40 years ago this month 7 blacks and 6 whites, called the Freedom Riders, boarded two public buses in Washington, D.C. and headed to the segregated South. In the second week of their ride, they were beaten and one of their buses fire-bombed. One of the worst attacks came in Montgomery, Alabama. Today, 4 of the original 13 Freedom Riders are on a bus retracing their route of 40 years ago. Lisa talks with Jim Zwerg and John Lewis as they make their way back to Montgomery.
