WASHINGTON (AP) — A watchdog group sued Vice President Dick Cheney on Monday, seeking a court order that he comply with the Presidential Records Act.

The group that sued is concerned that Cheney will argue that his records are not subject to the post-Watergate law aimed at safeguarding White House records for eventual release to the public.

The lawsuit by Citizens for Responsibility and Ethics in Washington stems from Cheney's position that his office is not part of the executive branch of government.
