State Department officials released roughly 800 of Hillary Clinton's private emails Friday evening, just hours before the South Carolina Democratic primaries begin.

The 1,500 pages of emails in the latest batch did not contain any "top secret" emails, an agency spokesman said. The State Department withheld 22 emails from a trove of emails made public earlier this year because they included "top secret" information.

Clinton faced a new wave of questions about her private emails this week after a federal judge ruled her top aides should be subject to depositions about their roles in setting up a personal server in Clinton's home. In addition, the judge threatened to subpoena Clinton and one of her top campaign staffers, Huma Abedin, over emails Clinton's legal team deleted in late 2014.

The State Department should have completed its review of Clinton's emails by the end of January under the original court order in the Freedom of Information Act case in question.

However, agency officials missed a court-ordered deadline on Jan. 29 after overlooking thousands of pages of emails that needed to be sent to outside agencies for review.

The State Department has been ordered to complete the publication of the remaining Clinton emails by Feb. 29. It is unclear whether the agency will make the new deadline.
