Occasionally an informant will provide information only in confidence; i.e., they
            do not want the claimant or beneficiary or other person with whom we might expect
            to discuss the information to know the source of our knowledge or possibly even the
            fact that we possess it. Inform the person making the request that we cannot promise
            that we will not disclose the information. For more information regarding confidentiality
            and disclosure, see GN 03301.025.
