The ongoing vetting of Hillary Clinton's emails for public release has turned up classified information in roughly 150 more messages, the State Department said Monday.
The disclosure came ahead of Monday night's planned release of more than 7,000 additional pages of the Democratic presidential front-runner's messages from her tenure as secretary of State, which will be the largest disclosure yet under the court-ordered release under the Freedom of Information Act.
State spokesman Mark Toner said around 150 emails in the tranche slated for release Monday night will be redacted, but said none of the information deemed classified in the ongoing interagency review of messages on Clinton's private server was marked as classified at the time it was sent.
"We have upgraded a number of these," Toner said. The Associated Press reported Monday that the redacted material in the latest tranche of emails is classified at the "confidential" level, not higher levels such as "top secret."
Another 63 messages from prior disclosures have been redacted because reviewers deemed information classified, but State and Clinton's campaign have said that no information Clinton sent or received was marked classified at the time.
