The most significant measure is the addition of a new question to the polygraph tests that are used by intelligence agencies. Officials will be asked during the lie-detector tests whether they have disclosed classified information to members of the media, according to Shawn Turner, a spokesman for Clapper.

President Obama’s spy chief is also ordering a review of how the intelligence agencies report contact with members of the media, and will consider changes if he finds the policies inconsistent or insufficient. …

Clapper’s order applies to 16 intelligence agencies, including the CIA, FBI, National Security Agency and Defense Intelligence Agency. He said in a statement that the new measures were the “right thing to do” and “in the interest of our national security.”
