Alternate Title: NSDD 19: Protection of Classified National Security Council and Intelligence Information
"Unauthorized disclosure of classified information under the jurisdiction of the National Security Council and of classified intelligence reports is a problem of major proportions within the U.S. Government. The Constitution of the United States provides for the protection of individual rights and liberties, including freedom of speech and freedom of the press, but it also requires that government functions be discharged efficiently and effectively, especially where the national security is involved. As President of the United States, I am responsible for honoring both Constitutional requirements, and I intend to do so in a balanced and careful manner. I do not believe, however, that the Constitution entitles government employees, entrusted with confidential information critical to the functioning and effectiveness of the Government, to disclose such information with impunity. Yet this is precisely the situation we have. It must not be allowed to continue." National Security Decision Directive 19 (NSDD 19) sets forth policy on the dicslosure of classified National Security Council information in regards to contacts with the media, access to classified NSC information, and investigations into unauthorized disclosures of NSC information.
