'Stop Watching Us' Plans for Big DC Rally

Anti-surveillance rally at the National Mall Saturday

In protest of the National Security Agency's surveillance program, thousands of people are expected to march on the National Mall in Washington, D.C., on Saturday.

The rally is being put together by a coalition of diverse groups that have come together under the umbrella organization Stop Watching Us. Their goal: end government spying.

The NSA is one of the biggest surveillance and eavesdropping agencies in the U.S. and was whistleblower Edward Snowden's workplace before he decided to leak some of the agency's top-secret documents to the press in June.
