A federal judge ordered the Department of State on Thursday to explain their delayed pace in producing emails former Secretary of State Hillary Clinton stored on a private server.
A hearing was held to check in on the State Department’s progress in processing and releasing 72,000 pages of non-government emails that Clinton failed to disclose during her tenure as Secretary of State and later tried to delete.
The State Department was ordered to turn over no less than 500 pages of emails per month to Judicial Watch in response to a 2016 Freedom of Information Act (FOIA) request. They have thus far processed 32,000 pages and released a small fraction of those. If they continue at this pace they will not fulfill the request until 2020 at the earliest, according to Judicial Watch.
