Attorney General Jeff Sessions led chants to "Lock her up!" at Donald Trump's campaign rallies during the 2016 presidential campaign.

So why isn't failed presidential candidate Hillary Clinton in prison for the illegal mishandling United States secrets?

A new FBI report — 42 pages of highly redacted material — shows then-President Barack Obama's Justice Department badly botched the case, including the mishandling of evidence.

The report is bad enough, some vocal critics have speculated the investigation was intentionally rigged.

"One redacted exchange reveals a back and forth subpoena response to the FBI from one of Mrs. Clinton's private attorneys, Katherine Turner, a partner at Washington DC powerhouse firm Williams & Connolly. In the document, Turner agreed to turn over one of Mrs. Clinton's non-secure Apple iPads and two of her BlackBerrys to the FBI," Fox News reported.

"But neither smartphone received from the law firm contain SIM cards or Secure Digital (SD) cards, and a total of 13 mobile devices identified by the FBI as potentially using clintonemail.com email addresses were never located by Williams & Connelly," they continued.

In other words, it seems evidence was missing or never surrendered… but the FBI still closed the case abruptly in October, nearly four months before Trump took office..

But there's still hope, according to Tom Fitton, president of the watchdog group Judicial Watch.
