Meanwhile, a Justice Department investigation into the Bush administration’s domestic spy program has been closed because the National Security Agency refused to grant investigators security clearances. According to the Office of Professional Responsibility, investigators had been asking for the clearances since January, but were only told their requests had been denied this week. New York Democratic Congressmember Maurice Hinchey called for a probe of the NSA’s denial, saying: “The Bush administration cannot simply create a Big Brother program and then refuse to answer any questions on how it came about and what it entails.”
