to shape an August 2002 opinion from the Department of Justice's Office of Legal Counsel (OLC) that said torture might be justified in some cases, although John Yoo, author of many of the "Torture Memos", dismissed the notion of Addington's authorship of Department of Justice memos as "so erroneous as to be laughable." US Army Colonel Lawrence Wilkerson, who served as Colin Powell's chief of staff when he was Chairman of the Joint Chiefs of Staff—at the same time Addington was Cheney's personal counsel as Secretary of Defense—and then later when Powell was Secretary of State, stated in an in-depth interview regarding extraordinary measures taken post 9/11: "The man who, to me, brings all of this together more than Cheney himself, because he has one foot in the legal camp—and I must admit it's a fairly brilliant foot—and he has one foot in the operator camp, that's David Addington." Press reports also state that Addington reportedly took a leading role in pressing for the use of torture (so-called "enhanced interrogation techniques") for interrogations when a delegation of top Bush administration attorneys traveled to the Guantanamo Bay detention camp in September 2002 to observe operations there, although Addington said that he could not recall this in his sworn House Judiciary Committee testimony. In congressional testimony, Addington has emphasized that "people out in the field, particularly the folks at the CIA, would not have engaged in their conduct and the head of the CIA would not have ordered them to engage in that conduct without knowing that the Attorney General of the United States or his authorized designee, which is what OLC is, has said this is lawful and they relied on that." The Senate Select Committee on Intelligence released a narrative concerning the Office of Legal Counsel opinions on interrogations on April 17, 2009. The 6,700-page Senate Intelligence Committee report on CIA torture, released in 2016, found the use of torture was both ineffective for gathering intelligence and had damaged America's standing in the world. Some press reports indicate that Addington advocated scaling back the authority of lawyers in the uniformed services; Addington in fact advocated merely that the civilian general counsels of the military departments be recognized as the chief legal officers of those departments.
