The sponsor of Arizona's controversial immigration law faces a recall election after opponents collected more than 10,000 voter signatures.
County Elections Director Karen Osborne says her office is certifying that the petitions have 10,365 valid signatures of voters from state Sen. Russell Pearce's legislative district in the Phoenix suburb of Mesa.
They needed 7,756 signatures to force a recall election.
The secretary of state issued its own certification later Friday. It's now up to Gov. Jan Brewer to formally call for the election.
Pearce, a Republican, is best known for sponsoring immigration measures including the 2010 enforcement law known as SB1070. A judge has placed key provisions of that measure on hold while they're challenged in court.
