Rep. Adam Kinzinger of Illinois, one of the critics of former President Donald Trump in the House Republican Conference, announced Friday he won’t seek reelection next year.

His decision came just hours after the Illinois state legislature passed a new congressional map that drew Kinzinger into the same district with another GOP incumbent, Rep. Darin LaHood.

“There’s little to no desire to bridge our differences, and unity is no longer a word we use,” Kinzinger said. “It has also become increasingly obvious that in order to break the narrative, I cannot focus on both a reelection to Congress and a broader fight nationwide.”

Adam Kinzinger retirement underscores Trump victory

Kinzinger is among the GOP critics of Trump and one of two Republicans, along with Rep. Liz Cheney (R-Wyo.), sitting on the special House panel investigating the Jan. 6 protest.

Kinzinger is one of 10 House Republicans to vote to impeach the then-president in January. His announcement marks the second member of that group to say he will retire from Congress, joining Rep. Anthony Gonzalez of Ohio. Most of the remaining eight lawmakers are facing serious primary challenges.

Trump, in a statement after Kinzinger’s announcement, wrote “2 down, 8 to go!”

“It’s a huge win for Trump,” a Trumpworld operative said of Kinzinger’s retirement. “Of all the impeachment guys, the three most important races were Tony Gonzalez, Liz Cheney and Adam Kinzinger. And two of those three are already out.”

That pressure from Trump could increase even more on those who remain in office as others announce their departures, according to The Hill.

Conservatives reacts to Kinzinger decision.

Members of the House Freedom Caucus have held press conferences calling for GOP leader Kevin McCarthy to approve a conference resolution that would’ve effectively removed Kinzinger and Rep. Liz Cheney (R-Wyo.) from their committee assignments for taking their seats on the panel examining the Capitol protest.

“Sadly since coming to Congress in January, I’ve seen firsthand that Reps. Kinzinger and Cheney have done more to hurt the Republican conference than help them while working for Adam Schiff and Nancy Pelosi,” freshman Rep. Lauren Boebert (R-Colo.) said in late July during the push to have Kinzinger removed. “These members should not be allowed in our closed door private meetings…why is he able to be part of those conversations while he goes back and confers with the opposition?”

And Rep. Marjorie Taylor Greene (R-Ga.) in a statement called Kinzinger a “traitor to the Republican party” over his opposition to Trump.
