The Arizona Senate may sign a deal for another 2020 election review in Maricopa County following reports that some overseers of the audit are dissatisfied with the process.

The present audit, which includes a review of 2.1 million ballots cast in the state’s November election in the county, has been underway since April 23 at the Veterans Memorial Coliseum in Phoenix, led by the hired firm Cyber Ninjas. Audit liaison, former Secretary of State Ken Bennett, told a reporter with CBS5 News on Thursday that hand counters had gone through more than 800,000 ballots so far. Organizers have said they hope to finish by the end of June.
