Much is being made about Hillary not being under oath when she was interviewed by the FBI during the July 4th weekend. It doesn't matter. Under 18 United States Code Section 1001 it is a five-year felony to lie to an FBI agent (and other government officials) about a material fact relevant to an investigation. The federal criminal dockets are loaded with convictions of people who beat the underlying charge only to be convicted of an 18 USC 1001 offense.
If Hillary loses the election, keep an eye out for an Obama pardon, to choke off a retributive indictment by a Trump Department of Justice. There is a long road ahead for Mrs. William Jefferson Clinton before the statutes of limitations expire on her crimes.
