Presidential directive
In the United States, a presidential directive, or executive action, is a written or oral instruction or declaration issued by the president of the United States, which may draw upon the powers vested in the president by the Constitution of the United States, statutory law, or, in certain cases, congressional and judicial acquiescence. Such directives, which have been issued since the earliest days of the federal government, have become known by various names, and some have prescribed forms and purposes.
