LITTLE ROCK, Ark. — Arkansas Attorney General Dustin McDaniel is asking a federal judge to end a desegregation settlement agreement with three Little Rock-area school districts that has required the state to pay the schools more than $1 billion since 1989.

McDaniel on Monday asked a federal judge to release the state from its agreement with the Little Rock, North Little Rock and Pulaski County school districts. The attorney general's office argued that the payments are no longer necessary because North Little Rock and Little Rock have been declared fully unitary — or substantially desegregated — and Pulaski County schools have been declared partially unitary.

A federal appeals court last year ruled that a judge was wrong to cut off desegregation payments because the state had not specifically asked for them to end.
