The State Department has released more than 500 more documents from former Secretary of State Hillary Clinton's email account.
The department says portions of 64 of the documents were upgraded to the "confidential" level, although none of the information was marked "classified" at the time the emails were sent. None of the 562 documents released Friday was upgraded to "secret" or "top secret."
The 1,116 pages made public Friday bring the total page count of released Clinton emails to 46,946.
The State Department plans to finish making her emails public on Feb. 29, a day before the critical Super Tuesday primaries.
