a canary.
I believe it IS what's occurring.
I also believe the DEPTH of this investigation will catch even the Clinton's off guard.
If they're NOT banished from the American political scene after this then we really have NO America anymore.
