Republican Congressman Steve King says he has “an uneasy feeling” about Donald Trump’s “softening” immigration stance.

King told ABC News there is “not much” about Trump’s evolving comments about immigration that have “encouraged” him. King has been one of the most vocal opponents in congress of what King calls “amnesty” for people who entered the country illegally. King told ABC is it “okay to soften some things,” but King said it is “not okay to let people violate the law and be rewarded for it.”

King is calling on Trump to “reject real amnesty with clarity.”

King backed Ted Cruz in the Iowa Caucuses. King has said he will vote for Trump in November. But King told Radio Iowa earlier this month saying he’ll vote for Trump is not a “full-throated” endorsement.
