Pima County's treasurer, Brian Johnson, has resigned

“This was a very difficult decision, but recent urgent changes in my personal responsibilities have made it clear that I can no longer serve the citizens of Pima County at the level they deserve,” Johnson wrote in a letter to the five county supervisors Friday afternoon.

Johnson, a Democrat, won the 2024 treasurer’s race by about 42,000 votes over the former Republican Treasurer Chris Ackerley.

The Board of Supervisors is responsible for filling vacancies in elected county offices, and will appoint a Democrat to serve until the next regular general election in 2028, said Pima County spokesperson Mark Evans.

Day to day operations of the treasurer’s office are being overseen by Chief Deputy Treasurer Jake Martin, Evans said. It’s still undecided whether the Supervisors will discuss the new appointed treasurer at their next meeting on June 23.
