And the report of Chaffetz's sooner-than-expected departure from Congress comes at a time when he just got his powerful oversight panel a piece of the investigatory action around the growing scandals coming out of the White House.
On Tuesday, he vowed to get the memos Comey reportedly wrote about his meeting with Trump in which the president allegedly asked him to shut down the FBI investigation into ousted National Security Adviser Michael Flynn.
The congressman had been harshly criticized by constituents for what they saw as his inadequate response to allegations surrounding Trump.
Chaffetz would not discuss his next career move, which some have speculated might include a cable news gig, but he said he planned to keep his residence in Utah.
Chaffetz' chances to run again could be jeopardized by leaving office early, according to BYU political science professor Earl Fry.
"I expect he would represent a kind of expertise on Congress and might represent a somewhat pro-Trump viewpoint", Pope said in an email.
The five-term congressman rescinded his endorsement of Trump previous year after recordings surfaced of the reality show star bragging about groping women, only to hastily re-endorse Trump shortly before the FBI announced it was reviving its investigation into Clinton's emails. "I'm not the only one who can do this job".

But in a ideal world, he'd be single and there would be a third Middleton sister for him to marry. Both had important roles in the ceremony, as George was a page boy and Charlotte a bridesmaid.
Pope said though Chaffetz has hinted at re-election in a few years, he probably won't be re-elected to his seat.
Chaffetz said in a statement published Thursday that he made a decision to resign to spend more time with his family.
The announcement by Chaffetz, 50, was the latest upending of the Republican-controlled congressional investigations into Trump. "I've been disappointed in the Trump administration because they have not loosened up the documents in the State Department and Justice Department".
Chaffetz's committee has a hearing set for next Wednesday, and he said he would like Comey to testify.
"There are lots of good people who care about these issues and are well-suited to carry out these investigations", Chaffetz said.
Utah's election law says that if a U.S. House seat becomes vacant, the governor will call a special election.
Cox's chief deputy, Mark Thomas, said that election officials do not yet know what the special election will cost the state, but he said some money will be saved because the primary and general election dates fall on the same days that municipal elections are being held.
