Per the Raleigh News & Observer:

U.S. Sen. Richard Burr won’t run for another term – or for any elected office – after this year’s election, he told North Carolina Republican convention delegates Wednesday.

Burr, the state’s senior Republican senator, is seeking his third term in this year’s election, facing a challenge from former N.C. Rep. Deborah Ross, a Democrat. If he wins in November, he said he’ll serve the six-year term and then retire from politics in 2022.

“It’s real simple: I’m beginning to get old,” Burr, 60, told reporters after the delegation’s breakfast at a suburban Cleveland hotel. “I still look forward to getting back into the private sector before retirement even comes into the picture. I never envisioned retiring out of the Congress.”
