For four years, Vice President Dick Cheney has resisted routine oversight of his office’s handling of classified information, and when the National Archives unit that monitors classification in the executive branch objected, the vice president’s office suggested abolishing the oversight unit, according to documents released yesterday by a Democratic congressman.

The Information Security Oversight Office, a unit of the National Archives, appealed the issue to the Justice Department, which has not yet ruled on the matter.

Representative Henry A. Waxman, Democrat of California and chairman of the House Committee on Oversight and Government Reform, disclosed Mr. Cheney’s effort to shut down the oversight office. Mr. Waxman, who has had a leading role in the stepped-up efforts by Democrats to investigate the Bush administration, outlined the matter in an eight-page letter sent Thursday to the vice president and posted, along with other documentation, on the committee’s Web site.

Officials at the National Archives and the Justice Department confirmed the basic chronology of events cited in Mr. Waxman’s letter.
