Dear General Nakasone,
We write to urge that you provide a public description, consistent with protection of sources and methods, of the current status of the call detail record (CDR) program under Title V of the Foreign Intelligence Surveillance Act (FISA). On June 28, 2018, NSA publicly announced that it had obtained from telecommunications service providers CDRs it was not authorized to receive, and that NSA had begun deleting all CDRs acquired since 2015. Since then, there have been no public updates from NSA. A public status report will resolve the current confusion, demonstrate the NSA's commitment to transparency, and inform Congress's deliberations about the possible reauthorization of the program later this year.
Thank you for your attention to this important matter.
