Justice Department attorneys said Wednesday that the FBI handed over two discs of Hillary Clinton's emails in late July: one that stored the roughly 15,000 deleted emails that agents are presently reviewing for release, and another previously undisclosed disc that stored an unidentified number of classified records.

The revelation came in a Freedom of Information Act lawsuit filed by Jason Leopold of Vice News, the same case that already forced the release of the 30,000 emails Clinton submitted in late 2014.

Government lawyers did not specify whether the classified emails provided by the FBI were included in the original 30,000 records or were among those Clinton and her lawyers deleted.

But the revelation seems to indicate that the classified emails are a new batch of records that hadn't been disclosed before, as they were provided alongside other records that the former secretary of state scrubbed from her server.

State Department attorneys on Tuesday admitted the agency had unearthed 30 Benghazi-related emails among the records recovered by the FBI.

Clinton's team pushed back by arguing that many of the 15,000 emails provided by the FBI were likely personal.
