According to Bloomberg News, the FBI has been able to recover at least some of the 31,830 emails deleted by Clinton. The exact number of recovered emails is still unknown. Clinton claimed she deleted those emails, which make up slightly more than half of all her emails from her time as secretary of state, because they were personal in nature.
Bloomberg News reports that, “Once the emails have been extracted, a group of agents has been separating personal correspondence and passing along work-related messages to agents leading the investigation, the person said.” This clearly indicates that not all of the deleted emails were personal in nature, as Clinton has claimed. Clinton’s spokesperson does not address the discrepancy, except to say that Clinton continues to cooperate with investigators. (Bloomberg News, 9/2/2015)
The same day, the New York Times also reports that deleted emails have been recovered. According to two unnamed government officials, “It was not clear whether the entire trove of roughly 60,000 emails had been found on the server, but one official said it had not been very hard for the FBI to recover the messages.” (The New York Times, 9/23/2015)
Chris Soghoian, the lead technologist for the American Civil Liberties Union (ACLU), comments, “Clinton’s private email server was secure. Clinton’s people didn’t know how to delete her old emails. These two things can’t both be true.” (Business Insider, 9/23/2015)
A September 2016 FBI report will reveal that the FBI was able to recover about 17,500 of Clinton’s deleted emails. However, a computer program was used to wipe parts of Clinton’s server, preventing the recovery of the rest. (Federal Bureau of Investigation, 9/2/2016)
