WASHINGTON (AP) — Civil rights leader John Lewis on Thursday dismissed Democratic presidential candidate Bernie Sanders' 1960s work on racial equality, saying, I never saw him. The Georgia congressman — a stalwart of the Freedom Rides through the South, lunch counter sit-ins and the 1963 March on Washington — raised questions about Sanders' involvement in the movement when the Vermont senator was a college student. Lewis has endorsed Sanders' chief rival, Hillary Clinton, and his comments come at a critical time as the two White House contenders focus on the upcoming primaries in Southern states with predominantly African-American Democratic voters. On his campaign website, Sanders says he has a "long history of fighting for social equality and the rights of black Americans — a record that goes back to the early 1960s."
