Meanwhile, the United Nations’s top torture investigator has criticized the Bush administration for defending the use of waterboarding. Manfred Nowak, the UN’s special rapporteur on torture, said, “This is absolutely unacceptable under international human rights law.” Nowak’s comment came one day after CIA Director Michael Hayden acknowledged that three detainees were waterboarded in 2002 and 2003. On Wednesday, White House spokesperson Tony Fratto said that CIA interrogators could use waterboarding again with the President’s approval. Attorney General Michael Mukasey is expected to be questioned about waterboarding today, when he appears before the House Judiciary Committee.
