Voting rights groups filed an appeal Friday of a judge's order that federal election officials must help Kansas and Arizona enforce state laws requiring new voters to provide documentation proving their U.S. citizenship.

A court filing sent to the 10th U.S. Circuit Court of Appeals challenges a ruling earlier this month by U.S. District Judge Eric Melgren in Wichita. Melgren had ordered the U.S. Election Assistance Commission to immediately modify a national voter registration form to add special instructions requiring proof of citizenship for Kansas and Arizona residents.
