John Lewis, a lion of the civil rights movement whose bloody beating by Alabama state troopers in 1965 helped galvanize opposition to racial segregation, and who went on to a long and celebrated career in Congress, died. House Speaker Nancy Pelosi confirmed Lewis’ passing late Friday night, calling him “one of the greatest heroes of American history.” “All of us were humbled to call Congressman Lewis a colleague, and are heartbroken by his passing,” Pelosi said.
