US Representative John Conyers Jr., Pentagon Papers whistleblower Daniel Ellsberg and actor Maggie Gyllenhaal join a chorus of prominent voices calling for an end to mass suspicionless surveillance by the National Security Agency (NSA) in a new short video released by the coalition.

The video is a call to action released in support of the Stop Watching Us: Rally Against Mass Surveillance being held in Washington, DC, on Saturday, October 26, the twelfth anniversary of the Patriot Act. Formed in June 2013, the coalition comprises more than 100 public advocacy organizations from across the political spectrum demanding that Congress investigate the full extent of the NSA’s spying programs.

The protest should be the largest privacy protest in the history of the republic. The demand is for a full congressional investigation of America’s surveillance programs, reform to federal surveillance law and accountability from public officials responsible for hiding this surveillance from lawmakers and the public. Sign the coalition’s petition and find out how you can support the campaign, whether or not you can get to DC on October 26.
