Judge Andrew Napolitano appeared on "The Kelly File" tonight to weigh in on the latest developments in the Hillary Clinton email scandal.

A federal judge has demanded that Clinton and two of her most trusted aides go on the record "under penalty of perjury" regarding the private email server Clinton used during her time as Secretary of State.

Judge Napolitano noted that when the government suspected that Gen. Petraeus kept secure documents in his home, they raided it.

In Clinton's case, Judge Napolitano pointed out, the government doesn't suspect she has secure documents. It's a known fact.

Not only that, but she gave a thumb drive with that secure information to her lawyer, Judge Napolitano added.

"Mrs. Clinton should be treated like anybody else who is obviously violating the law by failing to secure classified documents and keeping them in insecure venues not approved by the government," Judge Napolitano stated.

He said that the federal judge's use of the phrase "under penalty of perjury" is extremely significant, because it reminds Clinton that for the first time, she will be under oath.
