Attorney General Eric Holder is considering whether to appoint a criminal prosecutor to investigate the Bush administration’s interrogation practices involving the CIA. Newsweek reports Holder has become increasingly troubled after reviewing the Bush administration’s interrogation policies. He reportedly told one associate that what he saw in the reports about the treatment of prisoners at the CIA’s black sites “turned my stomach.” Holder is expected to make a decision in the coming weeks and has already discussed several potential candidates to serve as special prosecutor. Holder is considering the probe despite opposition from President Obama, who resisted an effort by congressional Democrats to establish a “truth commission.” Obama has said the nation should be “looking forward and not backwards.” Holder told Newsweek, “I hope that whatever decision I make would not have a negative impact on the President’s agenda. But that can’t be a part of my decision.”
