Biden, Jr. of Delaware, together secured enactment of landmark legislation to fundamentally reform the U.S. foreign policy institutions for the post-Cold War world—shutting down two obsolete federal agencies (United States Information Agency (USIA) and Arms Control and Disarmament Agency ACDA)) and merging their functions into the Department of Stateand bringing a third (United States Agency for International Development (USAID)) under the direct control of the Secretary of State."
