The Providence branch of the NAACP is celebrating its 100th year and planned to hear from civil rights leader John Lewis, congressman from Georgia. The group was to give Lewis its Roy Wilkins Lifetime Achievement Award during a celebration Friday evening in Providence. He will also deliver a keynote address. Lewis is a Democrat and has represented Georgia’s Fifth District in Congress since 1987. He was a freedom rider and a civil rights leader in the 1960s and was severely beaten while marching for voting rights. The NAACP is also honoring Mayor James Diossa of Central Falls, Family Court Magistrate Rossi Harris, and other community activists.
