The NBA mourned the passing of civil rights leader and long-time United States congressman Rep. John Lewis, who died Friday of pancreatic cancer. "The NBA Family mourns the passing of Rep. John Lewis, a great American hero and icon of the civil rights movement and the fight for equality who helped galvanize opposition to racial segregation and social injustice," the league said. Los Angeles Lakers standout LeBron James joined many other NBA stars who took to social media to pay their respects.
