At least nine Bush administration officials refused to cooperate with various Justice Department investigations during the final days of the Bush presidency, according to public records and interviews with federal law enforcement officials and many of the officials and their attorneys. In addition, two U.S. senators, a congresswoman, and the chief of staff to one of them, also refused to cooperate with the same investigations.
In large part because of that noncooperation, Justice Department officials sought criminal prosecutors in at least two cases so far to take over their investigations so that they can compel the testimony of many of those officials to testify through the use of a federal grand jury.
With the stakes now escalating for both sides -- the possibility of grand jury subpoenas for recalcitrant witnesses and the specter of senior government officials invoking their Fifth Amendment right to self-incrimination -- it remains unclear whether and how many of them will continue to defy investigators.
