WASHINGTON, May 6 (Xinhua) -- A U.S. House panel subpoenaed several former and present high-ranking Bush administration officials on Tuesday to testify on the issue of alleged torture of terror detainees.
Among them are John Yoo, a former top Justice Department official who authored hugely controversial memos on interrogation techniques used on detainees, and Vice President Dick Cheney's chief-of-staff David Addington, who was heavily involved in preparing the memos.
Former Attorney General John Ashcroft, former Under Secretary of Defense Douglas Feith and former Assistant Attorney General DanLevin also agreed to testify on the issue before the House Judiciary Committee's subcommittee on the Constitution, Civil Rights and Civil Liberties.
The subcommittee said former CIA Director George Tenet is stillin negotiations for testimony.
Subcommittee chairman Jerrold Nadler said torture is "un-American and yet it has been used by this government against those in our custody and control."
"Now we know that these so-called 'enhanced' interrogation techniques were approved at the highest levels of government. Torture and cruel, inhuman, or degrading treatment, besides being contrary to American values and traditions, have proven to be an ineffective means to obtaining actionable intelligence," he added.
