House Natural Resources Committee Chairman Rob Bishop, R-Utah, plans to retire from Capitol Hill after his next term ends, presuming he can pull off a victory in next year's election race.

"When that is done, I am done," he said at a Friday town hall meeting in his state, according to the Standard-Examiner.

Bishop is an eight-term member of the House of Representatives, who has served two of his terms as chairman of the Natural Resources Committee, which holds sway over public lands policy and the Interior Department.

Under House rules, he is allowed to serve one more two-year term as chairman of the powerful committee. So, that's his plan: Win in 2018, serve as chairman for two more years, and retire in 2020.

His office on Monday confirmed the chairman's plan, saying it's true that he does not plan to run for reelection in 2020.

Bishop had discussed retirement earlier this Congress, his office pointed out.

"I can be chairman for 6 years. I have one more term after this … that I can be chairman, but I've told people that's going to be it," he said from a transcript of an interview earlier this year provided by his office. The interview was conducted by Chris Solomon for Outside Magazine.

Bishop faces opposition in the upcoming 2018 race from Republican Cathy Callow-Heusser and the Green Party's Adam Davis. But he is strongly favored in his home district and considered hard to beat.
