A council of 21 Indian tribes in Arizona, two Arizona citizen groups, and an Arizona state senator filed a motion today in federal court in Kansas to intervene in Kobach v. U.S. Election Assistance Commission (EAC), to oppose a renewed effort by the States of Arizona and Kansas (and their Secretaries of State) to impose these States’ proof-of-citizenship laws on persons applying to register to vote using the federal mail-in registration form. The federal form was created by Congress as part of the National Voter Registration Act of 1993 (NVRA), and was developed by a federal agency, the EAC, pursuant to that statute.
