On November 2, 2016  Fox News reported:

FBI agents have interviewed and re-interviewed multiple people on the foundation case, which is looking into possible pay for play interaction between then-Secretary of State Hillary Clinton and the Clinton Foundation. The FBI's White Collar Crime Division is handling the investigation[.]

Hillary is facing two investigations, one in her use of a private email server in violation of the applicable statutes, and one in the pay-for-play scandal at the William J. Clinton Foundation, aka the William J. Corleone foundation. 

It appears that there is a "Deep Throat" at the FBI , or more than one, fed up with the interference by the Obama Justice Department with the investigations of the Foundation and the emails, and with FBI director Comey's July 5, 2016 decision not to recommend indictment on the basis that Hillary did not have criminal intent.  Sources at the FBI are finally informing the public.

The investigation into the Foundation will cause more problems for Hillary because it is easy to follow and understand: Hillary and Bill got lots of money by giving speeches and money to the Foundation in return for Hillary using her office as secretary of state doing favors for those paying.  The public will be more incensed at the amount of money the Clintons received for selling her office.  The emails are just as important because of the national security issues, but money for favors is the essence of corruption that upsets voters.

The money for favors is also consistent with Hillary and Bill selling the pardon to Marc Rich for one million five hundred thousand dollars.

Follow the money from those receiving favors to contributions to the Foundation and speech fees for Bill.
