Illinois Republican Rep. Adam Kinzinger decries the "cancer within the Republican Party" just days after he declared he would not run for reelection.
Kinzinger was a target of President Donald Trump after he voted to impeach him following the January 6 insurrection. On Friday, Kinzinger posted a video to Twitter saying that he didn't plan to run for reelection. He cited toxic hyper-partisanship, and warned that America is now a "poisoned nation."
"You can...fight for the truth. "You can fight the cancer in Republican Party of lies and conspiracy of dishonesty," Kinzinger said to ABC News' George Stephanopoulos Sunday.
"You eventually realize that it's Liz Cheney and me that are telling truth, and that there are approximately 190 people in Republican Party who aren't going say a single word," Kinzinger said. "There is a Republican caucus leader who embraces Donald Trump with everything he has."
Kinzinger has recently established his own political action committee, the Country First PAC.
"There are many people who feel politically homeless. Many people feel that something needs to be done in politics. Kinzinger said that it was important to get involved and see where it goes. "We are failing the American people, the political system and especially the Republicans, right now."
Kinzinger is second among the ten Republicans that voted to impeach Trump and has declared they won't be seeking reelection. Ohio Rep. Anthony Gonzalez declared earlier this year that after facing a primary challenge by Max Miller, an ex-Trump aide, he would not seek reelection.
Kinzinger was critical of his peers Republicans' loyalty to Trump and was therefore drawn out from his House district in Illinois' redistricting process. His district was combined with another safe Republican District, so Kinzinger would have to run against a GOP incumbent.
North Carolina Representative Madison Cawthorn slammed Kinzinger Saturday and stated he supported Kinzinger's opponent Darin LaHood, a fellow Republican.
Cawthorn tweeted, "If you oppose the MAGA agenda, I will make it my mission to primary you & throw your out of Congress." "Little Adam could not stand up to the anger of his constituency & my endorsement for his opponent."
Kinzinger announced that he has "witnessed" how Congress is divided.
He said, "There is little or no desire to reconcile our differences. Unity is a word that we no longer use." "It has also become more obvious to me, that I cannot concentrate on both a reelection in Congress and a larger fight nationally to break the narrative."
Kinzinger said, "This isn’t the end of me political future. It’s the beginning."
Kinzinger is a member of the House Select Committee that investigated the January 6 insurrection. He also pursued evidence from Trump's top allies. Kinzinger reminded the public that he was "still in" for the next 14-months.
He stated that he was excited to continue the January 6 commission in order to tell people the truth because they deserve it.
