DOJ OIG Releases Executive Summary of its Classified Report on the FBI's Use of Pen Registers and Trap Devices under FISA


The Department of Justice (DOJ) Office of the Inspector General (OIG) announced today the release of a public Executive Summary of the OIG’s classified report entitled, The Federal Bureau of Investigation’s Use of Pen Register and Trap and Trace Devices under the Foreign Intelligence Surveillance Act in 2007 through 2009. The OIG issued the classified report to DOJ leadership offices, the Federal Bureau of Investigation (FBI), the Office of the Director of National Intelligence, and the relevant Congressional oversight and intelligence committees on May 28, 2015. At that time, the summary released today was under review by the DOJ, FBI, and Intelligence Community; the OIG received the final results of that review yesterday.

The Executive Summary released today provides an overview of the results of the OIG’s review of the FBI’s use of pen registers and trap and trace devices – which we refer to collectively as pen registers – under the Foreign Intelligence Surveillance Act (FISA). The summary describes the methodology the OIG used to conduct the review and provides some legal background about pen registers. The summary also describes the OIG’s findings regarding the FBI’s storage and handling of pen register information and the compliance process relating to the use of pen registers. Information from the OIG's full report that the FBI and the Intelligence Community determined is classified or "for official use only" could not be included in today's 5-page summary.

The Executive Summary can be found on the OIG’s website at the following link: https://oig.justice.gov/reports/2015/o1506.pdf
