The Springfield Republican has served as president pro tempore since January 2013.
Prior to his election to the Ohio Senate, Widener served three terms in the Ohio House of Representatives.
“Over the next two years, I will continue my commitment to helping the private sector create good-paying jobs and making Ohio an excellent place to live, work and raise a family,” Widener stated in a news release.
The Republican Majority Caucus also retained other members of its leadership team, including Sen. Keith Faber of Celina as senate president; Sen. Tom Patton of Strongsville as majority floor leader and Sen. Larry Obhof of Medina as majority whip.
Widener and the rest of the Ohio Senate leadership team will assume their roles on Jan. 5, 2015.
