Arizona’s Maricopa Country has announced that it will replace all voting machines following the GOP election audit.

The Hill reports:

The Maricopa County Board of Supervisors released its response to a May letter from Arizona Secretary of State Katie Hobbs (D), in which she expressed concerns “regarding the security and integrity of these machines, given that the chain of custody, a critical security tenet, has been compromised and election officials do not know what was done to the machines while under Cyber Ninjas’ control.”

In response, the county told Hobbs it “shares your concerns” and added that the board acknowledges the secretary of state’s “authority as Arizona’s Chief Election Officer to determine what equipment is acceptable for use in Arizona’s elections.”

“Accordingly, I write to notify you that Maricopa County will not use the subpoenaed election equipment in any future election,” Monday’s letter added.

In a press release announcing the decision, the county vowed to “never use equipment that could pose a risk to free and fair elections.”
