The attorney general's startling revelation that President Bush personally blocked a Justice Department investigation into the administration's controversial secret domestic spying programs hasn't gotten the attention it deserves. Bush's move -- denying the requisite security clearances to attorneys from the department's ethics office -- is unprecedented in that office's history. It also comes in stark contrast to the enthusiastic way in which security clearances were dished out to...those charged with finding out who leaked information about the program to the press. Time and time again, Bush and his aides have selectively leaked or declassified secret intelligence findings that served their political agenda -- while aggressively asserting the need to keep secret the information that would tend to discredit them. Some legal experts and members of Congress who have questioned the legality of the NSA program said Bush's move to quash the Justice probe represents a politically motivated interference in Justice Department affairs. The government has in effect curtailed an investigation of itself and hardly anyone has noticed. It has not caused much interest in Congress, or on the nation's editorial pages, or the even in the blogosphere, which takes pride in causing a stir about things that should but nobody else has yet taken notice.
