Story highlights Rep. Chaffetz leaving Congress on June 30

He is reportedly eying a position at Fox News

(CNN) The chairman of the House oversight and government reform committee, Jason Chaffetz, is leaving Congress on June 30, the Utah Republican announced Thursday.

"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 social media. "This week I sent a letter to Governor (Gary) Herbert indicating my intention to resign from Congress effective June 30, 2017."

Chaffetz said last month he was not running for reelection, and then later said he might not finish out his term. He's reportedly eying a position at Fox News after leaving the House.

Chaffetz is head of a committee that is the House's investigatory arm into the Executive Branch. He has started digging into President Donald Trump's firing of FBI Director James Comey and the former director's memo saying Trump asked him to drop the investigation into former national security adviser Michael Flynn.

This week, Chaffetz sent a letter from FBI Director Andrew McCabe seeking all FBI notes and information on Comey's communications with Trump, and he announced a hearing next week where he's invited Comey to testify.
