as it would be bipartisan. On 23 April 2009, White House Press Secretary Robert Gibbs stated that the administration had changed its position and no longer supported such an idea. The topic was the subject of heated internal debate within the White House. National Intelligence Director Dennis Blair has stated that "high value information" came from waterboarding certain prisoners during the George W. Bush administration. He also commented that he could not know for sure whether or not other interrogation methods would have caused them to talk, had they been tried. In an administration memo that was publicly released, he wrote, "I do not fault those who made the decisions at that time, and I will absolutely defend those who carried out the interrogations within the orders they were given." An April poll by Rasmussen Reports found that 77 percent of voters had followed the story in the media and that 58 percent believed that releasing the memos compromised American national security. On the issue of a further investigation, 58 percent disagreed while 28% agreed. Obama detailed his view on waterboarding and torture in a press conference on 29 April 2009.

Former Attorney General Michael Mukasey criticized the Obama administration for denying future missions the intelligence capability that made the raid possible: "Acknowledging and meeting the need for an effective and lawful interrogation program, which we once had, and freeing CIA operatives and others to administer it under congressional oversight, would be a fitting way to mark the demise of Osama bin Laden." CIA Director Leon Panetta, who supervised the operation that found and killed bin Laden, stated in an interview with NBC reporter Brian Williams: "...they used these enhanced interrogation techniques against some of these detainees. But I'm also saying, that the debate about whether we would have gotten the same information through other approaches, I think, is always going to be an open question." Republican Senator John McCain, in a Washington Post opinion piece, disputed Mukasey's account, saying: In December 2014, the Senate Select Committee on Intelligence issued a declassified 500-page summary of its still-classified 6,700 page report on the Central Intelligence Agency (CIA) Detention and Interrogation Program. The report concluded that "the CIA's use of
