In February 2014, an unnamed Platte River Networks (PRN) employee created a Gmail email account and briefly transferred all of Clinton’s emails into it from a back-up of Clinton’s server made in the spring of 2013. He transferred the Clinton emails to a new version of this server, but most of the emails on this server will later be destroyed. He also will tell the FBI that he deleted all of the emails from his Gmail account after completing the transfer.
However, the FBI will later report that on June 21, 2016, FBI investigators discovered 940 Clinton emails that were still on the Gmail account somehow. It has not been explained if the PRN employee simply failed to delete them all or if deleted emails were recovered.
All of the 940 emails date from October 25, 2010 to December 31, 2010. 56 of them were later deemed to be classified at the “confidential” level. 302 of them were not in the over 30,000 emails that Clinton gave to the State Department in December 2014. It has not been specified how many of these were deemed work-related. But of the 302 emails, the FBI gave 18 of them to other departments to for classification review. The State Department decided one email was classified “secret” when it was sent, but then later was downgraded to “confidential.” Another email was “confidential” when it was sent and later downgraded to be unclassified.
