OKLAHOMA CITY (AP) — Oklahoma City Mayor Mick Cornett is the latest candidate to announce plans to seek the Republican nomination for Oklahoma governor in 2018.

The 58-year-old, four-term mayor of the state’s largest city announced late Wednesday on Twitter and Facebook that he will formally file his candidacy papers next week.

Cornett joins a crowded GOP field that includes State Auditor Gary Jones, Lt. Gov. Todd Lamb and Tulsa attorney Gary Richardson. Gov. Mary Fallin is term-limited and can’t run again.

Cornett played a key role in recruiting the NBA to Oklahoma City and helped spearhead the continuation of a sales tax initiative that has revitalized the downtown and Oklahoma River districts. He has spent the last year as the president of the U.S. Conference of Mayors.
