This document is the United States' response to a motion opposing the government's request to resume bulk data collection under Section 215 of the Patriot Act for a 180-day transition period. The response argues that Section 215, as amended by the USA FREEDOM Act, authorizes the Foreign Intelligence Surveillance Court to approve the bulk production of call detail records for 180 days as the government transitions to the new targeted production procedures under the USA FREEDOM Act. The response also argues this bulk collection is consistent with the Fourth Amendment.
