The RFPA restricts financial institutions’ ability to disclose customers’ financial information, but § 1114 of the RFPA establishes an exception for disclosures “pursuant to requests from a Government authority authorized to conduct foreign counter- or foreign positive-intelligence activities” or the Secret Service “for the purpose of conducting its protective functions.” A precursor to the NSL authorities, section 1114 is an exception that allows banks to provide information voluntarily but does not permit the FBI or any other government agency to compel the disclosure of private information. See Section 1114, P.L. 95-630, 92 Stat. 3706 (1978)
