The document states: A U.S. official has clarified that the "183" number represents the number of times water was poured onto Mohammed's face—not the number of times the CIA waterboarded him. According to a 2007 Red Cross report, Khalid Sheikh Mohammed was subjected a total of "five sessions of ill-treatment."

. Mohammed said that he had provided a lot of false information, which he had supposed the interrogators wanted to hear, in order to stop the mistreatment. In the 2006 interview with the Red Cross, Mohammed claimed to have been waterboarded in five different sessions during the first month of interrogation in his third place of detention. While the Justice Department memos did not explain exactly what the numbers represented, a U.S. official with knowledge of the interrogation programs explained the 183 figure represented the number of times water was applied to the detainee's face during the waterboarding sessions, rather than separate sessions.
