A crowd of about 5,000 people, chanting "stop spying, stop lying" and "hey, ho, mass surveillance has got to go," marched through Washington, D.C., Saturday to protest the U.S. National Security Agency's mass surveillance programs unveiled in press reports this year. Protesters, from a seemingly wide range of political beliefs, called on the U.S. Congress and President Barack Obama to end mass data collection and surveillance by the NSA.
