Utah Rep. Jason Chaffetz, the high-profile chairman of the House Oversight and Government Reform Committee, won't seek re-election in 2018.

"After long consultation with my family and prayerful consideration, I have decided I will not be a candidate for any office in 2018," Chaffetz said in a statement on Facebook.

Chaffetz's role as the leader of the House Oversight Committee put him in the spotlight as he led investigations into Hillary Clinton's private email server and many aspects of former President Barack Obama's administration.

Chaffetz has also drawn flack for not being as animated to investigate President Trump's business connections and how they might impact his presidency. In his statement, Chaffetz ruled out running for any political office in 2018. There have been rumblings about potential Republican challengers for Sen. Orrin Hatch's seat in the U.S. Senate. Hatch seems intent on running for re-election in 2018, but rumors have seen several high-profile names, such as Mitt Romney, floated for the seat.

However, Chaffetz didn't rule out returning to politics in the future.

"I have long advocated public service should be for a limited time and not a lifetime or full career. Many of you have heard me advocate, 'Get in, serve, and get out,'" Chaffetz said. "After more than 1,500 nights away from my home, it is time. I may run again for public office, but not in 2018."

It's unclear if that future could mean a run for governor of Utah. The next gubernatorial election in Utah is in 2020.

Chaffetz said there is nothing unsavory causing him to step down.

"For those that would speculate otherwise, let me be clear that I have no ulterior motives. I am healthy. I am confident I would continue to be re-elected by large margins," he said. "I have the full support of Speaker Ryan to continue as Chairman of the Oversight and Government Reform Committee. That said, I have made a personal decision to return to the private sector," he said.

Chaffetz said he's confident his seat will be won by a Republican in 2018.

National Republican Congressional Committee chairman Rep. Steve Stivers, R-Ohio, thanks Chaffetz for his service to the country and the conference.

"Jason Chaffetz has been a valuable member of the Republican team, and we wish him the best as he begins this new chapter in his life. I'm proud to call him a friend," Stivers said. "Republicans have a deep bench of talented candidates in Utah who are more than up to this challenge. The NRCC is very confident in our ability to keep this seat red in November 2018."
