The State Department released more than 500 new documents from former Secretary of State Hillary Clinton’s private email account Friday,  including 64 that contained classified information.

However, the "confidential" information contained in those 64  was "not marked classified at the time they were sent," a State Department spokesperson told Fox News, echoing a position repeated by the 2016 Democratic presidential candidate’s campaign in recent months.

The 562 new documents posted online totaled 1,116 pages of emails. The latest public release brought the total number of pages released to 46,946, or about 85 percent of the 55,000 pages originally surrendered by Clinton.

Friday’s release brought the total number of public Clinton emails containing classified information to 1,731.

A judge earlier this month ruled that the State Department must release emails "before close of business" following a late January email release at 2:30 am.
