FCC Commissioner: We Were Told to Keep 'Obamaphone' Fraud Case Under Wraps

O'Reilly: The Democratic Party of Today Isn't the Same One Our Parents Embraced

On "Fox and Friends" this morning, Judge Andrew Napolitano reacted to the State Department striking an agreement with Judicial Watch to allow the conservative watchdog group to interview several of Hillary Clinton's key aides and staffers.

Judge Napolitano said that whatever Cheryl Mills, Huma Abedin, Patrick Kennedy and Bryan Pagliano say in this civil Freedom of Information Act lawsuit can be used against them in the criminal case regarding Clinton's private email server.

"The testimony in the civil case is compelled, the interviews in the criminal case [are] voluntary," he explained.

He said that if he were representing Mills, Abedin, Kennedy and Pagliano, however, he would recommend they plead the Fifth and decline to speak to Judicial Watch.

Judge Napolitano also shared insight on Clinton's reaction to this new development, and what it could mean for the case.

He said that the Democratic presidential front-runner's decision to brush off any questions about the investigation - which she called a "security review" in a recent interview - will anger the many FBI agents who are involved in the case.

"When she demeans the case, she demeans them," Judge Napolitano said. "It's crazy for her to do that."

He added that Clinton also made another misstep by repeatedly saying that she can't wait to speak to the FBI.

"Who in their right mind, being investigated by the FBI for espionage, can't wait to talk to them?" the judge wondered. "She's damned if she does and damned if she doesn't."
