WICHITA, Kan. (AP) — The Kansas secretary of state’s office late Tuesday instructed county officials to put on election rolls the thousands of people who registered at motor vehicle offices without providing proof of U.S. citizenship, but only allow them to vote for federal offices.

The guidelines were issued after the 10th Circuit U.S. District Court of appeals ordered Kansas to begin Tuesday adding more than 18,000 voters whose registrations had been cancelled or suspended.

U.S. District Judge Julie Robinson’s order strikes a blow to a Kansas law that since January 2013 has required voters to provide proof of citizenship.

About 44 percent of Kansas voters register when getting their driver’s licenses under the federal “motor-voter law.”
