PHOENIX (AP) — The board overseeing a southeastern Arizona county whose Republican leaders had hoped to recount all Election Day ballots on Friday delayed certifying the results of last week’s vote after hearing from a trio of conspiracy theorists who alleged that counting machines were not certified.

The three men, or some combination of them, have filed at least four cases raising similar claims before the Arizona Supreme Court since 2021 seeking to have the state’s 2020 election results thrown out. The court has dismissed all of them for lack of evidence, waiting too long after the election was certified or asking for relief that could not be granted, in increasingly harsh language.

But Tom Rice, Brian Steiner and Daniel Wood managed to persuade the two Republicans who control the Cochise County board of supervisors that their claims were valid enough for them to delay the certification until a Nov. 28 deadline.

They claimed the U.S. Elections Assistance Commission allowed certifications for testing companies to lapse, and that voided the certifications of vote tabulation equipment used across the state.

That came despite testimony from the state’s elections director that the machines and the testing company were indeed certified.

“The equipment used in Cochise County is properly certified under both federal and state laws and requirements,” state Elections Director Kori Lorick told the board. “The claims that the SLI testing labs were not properly accredited are false.”

The move is the latest drama in the Republican-heavy county in recent weeks, which started when GOP board members Tom Crosby and Peggy Judd voted to have all the ballots in last week’s election counted by hand to determine if the machine counts were accurate.

Crosby also defended a lawsuit he and Judd filed against the county elections director earlier this week seeking to force the hand-count. They dropped the case against Lisa Marra on Wednesday.

“If our presenters’ request is met by the proof that our machines are indeed legally and lawfully accredited, then indeed we should accept the results,” Crosby said. “However, if the machines have not been lawfully certificated, then the converse is also true. We cannot verify this election now.”

Crosby and Judd then voted to delay certification, with Crosby saying he believed Wood, Steiner and Rice needed to be provided proof since they were “the experts.”

Democratic Supervisor Ann English was powerless to overrule them.

The delay potentially jeopardizes state certification, set for Dec. 5, and at least one statewide recount.

Lorick issued a statement after the vote vowing legal action to force the board to accept the results. Under Arizona law the formal election canvass can’t be changed by the elected county boards — their only role is to accept the numbers as they are tallied by their elections departments.

“If they fail to do so, the Secretary (of State) will use all available legal remedies to compel compliance with Arizona law and protect Cochise County voters’ rights to have their votes counted,” Lorick said.

All 15 Arizona counties face the same Nov. 28 deadline, but there is no sign others are considering similar defiance.

Once the state certifies the results Dec. 5, there will be a recount in at least one statewide race.

That contest, between Republican Abraham Hamadeh and Democrat Chris Mayes for attorney general, is so close that a recount is certain. As of Friday night, Mayes was less than 600 votes ahead with fewer ballots remaining to be counted than the margin for a mandatory recount, which will be about 12,500 votes.

“It’s going to be close, and every vote matters,” Mayes said in a brief interview. “And obviously we’re headed into a recount, one way or another.”

One other statewide race also is within the margin for a recount, but incumbent Superintendent of Public Instruction Kathy Hoffman conceded to Republican Tom Horne on Thursday. Horne is a former schools chief who served two years as attorney general before losing the 2014 primary. He was more than 9,000 votes ahead on Friday.

Horne criticized Hoffman for embracing progressive teaching and promised to shut down any hint of “critical race theory,” which is not taught in state schools but is a hot-button issue for social conservatives.

Judd had said Wednesday she would move to clear the way for the state recount.

“We’ve had to step back from everything we were trying to do and say, OK, we’ve got to let this play out,” Judd told The Associated Press. “Because it’s the last thing we want to do to get in (Marra’s) way.”

There has been no evidence of widespread fraud or manipulation of voting machines in 2020 or during this year’s midterm elections.

Arizona recount laws were changed this year. The previous margin for a mandatory recount was 1/10 of 1%. It is now 0.5%.
