Intelligence experts have raised the number of Hillary Clinton's emails they think contain classified information to 305, State Department officials admitted in court filings Monday.

Those emails have been handed off to other agencies for further review as the intelligence community and the State Department together struggle to meet court-ordered deadlines for the production of Clinton's records.

Representatives from five different intelligence agencies had screened 23 percent of Clinton's emails as of Friday, according to the court documents obtained by the Washington Examiner.

Of that sample, the intelligence reviewers flagged 5.1 percent, or 305 documents, of the emails as containing potentially classified information.

The details emerged in a Freedom of Information Act lawsuit filed by Jason Leopold, a reporter for Vice News.

Leopold's case has forced the State Department to publish Clinton's emails on a rolling basis at the end of each month.

Officials fell short of the court-ordered benchmark in July, and plan to do so again in August, catching up only in December. The State Department has cited the extra burden of having intelligence experts screen the emails, a process that began in mid-July, as their reason for falling behind.
