This letter outlines the ACLU’s position that Congress should use the opportunity presented by the scheduled sunset of the expiring provisions of the Patriot Act to enact far-reaching reforms to surveillance laws. The letter urges opposition to Sen. McConnell’s S. 1357, Sen. Feinstein’s S. 1469, and Sen. Burr’s proposed FISA Improvements Act. The letter also calls for improvements to the USA Freedom Act.
