Republican officials in a rural Arizona county refused on Monday to certify the 2022 election, despite no evidence of anything wrong with the count, amid pressure from prominent Republicans to reject results showing Democrats winning top races.

State election officials have said they will sue Cochise County if the board of supervisors misses Monday’s deadline to approve the official tally of votes, known as the canvass. The two Republican county supervisors delayed the canvass vote until hearing once more about concerns over the certification of ballot tabulators, though election officials have repeatedly said the equipment is properly approved.

Democratic election attorney Marc Elias pledged on Twitter to sue the county. Democratic Secretary of State Katie Hobbs’s office had previously said it would sue if the county missed the deadline.

“The Board of Supervisors had all of the information they needed to certify this election and failed to uphold their responsibility for Cochise voters,” Sophia Solis, a spokeswoman for Hobbs, said in an email.

Election results have largely been certified without issue in jurisdictions across the country. That’s not been the case in Arizona, which was a focal point for efforts by former President Donald Trump and his allies to overturn the 2020 election and push false narratives of fraud.

Officials in a northeastern Pennsylvania county where paper shortages caused Election Day ballot problems deadlocked Monday on whether to report official vote tallies to the state, effectively preventing their certification of the results.

Arizona was long a GOP stronghold, but this month Democrats won most of the highest profile races over Republicans who aggressively promoted Trump’s 2020 election lies. Kari Lake, the GOP candidate for governor who lost to Hobbs, and Mark Finchem, the candidate for secretary of state, have refused to acknowledge their losses.

They blame Republican election officials in Maricopa County, the state’s largest, including metro Phoenix, for a problem with some ballot printers. Officials in Maricopa County said everyone had a chance to vote and all legal ballots were counted.

Navajo, a rural Republican-leaning county, and Coconino, which is staunchly Democratic, voted to certify on Monday. In conservative Mohave and Yavapai counties, supervisors voted to canvass the results despite their own misgivings and several dozen speakers urging them not to.

“Delaying this vote again will only prolong the agony without actually changing anything,” said Mohave County Supervisor Hildy Angius, a Republican. The county last week delayed its certification vote to register a protest against voting issues in Maricopa County.

In Cochise County, GOP supervisors demanded last week that the secretary of state prove vote-counting machines were legally certified before they would approve the election results. On Monday, they said they wanted to hear again about those concerns.

State Elections Director Kori Lorick has said the machines are properly certified for use in elections. She wrote in a letter last week that the state would sue to force Cochise County supervisors to certify, and if they don’t do so by the deadline for the statewide canvass on Dec. 5, the county’s votes would be excluded. That move threatens to flip the victor in at least two close races — a U.S. House seat and state schools chief — from a Republican to a Democrat.

There are two companies that are accredited by the U.S. Election Assistance Commission to conduct testing and certification of voting equipment, such as the electronic tabulators used in Arizona to read and count ballots.

Conspiracy theories surrounding this process surfaced in early 2021, focused on what appeared to be an outdated accreditation certificate for one of the companies that was posted online. Federal officials investigated and reported that an administrative error had resulted in the agency failing to reissue an updated certificate as the company remained in good standing and underwent audits in 2018 and in early 2021.

Officials also noted federal law dictates the only way a testing company can lose certification is for the commission to revoke it, which did not occur.

Lake has pointed to problems on Election Day in Maricopa County, where printers at some vote centers produced ballots with markings that were too light to be read by on-site tabulators. Lines backed up amid the confusion, and Lake says an unknown number of her supporters may have been dissuaded from voting as a result.

She filed a public records lawsuit last week, demanding the county produce documents shedding light on the issue before voting to certify the election on Monday. Republican Attorney General Mark Brnovich also demanded an explanation ahead of the vote.

The county responded on Sunday, saying nobody was prevented from voting, and 85% of vote centers never had lines longer than 45 minutes. Most vote centers with long lines had others nearby with shorter waits, county officials said.

The response blamed prominent Republicans, including party chair Kelli Ward, for sowing confusion by telling supporters on Twitter not to place their ballots in a secure box to be tabulated later by more robust machines at county elections headquarters.

The county said that just under 17,000 Election Day ballots were placed in those secure boxes and all were counted. Only 16% of the 1.56 million votes cast in Maricopa County were made in-person on Election Day. Those votes went overwhelmingly for Republicans.

Maricopa County supervisors heard for hours from dozens of people angry about the election, some demanding the county hold a revote, though there is no provision in state law allowing that. Supervisors unanimously approved the canvass.

“This was not a perfect election,” said Board of Supervisors Chairman Bill Gates, a Republican. “But it was safe and secure. The votes have been counted accurately.”

Meanwhile, Maricopa County Superior Court Judge Randall Warner said he would decide in the next few days whether to allow an election challenge by Abraham Hamadeh, the Republican candidate for Arizona attorney general, to move ahead.

Warner, who was appointed to the court in 2007 by Democratic Gov. Janet Napolitano, spoke after a Monday afternoon hearing. Hamadeh filed the lawsuit earlier this month against his opponent, Democrat Kris Mayes, who holds a 510-vote lead in the race, along with every county recorder in Arizona and Secretary of State Katie Hobbs, who is now governor-elect.

The lawsuit alleges errors and inaccuracies at some voting centers and seeks to have Hamadeh installed as attorney general. A lawyer for Mayes says the suit is premature.
