TULSA — Oklahoma state Sen. Dan Newberry has announced he will resign his seat to pursue a private-sector promotion.

In a Facebook post, the third-term business-friendly senator said he will remain in senior management at TTCU The Credit Union and plugged his forthcoming book, titled "The Rich Young Ruler."

The Tulsa Republican thanked his supporters for his more than nine years of elected office.

Newberry won re-election in November after two hotly contested races. He won the primary vote with more than 69 percent but more narrowly edged former Sand Springs Superintendent Lloyd Snow, a Democrat, with almost 56 percent of the vote in the general election.
