From an article by Barton Gellman and Jo Becker in Sunday's Washington Post:
Across the board, the vice president's office goes to unusual lengths to avoid transparency. Cheney declines to disclose the names or even the size of his staff, generally releases no public calendar and ordered the Secret Service to destroy his visitor logs. His general counsel has asserted that "the vice presidency is a unique office that is neither a part of the executive branch nor a part of the legislative branch," and is therefore exempt from rules governing either. Cheney is refusing to observe an executive order on the handling of national security secrets, and he proposed to abolish a federal office that insisted on auditing his compliance.
Richard Cheney--doing his best to make Richard Nixon look like Jimmy Carter.
