 -- The State Department today released the largest batch of emails from Hillary Clinton's private server to date -- 7,800 pages.

Some 66 percent of the 52,000 pages of email she turned over to the government are now available for review and the State Department is on pace to have all of the documents released by January 2016, as ordered by a federal court.

The documents released today are mostly from 2012 and 2013, but include others that span her tenure as Secretary of State. The State Department has not been able to release the email in chronological order because much of it had to be set aside to be reviewed by other government agencies. Officials say many of those pages of email that have been held up were in today's release.

One email from November 2010, titled "Follw up," was just recently cleared by the Director of National Intelligence and deemed unclassified. The DNI had previously made public its decision to flag that email for further review. Although the content of the email was unknown until today -- it was a discussion between a New York Times reporter and a spokesperson at the State Department -- it and others still under scrutiny by government agencies have been seized upon by those critical of Clinton's use of a private email server.

Ultimately this email was not deemed classified, but many other have been. A State Department official tells ABC News that in this release alone 328 documents were upgraded to a classified level, meaning that they were redacted and are unavailable for public review. So far 999 have been graded as classified.

Scrutiny of Clinton and her her email problem by the Republican presidential candidates and the press has subsided in the weeks following her marathon testimony in front of the House committee investigating the 2012 Benghazi terror attacks. Republicans revealed emails in that hearing they claim show she was offering a different narrative to the public than she was in private. Clinton denied those claims.

The FBI still has an open investigation into the handling and security of Clinton's private email server and while it says it is not targeting Clinton directly, the outcome of that investigation may affect her run for the White House.
