PORTLAND, Ore. -- Oregon State Treasurer Ted Wheeler made it official Tuesday and filed the paperwork required to run for Portland mayor.

Wheeler, a Democrat, had already announced his plan to run for mayor. He said some of he biggest issues the intends to focus on include tackling the affordable housing crisis and helping the city's homeless. He also mentioned other priorities of maintaining roads and infrastructure, filling potholes and economic recovery.

"This city deserves a good, solid and robust debate on the issues facing this community," he told KGW Tuesday. "We need to align different potential mayoral candidates' vision for this city, hold them up to the light of day, let the public comment and may the best candidate win."

Wheeler said he plans to spend the next few months talking with people in the community about what they expect from Portland's next mayor. He added that he looks forward to pitting his ideas against other candidates.

So far, five other people have filed to run for mayor. They are Lew Humble, David Schor, Trevor Manning, David "The Ack" Ackerman and Steven Entwisle, Sr. Mayor Charlie Hales has said that he will not run.

Term limits prevented Wheeler from seeking another term as treasurer. Until February, he was considered likely to run for what would have been an open governor's race in 2018. The picture changed, however, when John Kitzhaber resigned as governor and was replaced by Kate Brown. Armed with the power of incumbency, Brown is expected to seek the Democratic nomination.More top stories:Portland ranked among 'Booziest Cities in America'Sweet Cakes by Melissa pays $135,000 fineWatch: Daring helicopter rescue at Ore.
