As the diplomatic uproar over National Security Agency spying continues overseas, activists in the United States are holding a protest on Saturday in Washington, D.C. “Stop Watching Us: Rally Against Mass Surveillance” is organized by a coalition of more than 100 groups, companies and public figures. In a statement, Edward Snowden urged supporters to attend, saying: “Today, no telephone in America makes a call without leaving a record with the NSA. Today, no internet transaction enters or leaves America without passing through the NSA’s hands. Our representatives in Congress tell us this is not surveillance. They’re wrong … Join us in sending the message: Stop watching us.”
