Avondale’s City Council has appointed a new mayor following a decision by Marie Lopez Rogers to resign the post to run for Maricopa County Supervisor.

The council unanimously appointed Kenneth Weise to the post at a meeting Monday evening. Weise was first elected to the Council in 2006 and his term as mayor will expire in December 2016. He is a business manager at a Scottsdale firm.

Rogers resigned to seek the 5th District seat vacated last month by longtime Supervisor Mary Rose Wilcox. Wilcox resigned to seek retiring Rep. Ed Pastor’s seat.

Rogers will face two fellow Democrats in the August primary — former Phoenix Councilman Michael Johnson and state Sen. Steve Gallardo. Republican Mark Riddles will face the winner in November.
