was waterboarded 183 times while being interrogated by the CIA. Pakistani intelligence agents say Mohammed was carrying a letter from bin Laden at the time of his arrest, but there is no evidence he knew bin Laden's whereabouts. By this point, any information Mohammed had would have been years out of date. After being subjected to repeated waterboarding, Mohammed claimed participation in thirty-one terrorist plots. On 15 June 2009, in response to a lawsuit by the ACLU, the government was forced to disclose a previously classified portion of a CIA memo written in 2006. It recounted Mohammed's telling the CIA that he "made up stories" to stop from being tortured. Legal experts cast serious doubt as to the validity of Mohammed's "confessions" as being false claims, and human rights activists raised serious concerns over the "sham process" of justice and use of torture. During a radio interview on 24 October 2006, with Scott Hennen of radio station WDAY, Vice President Dick Cheney agreed with the use of waterboarding. The administration later denied that Cheney had confirmed the use of waterboarding, saying that U.S. officials do not talk publicly about interrogation techniques because they are classified. White House Press Secretary Tony Snow claimed that Cheney was not referring to waterboarding, despite repeated questions refused to specify what else Cheney was referring to by a "dunk in the water", and refused to confirm that this meant waterboarding. On 13 September 2007, ABC News reported that a former intelligence officer stated that Khalid Sheikh Mohammed had been waterboarded in the presence of a female CIA supervisor. On 2 June 2010, while speaking to the Economic Club of Grand Rapids, Michigan, former President Bush publicly confirmed his knowledge and approval of waterboarding Mohammed, saying "Yeah, we waterboarded Khalid Sheikh Mohammed...I'd do it again to save lives." Obama administration President Barack Obama banned the use of waterboarding and several other interrogation methods in January 2009. He reported that U.S. personnel must stick to the Army Field Manual guidelines. In early April 2009, the Obama administration released several classified Justice Department memos from the George W. Bush administration that discussed waterboarding. Obama opposed prosecuting CIA personnel who committed waterboarding while relying on legal advice provided by their superiors. The American Civil Liberties Union has criticized his stance. In early April 2009, news reports stated that Obama would support an independent investigation over the issue as long
