In his articles, books, and legal memoranda for the U.S. Department of Justice, John Yoo is well known for favoring broad and even exclusive presidential power in the field of national security. Less understood is his dependence on the British model and the prerogatives it extended to the king over external affairs. In his writings, Yoo devotes little attention to the framers' rejection of British executive prerogatives. Even less does he acknowledge their commitment to a republic, a form of government in which sovereign power is vested not in an executive but in the people.
