Cheney has refused to cooperate with a government office responsible for safeguarding national security information, and is seeking to abolish the office altogether. Reagan signed the executive order to protect such information.
He asserts he does not have to comply with the presidential order requiring cooperation because the Information Security Oversight Office is "not an entity within the executive branch". His office last complied with the order in 2002.
His staff blocked the department from inspecting his office in 2004, an unprecedented action. The ISOO has asked Alberto Gonzales to resolve this conflict. So far, the Justice Department has done nothing. Henry Waxman is investigating.
