Question presented	Republican National Committee, Petitioner v. Mi Familia Vota, et al.1. Does the National Voter Registration Act or a federal consent decree prohibit Arizona from requiring voter-registration applicants to produce "satisfactory evidence" of U.S. citizenship when registering with a state registration form? 2.

Warren Petersen, President of the Arizona Senate, et al., Petitioners v. Mi Familia Vota, et al.1. Does the National Voter Registration Act or a federal consent decree prohibit Arizona from requiring voter-registration applicants to produce “satisfactory evidence” of U. S. citizenship when registering with a state registration form? 2. Does the National Voter Registration Act prohibit Arizona from implementing a program within 90 days of a federal election to cancel the registrations of voters who are not U. S. citizens?
Summary	Republican National Committee, Petitioner v. Mi Familia Vota, et al.This pending case concerns Arizona laws requiring people who use the state voter-registration form to provide documentary proof of U.S. citizenship and directing officials to cancel registrations when information confirms that a registrant is not a citizen. The Court will decide whether federal voter-registration law or a prior consent decree blocks those measures, including cancellations made within 90 days of a federal election.	Warren Petersen, President of the Arizona Senate, et al., Petitioners v. Mi Familia Vota, et al.Arizona legislative leaders ask the Court to review a Ninth Circuit decision that blocked parts of Arizona’s voter-registration and mail-voting rules requiring documentary proof of citizenship or residence. The case also concerns the Ninth Circuit’s ruling that a related Arizona law directing election officials to check databases for potentially ineligible voters was enacted with intentional discrimination.
