In 2003, the Defense Secretary Donald Rumsfeld's "Working Group" on interrogations requested that the DIA come up with prisoner interrogation techniques for the group's consideration. According to the 2008 U.S. Senate Armed Services Committee report on the treatment of detainees in U.S. custody, the DIA began drawing up the list of techniques with the help of its civilian employee, a former Guantanamo Interrogation Control Element (ICE) Chief David Becker. Becker claimed that the Working Group members were particularly interested in aggressive methods and that he "was encouraged to talk about techniques that inflict pain."
