Officials in Arizona’s largest county and Dominion Voting Systems on Monday announced their defiance of the state Senate’s latest round of subpoenas, continuing a feud that started last year.

Maricopa County’s Board of Supervisors decided in a closed session not to deliver any more election-related materials or information to the Arizona Senate, despite a judge earlier this year ruling subpoenas from the body lawful.

In a 6-page letter to Kory Langhofer, attorney for Arizona Senate President Karen Fann, county officials said that auditors hired by Fann already have some of the information they seek and will not receive the rest at this time, or ever.

Fann sought ballot envelopes or ballot envelope images; user names, passwords, and security keys for election machines; voter records; routers or router images; and splunk logs.

Allister Adel, the county’s attorney, told Fann that the county has already provided ballot images. The county recorder, Stephen Richer, will produce the ballot envelopes themselves, but only if there’s confirmation “that appropriate security measures are in place,” Adel wrote. Richer will also work to produce voter records.

The county does not have user names, passwords, or security keys requested for the machines, officials claim. Moreover, the request is moot because the machines have been returned to the county, they say. Also, they are refusing to hand over routers or router images, or splunk logs, claiming that doing so would be a security risk.
