Georgia's voter registration law requiring proof of citizenship is similar to one in Arizona that has been struck down by the U.S. Supreme Court.

Secretary of State Brian Kemp says he's disappointed with Monday's ruling that states cannot take action on their own to require prospective voters to prove citizenship.

The Supreme Court says federal law precludes states from asking for proof since the National Voter Registration Act of 1993 does not require such documentation. The justices did leave open the possibility that states could still seek approval from the federal government or federal courts to do so.

Kemp says Georgia's citizenship requirement "ensures the integrity of our voting process" and he will be working with the governor, the General Assembly and the attorney general on next steps.
