The U.S. Supreme Court on Thursday vacated rulings on cases involving Texas's Voter ID law and redistricting map, citing its ruling Tuesday that struck down a portion of the Voting Rights Act.

A D.C. court had suspended the Voter ID law and a GOP-drafted redistricting map by citing the portion of the Voting Rights Act that requires preclearance with the U.S. attorney general or federal judges for electoral changes in certain areas with a history of racial discrimination. After the court struck down a portion of the law on Tuesday, those rulings effectively were rendered moot.
