A drive containing data on potentially every official in the Clinton administration was likely stolen from the National Archives and Records Administration in 2009, according to emails deleted by Hillary Clinton but recovered and released Thursday by the State Department.

The information was conveyed by Blake Roberts, a deputy White House counsel for President Obama, in a message that made it to Hillary Clinton’s private server in April 2009. “The National Archives alerted me that they cannot account for a 2 terabyte hard drive containing electronic records from the Clinton administration,” Blake wrote. “They believe it was stolen. NARA has an identical copy of the drive, which it is analyzing.”
