WASHINGTON (CBSNewYork) -- The State Department has released another batch of Hillary Clinton's private emails.
The department said the process of releasing them is slow, because U.S. intelligence agencies have to make sure they don't contain any government secrets.
As CBS2's Weijia Jiang reported Friday, there is some controversy.
The State Department released 2,200 emails from the former secretary of state's personal account, after a federal judge slammed the agency this week, saying it hasn't been "anywhere near aggressive enough."
"There were monthly goals as you note and we fell short this month," State Department deputy spokesman Mark Toner said. "We need to obviously be fast. We need to make every effort to meet these deadlines, but we also need to be accurate and make sure other agencies' equities are taken into consideration."
In the newly released documents, more than 60 passages were blocked from being published to protect national security secrets. In all, Clinton, a leading candidate in the race for the White House in 2016, has turned over some 55,000 pages and has repeatedly said she never sent classified information.
State Department staffers also want to look at emails from some of Clinton's top aides, but an attorney told the judge handling the case the agency has had trouble obtaining them, Jiang reported.
"The vast majority of the emails that I have turned over and that are being turned over by others were already in the State Department system," Clinton said.
Questions about the emails have been following Clinton on the campaign trail, and affecting her poll numbers with voters when it comes to her trustworthiness.
Republicans on the House committee investigating the Benghazi attacks are very suspicious that some of Clinton's emails are missing from the public record.
She is expected to testify before that committee on Oct. 22.
