Stephen A. Cambone (born June 22, 1952) was the first United States Under Secretary of Defense for Intelligence, a post created in March 2003. Cambone first came to the attention of the public at large during the testimony of Major General Antonio Taguba before the U.S. Senate Armed Services Committee, where he disputed the General's statement that prison guards were under the effective control of military intelligence personnel and interrogators. Cambone resigned at the beginning of 2007 and was replaced by James R. Clapper, Jr., former head of the Defense Intelligence Agency (DIA) and the National Geospatial-Intelligence Agency.
