WASHINGTON (AP) -- The State Department has released more than 1,000 new pages of Hillary Clinton's emails.
Eighty-one messages were classified, mostly at the lowest level of sensitivity. None was declared top secret.
The department has now released more than 45,000 pages of emails from the private account Clinton used as secretary of state.
It plans to finish making her emails public on Feb. 29, a day before the critical Super Tuesday primaries.
Clinton has struggled to put the email controversy to rest as she seeks the Democratic presidential nomination.
Last month, 22 emails were withheld in full because they contained "top secret" material. The FBI also is examining the security of the homebrew server she maintained for email use while in office.
