After her staff sorted through the emails from her time as secretary of State, Hillary Clinton gave the State Department 30,490 emails deemed work-related and deleted 31,830 personal emails. So why did she turn over a blank server to the federal government this week? According to Bloomberg Politics, the FBI is exploring the possibility that Clinton’s team doesn’t actually know how to thoroughly scrub a server, or that she kept a backup copy of the messages (which may include classified information). Barbara Wells, an attorney for Platte River Networks, the company that managed Clinton’s private email, said the server now in the FBI’s possession “is blank and does not contain any useful data,” but she suggested that the data was migrated to another server. She reportedly ended the interview when Bloomberg pressed for information about this possible other server. A Justice Department spokesman would not comment on whether the feds are looking for another device, but presumably the hunt for Clinton’s yoga schedules continues.
