Rep. Jason Chaffetz, R-Utah, announced on Thursday that he will leave Congress on June 30, according to the Deseret News.

"As you know, after careful consideration and long discussion with my wife, Julie, we agree the time has come for us to move on from this part of our life," Chaffetz wrote in a letter posted on his website.

The five-term congressman said he sent a letter this week to Gov. Gary Herbert indicating his intention to resign effective June 30. The governor's office said it received the letter Thursday.

Herbert will likely call a special election replace him as the representative for 3rd congressional district, the Deseret News reported.

But who will replace Chaffetz as chairman for the House of Oversight Committee?

According to The Hill, Rep. Trey Gowdy, R-S.C., will take the spot.

Gowdy, the former Benghazi Committee chairman, emerged as a front-runner to replace Chaffetz in the position, sources told The Hill.

Gowdy has collected endorsements from colleagues this entire week, hoping it’ll help him in his pursuit to be the next chairman, The Hill reported.

Chaffetz considers Gowdy his “best friend,” according to the Deseret News.
