addresses, employment and former employment), an NSL pursuant to 15 U.S.C. 1681v for a full credit report. Of all the FBI’s NSL authorities, only the last of the FCRA authorities is restricted to use only in international terrorism cases. Finally, the FBI has the authority to issue NSLs pursuant to the National Security Act in the course of investigations of improper disclosure of classified information by government employees. For the first 3 types of NSLs (ECPA, RFPA, FCRA) the NSL must include a certification by an authorized FBI employee that the material is being sought for an authorized national security investigation. That certification is slightly different in the case of a FCRA NSL for a full credit report, where the certification required is that the information is relevant to an international terrorism investigation. The authority to issue an NSL lies at a senior level within the FBI. An NSL can be issued only by an official who ranks not lower than Special Agent in Charge or Deputy Assistant Director. All such officials are career government employees who are members of the Senior Executive Service. Procedurally, an agent or analyst seeking an NSL must prepare a document (an electronic communication or EC) in which the employee lays out the factual predicate for the request. The factual recitation must be sufficiently detailed so that the approving official can determine that the material sought is relevant to an investigation. Additionally, it needs to provide sufficient information concerning the underlying investigation so that reviewing officials can confirm that the investigation is adequately predicated and not based solely on the exercise of First Amendment rights. Finally, the EC includes a “lead” to the Office of the General Counsel (OGC) for purposes of Congressional reporting. OIG Report
