On Monday, over 2,000 people packed into Riverside Church in Manhattan to celebrate the 20th anniversary of Democracy Now! It was an historic occasion in part because it marked the first time Noam Chomsky and Harry Belafonte appeared on stage together in conversation. The two have been longtime champions of social justice. Chomsky is a world-renowned political dissident, linguist and author who gained fame in the 1960s for his critique of the Vietnam War and U.S. imperialism. He is institute professor emeritus at Massachusetts Institute of Technology, where he has taught for more than 50 years. Harry Belafonte is a longtime civil rights activist who was an immensely popular singer and actor. He was one of Martin Luther King’s closest confidants and helped organize the March on Washington in 1963.
