Judge Nap: FBI Must Have Found Something Substantial in Clinton-Related Emails

Conservative watchdog Judicial Watch has already filed multiple Freedom of Information Act requests related to Hillary Clinton's use of a private email server during her tenure as secretary of state.

Now, the group has filed a lawsuit to obtain the FBI's records of a meeting between Attorney General Loretta Lynch and former President Bill Clinton on June 27, which came just days before the bureau recommended no charges for the Democratic nominee.

Judicial Watch president and CEO Tom Fitton explained on "America's Election HQ" today that they are trying to get to the bottom of why "Mrs. Clinton got a get-out-of-jail-free card from [FBI Director James] Comey."

He explained that it appears the FBI and the Justice Department gave Clinton and other witnesses and potential targets preferential treatment during the investigation.

Fitton said there are lingering questions about what happened during that June meeting between Lynch and former President Clinton on board a parked private plane at Sky Harbor International Airport in Phoenix, Arizona.

He revealed that they've made multiple requests to obtain documents related to that meeting, but they have been "stonewalled" by the Justice Department and the FBI at every turn.

"Why is Loretta Lynch covering up details? Why is the FBI covering up details about that meeting?" Fitton said. "The law requires the documents be turned over. And you have federal agencies in violation of the law. And that's why we're in federal court trying to get the documents."
