Proponents of reform to the National Security Agency‘s data collection program say that any reforms must include changes to the Electronic Communications privacy Act, a bill that was originally passed in 1986 and has not been updated to address changing technology.

Sens. Patrick Leahy, D-Vt., and Mike Lee, R-Utah, introduced a bill in April to amend the ECPA in order to update the law’s privacy protections to relate to 21st century technologies.
