Tennessee Lt. Gov. Randy McNally won't seek reelection

What he's saying: "We have maintained balanced budgets, built one of the largest rainy day funds in state history, cut taxes to spur economic growth, and made strategic investments in education and workforce development," McNally said. "At the same time, we have strengthened public safety, kept our debt low, and ensured responsible spending."

Flashback: McNally, from Oak Ridge, is just the second Republican to serve as speaker of the Senate in modern Tennessee history. He was chosen by his colleagues to lead the Senate in 2017.

• Prior to that, he chaired the Senate finance, ways and means committee for a decade.
• McNally was first elected to the House in 1978 and then to the Senate in 1986.

The intrigue: McNally worked undercover in the late 1980s to assist federal and state investigators in the Operation Rocky Top corruption scandal.

What's next: With McNally's departure, the Republican super-majority will choose a new lieutenant governor in January.
