Arizona Attorney General Mark Brnovich says county election officials can maintain separate voter databases but are legally required to send voter information to the secretary of state's office.
Brnovich also said in an opinion released Monday that Secretary of State Michele Reagan can't refer public records requests or legal subpoenas to counties since she also maintains the voter rolls.
The opinion also clarified what voter registration information county recorders are required to provide to Reagan's office. Solicitor General Dominic Draye wrote that includes everything, and immediately.
He said that under federal and state law, all 15 recorders must provide names and addresses, cancelled and rejected registrations and records detailing early voting and provisional ballots.
Reagan spokesman Matt Roberts says some counties weren't providing some data and now must.
