The Republican National Committee is slated to vote Friday on a resolution to censure GOP Reps. Liz Cheney of Wyoming and Adam Kinzinger of Illinois, according to reports.
Reports indicate that the RNC's resolutions committee unanimously advanced the measure on Thursday.
The two lawmakers targeted by the resolution have both been vociferous critics of former President Donald Trump.
Last year, Cheney was ousted from her role as House Republican conference chair.
Cheney and Kinzinger are the only two Republicans serving on the House select committee investigating the Jan. 6 Capitol riot. They were also both numbered among the 10 House Republicans who voted in favor of impeaching then-President Trump last year in the wake of the Jan. 6 episode.
"The leaders of the Republican Party have made themselves willing hostages to a man who admits he tried to overturn a presidential election and suggests he would pardon Jan. 6 defendants, some of whom have been charged with seditious conspiracy," Cheney declared in a statement. "I'm a constitutional conservative and I do not recognize those in my party who have abandoned the Constitution to embrace Donald Trump. History will be their judge. I will never stop fighting for our constitutional republic. No matter what."
While Kinzinger is not seeking re-election, Cheney is pursuing another term in office and will face Trump-backed Harriet Hageman during the Republican primary.
