FBI investigation was never about the email server. It has always been about Racketeering.

Gingrich makes a good point. This is about racketerring. The email server and the missing emails contain the evidence to prosecute both Bill and Hillary, Chelsea and many others of racketeering. May even get Obama in the crossfire.

The Clinton Foundation truly is a criminal organization. I suspect Comey didn't pursue charges on the emails as a way to get the Clinton crime family and leftist media to take their eye off the ball, while the FBI quietly persued RICO charges.

Maybe the Clinton's thought they had Comey bought and paid for but...being the FBI director that brought down the biggest political crime family in history and wrecking a corrupt national political party in the process, is worth so much more money than Hillary can cough up. Think of the book deals, legacy, etc.
