Republican congressman Steve King says Trump's base would abandon him for immigration reform

King said the president's base would leave "almost immediately.”

King also said he didn't support the president's stance on paid family leave, espoused by Trump's daughter, Ivanka, and didn't applaud that portion of his speech.

Nonetheless, King gave the speech “a very high grade.”

“When I heard him say the investment in infrastructure...it gave me a measure of hope if there’s going to be some private capital invested in that,” King said.

Trump’s address was punctuated by an emotional moment where Carryn Owens -- the wife of Navy SEAL William "Ryan" Owens, who was killed in a raid in Yemen authorized by Trump in January -- received a standing ovation.

The president discussed why he considered the raid successful, lauded Ryan Owens and acknowledged his widow.

Some lawmakers said that Trump should have stuck to praising the fallen SEAL and left the success of the raid out, but King disagreed. “I think if you ask Carryn Owens in one year, or five years or ten, or two or three generations from now they will look back on last night with great pride in their family,” King said.

As for the Affordable Care Act, known as Obamacare, King said that a GOP plan that espoused refundable tax credits is not a viable replacement because it implies that every American is entitled to a health insurance policy.

“There should not be that entitlement. We need to make sure that we take care of people and we can’t let them not have care,” King said, but added that a gap in insurance coverage could be covered by programs like public clinics and market competition.
