Updated 3:25 p.m. | Utah Rep. Jason Chaffetz on Thursday announced his plans to leave Congress before the end of his term. The move comes just when the Utah Republican has placed himself in the middle of the ongoing controversy over President Donald Trump’s firing of FBI Director James B. Comey.

In a letter to constituents, Chaffetz said he would leave Congress at the end of June.

“I told voters I did not believe Congress should be a lifetime career,” the congressman wrote. “I knew from day one that my service there would not last forever.”

The news, first reported by Politico, puts into motion a potentially uncertain special election process in Utah, where state lawmakers are in a stare-down with Gov. Gary Herbert over how to elect Chaffetz’s replacement. Republicans in the Utah legislature want Herbert to call a special session so they can pass a law codifying how such an election would proceed, the Deseret News reported. Lawmakers are concerned that the current special election process doesn’t provide adequate time for candidates to engage in the election.

Chaffetz, the chairman of the House Committee on Oversight and Government Reform, announced last month that he would leave Congress at the end of his term.
