Two towering figures of the American civil rights movement died Friday, a major loss for a nation still grappling with protests and demands for racial equality decades later.
John Robert Lewis died at age 80 after a battle with cancer. Rev. Cordy Tindell "C.T." Vivian died at age 95 of natural causes. They died a day before the birthday of the late Nelson Mandela -- another renown champion of racial equality.
