The Maricopa County Board of Supervisors approved a plan to spend $2.8 million to replace election equipment it deemed disqualified for reuse after the GOP-led Arizona Senate subpoenaed machines for an audit of the 2020 general election.

County officials voted 5-0 on Wednesday for the purchase after Arizona Secretary of State Katie Hobbs warned the machines would be decertified after Cyber Ninjas, a Florida-based private firm criticized for a lack of prior audit experience, got access to them for the controversial review.
