David Addington
David Spears Addington (born January 22, 1957) is an American lawyer and former government official who served as legal counsel (2001–2005) and chief of staff (2005–2009) to Vice President Dick Cheney.[1] Addington graduated summa cum laude from Georgetown University's School of Foreign Service in 1978 and earned a Juris Doctor with honors from Duke University School of Law in 1981.[2] His early career included roles as an attorney in the CIA's Office of General Counsel, Republican staff director for the Senate Select Committee on Intelligence, and special assistant to President Ronald Reagan for legislative affairs.[3] During George H. W. Bush's administration, Addington was nominated to serve as General Counsel of the Department of Defense under Secretary Cheney.[1] In the George W. Bush administration, Addington played a central role in advancing expansive interpretations of presidential authority, including the unitary executive theory, and in developing legal frameworks for post-9/11 national security measures such as enhanced interrogation techniques and warrantless surveillance programs.[4][5] These efforts, often conducted behind the scenes, significantly bolstered the vice president's influence and the executive branch's operational latitude amid ongoing threats from terrorism.[6] Following his White House tenure, Addington held senior positions at the Heritage Foundation as vice president and deputy chief operating officer before becoming senior vice president, general counsel, and chief legal officer at the National Federation of Independent Business.[7]
