Two of Arizona’s top election administrators have issued scathing indictments of a contractor who audited millions of ballots cast in the state’s largest county. The two officials are seeking to undercut a final report from Cyber Ninjas, the firm hired by Arizona’s Republican-controlled state Senate, that they say will be marred by deep flaws. Cyber Ninjas is expected to deliver its initial report Monday on the nearly 2.1 million ballots cast in Maricopa County in last year's presidential election.
