A US congressman, John Lewis, was 23 years old when he participated in the historic 1963 civil rights “March on Washington” led by Dr. Martin Luther King Jr. Half a century later, journalist Bill Moyers asked Lewis how he was affected by Dr. King’s I Have A Dream speech that day. Mr. Lewis replied, “You couldn’t leave after hearing him speak and go back to business as usual. You had to do something, you had to act. You had to move. You had to go out and spread the good news.”
