Rep. Steve King, R-Iowa, responded Friday to Donald Trump's recently tempered immigration comments by arguing that no undocumented immigrants should be permitted to stay in the country during a Trump presidency.

"Those who are here illegally, those who cross the border illegally and committed a crime, they are criminals," King said during an appearance on CNN's "New Day."

"Any of them that worked in America, odds are they committed document fraud," he added.

King said he would not mind if authorities failed to identify some of those undocumented immigrants during any immigration crackdown.

"It doesn't trouble me if they live in the shadows and we don't find them," he said. "That's what they came here to do, is to live in the shadows."

The Trump supporter said the Republican nominee should "reinforce" his original position on immigration, which he said revolved around restoring order to the process.

"I don't think my position is hard line," King said. "I think it's prudent."
