Hillary Clinton’s emails from her private server will be released in January 2016, the State Department has told a federal court.

Since launching her presidential bid, Hillary Clinton has been on the defensive about her use of the server to conduct official business while she was secretary of state.

The timing for the release could prove tricky for her campaign.

The State Department says it will publish some of the 55,000 pages of emails online.

It proposed the date in court documents filed on May 18. The documents were in response to a Freedom of Information Act (FOIA) request made by Vice News.

The proposed date falls just a few weeks before the Iowa caucuses and other early state primary elections.

John Hackett, the state department official in charge of handling FOIA requests, said the 55,00 pages of emails were delivered in paper form and would require time to review before their release.

“Given the breadth and importance of the many foreign policy issues on which the secretary of state and the department work, the review of these materials will likely require consultation with a broad range of subject matter experts within the department and other agencies, as well as potentially with foreign governments,” he said.

Hillary Clinton, who voluntarily turned over emails from the server after discarding the ones she deemed personal, has said she wants the department to release the emails as soon as possible.
