The text of Rush's censure resolution lists more than a dozen examples of King's remarks, beginning with comments in 2006 in which he compared immigrants to livestock and ending with his lamentation in the New York Times last week that white supremacy and white nationalism have become offensive terms.
McCarthy, R-Calif., called King's remarks "beneath the dignity of the Party of Lincoln and the United States of America".
"Republicans, in the interest of political expediency, sought his endorsement, ignored his racist remarks, and continued to elevate him to positions of influence", Rush said in a longer statement.
Censure is one of three formal modes of punishment in the House. Rep. James Clyburn, D-S.C., the party's No. 3 leader, said Monday he would introduce a resolution to express "disapproval of Mr. King's comments and condemnation of white nationalism and white supremacy in all forms".
"There is no place in the Republican Party, the Congress or the country for an ideology of racial supremacy of any kind", he said.

"I will admit I am unsure who is offended by the term "Western civilization" on its own, but anyone who needs "white nationalist" or "white supremacist" defined, described and defended does lack some pretty common knowledge", Scott wrote.
"Ultimately, I told him 'You have to do what you have to do and I will do what I have to do.' I will continue to point out the truth and work with all the vigor that I have to represent 4th District Iowans for at least the next two years".
The decision to remove King from the committees came amid a wave of backlash in Congress for his comments.
"Rep King's statements are unwelcome and unworthy of his elected position". "Today I denounce the words of Representative Steve King and I do so invoking the words of another king, Dr. Martin Luther King Jr., who if would have been allowed to live, would be celebrating his 90th birthday tomorrow", said Clyburn, who is black. "The word racist, the word Nazi, the word fascist, the phrase white nationalists, the phrase white supremacists". It was offensive enough for Republicans in the House and Senate to reprimand him, or call for his resignation, despite weathering years of similar, slightly more subtle comments from the only Iowa GOP rep in the House.
"I think he ought to step aside, and I think Congress ought to make it very clear he has no place there", Romney said, per CNN. King advocated for building a wall on the southern USA border before Trump ran for office and made the wall a signature campaign promise.
