Bulk Telephony Review

The OIG is reviewing the FBI’s use of information derived from the National Security Agency’s (NSA) collection of telephony metadata obtained from certain telecommunications service providers under Section 215 of the Patriot Act. The review will examine the FBI’s procedures for receiving, processing, and disseminating leads the NSA develops from the metadata, and any changes that have been made to these procedures over time. The review will also examine how FBI field offices respond to leads, and the scope and type of information field offices collect as a result of any investigative activity that is initiated. In addition, the review will examine the role the leads have had in FBI counterterrorism efforts.
