According to a State Department official, the latest batch of emails include 81 confidential messages, plus three that were upgraded to a "Secret" classification. ADVERTISEMENT In the previous round of releases, 22 emails were withheld after being classified as Top Secret. None of the emails released Saturday were upgraded to that level. None of the emails were marked classified when they were sent. In total, 45,830 pages of messages have now been publicly released.

The latest batch of email's come as the Obama administration is struggling to keep up with a court-ordered timeline to release all of the remaining emails this month.

The State Department has already angered a federal juge by missing a deadline to release all 55,000 pages of emails by the end of January.

“We're still working diligently on this,” State Department spokesman Mark Toner said Friday.
