Secrecy and Foreign Policy, Robert Pallitto, December 8, 2006, Foreign Policy In Focus: “Since the beginning of the republic, U.S. presidents have used some form of secrecy in the course of governing. In the wake of the Watergate scandal, congressional hearings in the 1970s and the disclosure of covert U.S. programs of assassination and destabilization overseas temporarily reduced the scope of secret activities sponsored by the executive branch. From the 1980s on, however, presidents have come to rely increasingly on secrecy-related practices. Though the U.S. Constitution does not explicitly grant executive secrecy in the list of Article II powers, presidents have increased their powers through legislation, the federal courts’ recognition of legal defenses to conceal information, and responses to the ongoing threat of terrorism.”
