Washington, June 7 (RHC)-- The U.S. State Department has said it could take up to 75 years to finish reviewing thousands of pages of e-mail records belonging to former Secretary of State Hillary Clinton and her top aides.

State Department lawyers argue that according to court filings submitted last week compiling the 450,000 requested pages of records for former Clinton aides Cheryl Mills, Jacob Sullivan and Patrick Kennedy would take three quarters of a century.

"Given the Department's current [Freedom of Information Act] (FOIA) workload and the complexity of these documents, it can process about 500 pages a month, meaning it would take approximately 16-and-2/3 years to complete the review of the Mills documents, 33-and-1/3 years to finish the review of the Sullivan documents, and 25 years to wrap up the review of the Kennedy documents -- or 75 years in total."

During her tenure as the top US diplomat between 2009 and 2013, Clinton sent and received more than 2,000 classified e-mails using a private e-mail server at her home in New York.

The U.S. State Department's inspector general said in late May that Clinton's personal server violated the department's record-keeping rules and that it would have been rejected had she asked department officials.
