However, in any unusual case, the request will be presented to the Secretary, Deputy Secretary, or staff or administration head for personal action. When the requested information is of a type which may not be furnished a claimant, the member of Congress shall be advised that the information is furnished to him or her confidentially in his official capacity and should be so treated by him or her. (See 38 U.S.C. 5701 .)
