At least 2,800 emails from the records recovered off Hillary Clinton's server by the FBI were related to her State Department work, government attorneys revealed Friday.

However, most of the files will not be made public until after the election, according to a schedule laid out by the State Department at a court hearing Friday.

Of the 15,000 emails collected by the FBI, 9,400 were deemed personal in nature and will be withheld by the government. Up to 50 percent of the remaining 5,600 emails could be duplicates of documents already made public by the agency, leaving at least 2,800 official records that have never been disclosed.

The revelations came in a Freedom of Information Act lawsuit filed by Judicial Watch. The Wall Street Journal first reported details of the new production schedule.

Separately, court documents filed in the same case on Thursday evening show members of the House Oversight Committee were provided sealed copies of records submitted to a federal judge by Bryan Pagliano, the Clinton IT aide who received an immunity deal from the Justice Department.

Pagliano's records were provided to the Oversight Committee "in camera" only, meaning members had to view the documents on terms dictated by the court and were never actually permitted to possess the documents.
