Greg Treat

In 2019, Treat authored a bill to create the Legislative Office of Fiscal Transparency, an entity to increase transparency and accountability in state government by providing the public and lawmakers independent, objective data on state spending and program performance. Treat also authored several landmark government accountability] measures that give the governor the ability to hire and fire the director of five of the largest state agencies. Treat authored Senate Bill 1848 in 2014, which required abortion providers to have admitting privileges at a hospital within 30 miles (48 km) of their practice. The law was struck down by the Oklahoma Supreme Court in 2016, with the court citing Whole Woman's Health v. Hellerstedt as a precedent.

Treat was first elected to his seat in a 2011 special election to replace Todd Lamb, who left his seat to become Oklahoma's lieutenant governor. He defeated four other candidates in the Republican primary and did not face a Democratic opponent. He was reelected in 2012 without opposition and defeated Democrat Judy Mullen Hopper in 2016 with 66.35% of the vote.
