The State Department revealed on Friday that the FBI uncovered 2,800 more emails that former Secretary Hillary Clinton never turned over, The Washington Times reported.
The investigation agency also said it will begin releasing the emails in batches from next month.
The department argued that only a small chunk of the emails will be processed before the November elections due to scarce resources.
So far, the FBI turned over 15,171 emails it recovered that involved Clinton of which 60 percent have been classified as purely personal. Around 5,600 emails are work-related but there is a possibility of half of them being duplicates.
The department had been given deadlines to process three sets of 350 pages each by Oct. 7, 21 and Nov. 4. Processing the documents would involve reviewing them to decide what can be released. The deadlines for processing are not meant for public release, the Times reports.
Judicial Watch President Tom Fitton, whose organization has sued to get a look at Clinton’s messages said, “The State Department is being obstructionist.”
The State Department’s lawyers, though, complained they were facing difficulties in hiring staff to review the messages owing to hard work and long hours.
“This has been a very difficult and demanding job these days, and not a lot of fun,” Marcia Berman, a Justice Department lawyer handling the Clinton cases, was quoted as saying.
