The Obama administration has barred officials at 17 agencies from speaking to journalists about unclassified intelligence-related topics without permission, according to a newly disclosed directive. The directive, issued by James R. Clapper Jr., the director of national intelligence, also requires the agencies' employees to report any unplanned contact with journalists. Officials who violate the directive may be disciplined or fired, the directive says. The directive prohibits unauthorized contact with the media about intelligence-related information, including intelligence sources, methods, activities and judgments," without regard to whether it is classified. It says that employees who violate the policy "may be subject to administrative actions that may include revocation of security clearances or termination of employment." At a minimum, the directive adds, any violation of the policy "will be handled in the same manner as a security violation." Mr. Clapper signed the directive on March 20, and it was quietly posted on the office's website last week. The directive limiting contact with reporters was reported Monday by Steve Aftergood, a government secrecy specialist for the Federation of American Scientists. In a blog post, Mr. Aftergood portrayed the directive as seeking to ensure that "the only news about intelligence is to be authorized news." He criticized the policy as going too far, arguing that routine interactions between agency employees and reporters about unclassified matters did not pose a threat to national security, but that limiting them would hurt the public.
