Republicans on the Senate Select Committee on Intelligence said Friday that they will no longer participate in an investigation into the Bush administration's interrogation policies, arguing that Attorney General Eric H. Holder Jr.'s decision to reexamine allegations of detainee abuse by the CIA would hobble any inquiry.
The intelligence committee launched a review in March of CIA interrogations of high-value detainees such as Khalid Sheik Mohammed, who describes himself as the mastermind of the Sept. 11, 2001, attacks.
