Sen. Lindsey Graham has joined a number of senators voicing concern over President Bush’s nominee for U.S. Attorney General, Michael Mukasey, and his position on the harsh interrogation technique known as “waterboarding.” Graham, who sits on the judiciary committee, is hesitant to approve a candidate that condones the practice – seen by many as torture.

“I am convinced as an individual senator, as a military lawyer for 25 years, that waterboarding … does violate the Geneva Convention, does violate our war crimes statute, and is clearly illegal,” Graham told “Face the Nation.”

“I think it would serve the attorney general nominee well to embrace that concept,” Graham said.

Asked if he would oppose Mukasey if the nominee refused to do so, Graham said, “If he does not believe that waterboarding is illegal, then that would really put doubts in my own mind.” [Reuters]

The waterboarding technique, according to a 2005 ABC News investigation of CIA practices, involves “a prisoner, who is bound and gagged, and has water poured over him to make him think he is about to drown.” Former Attorney General Alberto Gonzalez said the legality of waterboarding under the Geneva Convention was “not so clear.”
