 In November 2002, Haynes wrote a memo for Rumsfeld concerning interrogation techniques to be used at Guantanamo Bay.This followed what were known as the Torture Memos of August 2002, largely written by Yoo and issued by the Office of Legal Counsel to the CIA and DOD, with two signed as well by Jay S. Bybee.These also authorized the use of so-called "enhanced interrogation techniques," brutal interrogation tactics that are widely considered to be torture.
