Emails from Hillary Clinton’s home server contained information classified at levels higher than previously known, including a level meant to protect some of the most sensitive U.S. intelligence, according to a document obtained by NBC News.
In a letter to lawmakers, the intelligence community’s internal watchdog says some of Clinton’s emails contained information classified Top Secret/Special Access Program, a secrecy designation that includes some of the most closely held U.S. intelligence matters.
Two American intelligence officials tell NBC News these are not the same two emails from Clinton’s server that have long been reported as containing information deemed Top Secret.
Charles McCulllough, the intelligence community’s inspector general, said in a letter to the chairmen of the Senate intelligence and foreign affairs committees that he has received sworn declarations from an intelligence agency he declined to name.
The declarations cover “several dozen emails containing classified information determined by the IC element to be at the CONFIDENTIAL, SECRET and TOP SECRET/SAP information.”
An intelligence official familiar with the matter told NBC News that the special access program in question was so sensitive that McCullough and some of his aides had to receive clearance to be read in on it before viewing the sworn declaration about the Clinton emails.
