PORTLAND, Ore. – Portland Mayor Ted Wheeler has officially launched the search for a new police chief.

The national search is expected to be completed by July.

“This national search gives our community the chance to address fundamental questions about the direction of policing in Portland. I am dedicated to receiving and acting upon input provided by the community throughout this process,” Mayor Wheeler said in a news release.

The mayor has asked current Police Chief Mike Marshman to apply for the job, despite a recent internal investigation into whether the chief asked a subordinate to sign him into a training he did not attend. Wheeler returned Marshman to duty in early April after a summary investigation report found that Marshman did not violate the police bureau’s policies.

“The Mayor has been clear that he would like Chief Marshman to apply and compete for the job,” said Wheeler’s spokesman, Michael Cox.

The Portland police union said the overwhelming majority of its members support Marshman as police chief and oppose the national search.

Marshman took on the role of Portland Police Chief in June 2016 after then-chief Larry O’Dea retired amid an investigation.

O’Dea shot his friend while on a hunting trip in April 2016, and reportedly misled investigators.

Marshman was appointed by former mayor Charlie Hales. During Wheeler’s campaign, he promised to conduct a national search for a police chief.

The average tenure of a police chief is about three years, according to the Portland Police Association.
