Wichita ? A federal judge has denied a request to put on hold pending appeal an order requiring Kansas to add to voting rolls for federal elections thousands of eligible voters who did not provide proof of citizenship when registering at motor vehicle offices.

U.S. District Judge Julie Robinson on Wednesday instead extended for an additional two weeks a temporary stay of her order. The move gives Secretary of State Kris Kobach more time to register more than 18,000 eligible voters or request a stay from an appeals court.

Robinson cited the “fair amount of administrative effort” to comply when extending her temporary stay to June 14. The previous deadline was May 31.

Kobach has filed a notice of appeal of the preliminary injunction with the 10th Circuit Court of Appeals.
