I preach that you want to get in, serve and get out. "I've always believed that", said Chaffetz, (R) Utah. He was confronted, though, with an unexpected challenge from Democratic newcomer Kathryn Allen who raised more than a half-million dollars in the first quarter alone after Chaffetz suggested lower-income people should invest in health insurance rather than iPhones.
In a message posted to his Facebook page, the Utah Republican thanked his constituents for electing him to office, calling it an "honour and a privilege that I have never taken for granted".
Chaffetz's staff in Washington, D.C., and in Utah did not immediately respond to requests for comment.
"There has been a lot of speculation about what that might look like", Cox said.
According to two senior House GOP aides, top Republican leaders were told that the House Oversight Chairman was considering not running for re-election in 2018, and thinking about returning home to Utah.
After the F.B.I. director, James B. Comey, announced in July that the bureau would recommend that Mrs. Clinton not be charged over her use of a private email account when she was secretary of state, Mr. Chaffetz led House Republicans in rejecting Mr. Comey's conclusion. In October, he announced on Twitter that the FBI had reopened its investigation into Clinton.
Chaffetz's decision is likely awful news for Allen and the Democrats, as the district is normally not a competitive opportunity.
He's often even stumbled over himself trying to make headlines: over the summer he endorsed Trump only to recant his endorsement in October after it became clear Trump could be a political liability.
But he refused to look into contacts that Trump's national security adviser, Michael Flynn, had with a Russian official amid suspicions that Moscow played a role in influencing the US elections. 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. When asked by reporters if he is considering a run for the Senate instead, Chaffetz indicated he was not leaving the House to go that route.
Meanwhile Chaffetz's campaign committee recently purchased Jason2028.com and JasonChaffetz2028.com. Whether that's an indication of future plans or simply a reflection of the fact that his campaign bought up a number of possible domain names to prevent others from grabbing them is unclear.
