State Department documents reveal a nearly five-month total gap in the emails former Secretary of State Hillary Clinton decided hand over late last year, according to Judicial Watch.

Judge Andrew Napolitano explained on "The Real Story" that the first gap is a two to three-month period after Clinton took office in April 2009.

He said the more troublesome gap is the one between November and December 2012, since that immediately followed the Benghazi terror attack.

Judge Napolitano said Clinton has acknowledged that she sent or received 15,000 emails per year, so that two-month gap in 2012 means there are 2,500 to 3,500 emails that are unaccounted for.

"We're not talking about a miniscule number," Judge Napolitano said, reiterating those emails are property of the U.S. government and Clinton has a responsibility to turn them over to the State Department.
