FILE - In this April 11, 1967 file photo, U.S. Sen. Robert F. Kennedy, D-NY, tours the Mississippi Delta near Greenville, Miss., on an anti-poverty investigation. Marian Wright Edelman, second from right, visited poor people in the Mississippi Delta with Kennedy and other U.S. Senators. Wright returns to Mississippi July 12, 2017, to examine how poverty affects people's lives, much like Sen. Robert F. Kennedy did 50 years ago. (AP Photo/stf, FILE)
