U.S. House observes moment of silence for Rep. John Lewis

John Lewis, a pioneer of the civil rights movement and long-time member of the U.S. House of Representatives, died on Friday.

A Democratic member of Congress from Atlanta since 1987, Lewis had announced in December that he had advanced pancreatic cancer. He was 80.

Lewis was a protégé of the Rev. Martin Luther King Jr., whom he met after writing to him when Lewis was just 18. He was the last surviving speaker from the 1963 March on Washington, having stood beside King when he made his "I Have a Dream" speech.
