"I'm not going to be here forever", Chaffetz said of Washington.
In reality, a Democrat in his district, Kathryn Allen, had already raised $400,000 to go up against Chaffetz next November, accordingto the New York Times, while a primary challenger, Damian W. Kidd, also planned to go up against the congressman.
Chaffetz has represented Utah in the House of Representatives since 2009, after he defeated incumbent Rep. Chris Cannon for the GOP nomination. Chaffetz said on his Facebook page that he had consulted with his family and decided that he would not be a candidate for any office in 2018 and would return to the private sector when his term ends in January of 2019.

"This is a signal that anyone who's cozying up and enabling Donald Trump and his extreme agenda is feeling incredible pressure, and Rep. Chaffetz didn't like that pressure", he said. "Vote him out", the crowd chanted.
Instead, as much as perhaps any member of Congress, his fortunes turned considerably with Mr. Trump's victory.
In addition, Chaffetz has made a series of high-profile gaffes in recent weeks, including a freakish tirade in March in which he said iPhones were keeping poor people from affording health care. Chaffetz repeatedly said, "hold on", and "give me a second", as audience members in a Salt Lake City suburb reacted negatively to almost all of his statements and implored him to "do your job" and investigate Trump.
Five days after the announcement, Mr. Chaffetz asked the Justice Department to investigate whether Mrs. Clinton had lied in her testimony before Congress about the 2012 attacks in Benghazi, Libya. Representative Jason Chaffetz, chairman of the House Oversight and Government Reform Committee, told supporters he will not run for any office in the upcoming election. Trump dashed Chaffetz's plans to become a household name. This was hammered at home for Chaffetz in February at a town hall meeting where he was booed and told "do your job" after saying his committee would not investigate Trump's former national security adviser, Michael Flynn.
Other controversies had nothing to do with oversight. Last election, he walloped his Democratic challenger Stephen Tryon by garnering 73 percent of the vote and beat his primary opponent with almost 79 percent.
House Speaker Paul Ryan tweeted that Chaffetz is "a great defender of liberty and limited government" and wished him the best.
If Chaffetz runs for governor, he won't necessarily be the front-runner, Karpowitz said.
