Months before the Bush administration ends, historians and open-government advocates are concerned that Vice President Cheney, who has long bristled at requirements to disclose his records, will destroy or withhold key documents that illustrate his role in forming U.S. policy for the past 7 1/2 years. In a preemptive move, several of them have agreed to join the advocacy group Citizens for Responsibility and Ethics in Washington in asking a federal judge to declare that Cheney's records are covered by the Presidential Records Act of 1978 and cannot be destroyed, taken or withheld without proper review The goal, proponents say, is to protect a treasure trove of information about national security, the wars in Iraq and Afghanistan, domestic wiretapping, energy policy, and other major issues that could be hidden from the public if Cheney adheres to his view that he is not part of the executive branch. Extending the argument, scholars say, Cheney could assert that he is not required to make his papers public after leaving office. Access to the documents is crucial because he is widely considered to be the most influential vice president in U.S. history, they note. "I'm concerned that they may not be preserved. Whether they've been zapped already, we don't know," said Stanley I. Kutler, an emeritus professor and constitutional scholar at the University of Wisconsin Law School.
