FILE - In this Oct. 15, 1957 file photo, seven of nine black students walk onto the campus of Central High School in Little Rock, Ark., with a National Guard officer as an escort as other troops watch. More than a half-century after federal troops escorted nine black students into an all-white school, efforts to desegregate Little Rock's classrooms are at another turning point. The state wants to end its long-running payments for desegregation programs, but three school districts that receive the money say they need it to continue key programs. And a federal judge has accused the schools of delaying desegregation so they can keep receiving an annual infusion of $70 million. (AP Photo, Fred Kaufman, File)
