One email, sent to Clinton two days after the Benghazi attack, is drawing particular attention among the 7,000 pages. In the message, a State Department official in Tripoli advised against blaming the attack on anger in the Middle East over an anti-Islam video.

“It is becoming increasingly clear that the series of events in Benghazi was much more terrorist attack than a protest which escalated into violence," the email stated, adding that "relatively few" Libyans had seen the YouTube video.

At the House Benghazi Committee hearing last month, Republican lawmakers pointed to another Clinton email in which she told her daughter that the attack was carried out by an "al Qaeda-like group."

Napolitano said on "America's Newsroom" that it's unclear if or when Clinton read the Sept. 14, 2012 email.

But he noted that it was sent before a ceremony in which Clinton is said to have blamed the video in the presence of the victims' families.

Napolitano said this new development is "dangerous" for Clinton politically because independent voters could start questioning her trustworthiness. 

"Independent voters will likely deduce from this: how can we believe you?" he said.

He said it could also be dangerous legally for the former First Lady as the FBI investigates her use of a private email server as secretary of state. 

"The more evidence they see of deception, the more they ratchet up their inquiry into: 'has she ever lied anywhere else?' [and] 'did she lie under oath when she testified two weeks ago?'" he explained.

Bill Hemmer asked the judge whether there is legal "wiggle room" for Clinton in terms of how she explained these apparent contradictions at the hearing last month. 

"Yes, there's wiggle room legally. But she is the mistress of deception. She used words so carefully chosen to create the impression that she was not lying when she said this was done as the result of a video," he said.

Watch his full analysis above, and hear more from Judge Nap, tonight at 9p/12a ET on "The Kelly File."
