Some voters in Apache County, Arizona, were turned away before they could cast ballots on Election Day due to faulty machines, with voting issues “the worst we’ve ever seen,” Katherine Belzowski, assistant attorney general at the Navajo Nation Department of Justice, told CNN.

The faulty machines, which are printing only propositions and not the candidates on the ballots, are forcing poll workers to use express voting machines or EVMs, Belzowski said. Each polling location in the county has only one EVM, and the machines are prone to freezing.

It is unclear what is causing the technical difficulties, but officials say voting issues are not new to Apache County.

“This isn’t the first time Apache County has had voting issues on Election Day, but this is the worst we’ve ever seen it,” Belzowski said. The Navajo Nation Department of Justice is looking into potential legal action to “at the very least” keep polling locations open late Tuesday.

A Democratic poll watcher in the county told CNN the voting difficulties are a “disgrace.”
