Jason Chaffetz, American politician
Jason E. Chaffetz (; born March 26, 1967) is an American retired politician who served as the U.S. representative for Utah's 3rd congressional district from 2009 until his retirement in 2017. He chaired the Committee on Oversight and Government Reform from 2015 until 2017.

Chaffetz came to prominence in 2015 for his extensive investigations into Hillary Clinton. He rescinded his endorsement of Donald Trump in early October 2016 but expressed his intent to vote for him three weeks later. Having investigated Clinton and the Obama administration extensively, Chaffetz drew criticism after the 2016 election for declining to investigate certain potential conflicts of interest relating to President Donald J. Trump, and that of other individuals involved in his 2016 presidential campaign and subsequent presidential administration.

He resigned from office in 2017, six months into his fifth Congressional term, and has since been a commentator, Fox News contributor, and author.
