Flake tweeted a picture of a check he sent to Penzone’s campaign for $100, writing in the memo line, “County over Party.”

Jones went on to win the race.

Arpaio, who was sheriff of Maricopa County from 1993 to 2016, announced in August he would run for his old seat in 2020.

"The last four years have proven to be a time of lost opportunities to continue the kind of tough policing this county needs," Arpaio said in a statement. "Once back in office, I will use my position to restore pride to our law enforcement ranks, not only here, in the fourth-largest county in America, but across the country."

Arpaio sparked nationwide criticism for housing some of the prisoners under his supervision in outdoor “tent cities” and using so-called chain gangs during his time as sheriff.

He was also convicted on criminal contempt of a federal court after he refused to follow an order that he cease detaining people based on their immigration status, though Trump pardoned him in 2017.
