"Well, you obviously cannot do that. You cannot end birthright citizenship with an executive order," Ryan told Lexington, Ky., radio station WVLK. "We didn’t like it when Obama tried changing immigration laws via executive action, and obviously as conservatives, we believe in the Constitution."

Ryan, who is retiring at the end of his term, said an executive order would not adhere to the 14th Amendment, adding that he thinks there is a better way to address the country's "unchecked illegal immigration."

“I think the smarter, faster solution here is to crack down on illegal immigration and obliviously support doing that,” he said. "But I'm a believer in the Constitution, I believe in interpreting the Constitution as written, and that means you can't so something like this via executive order."

Ryan's comments follow hours after Trump said in a new interview with Axios that he plans to draft an executive order that would terminate birthright citizenship for children of noncitizens who are born in the United States.

Trump asserted that he does not believe he needs congressional approval to make the change, sparking bipartisan backlash.

“You can definitely do it with an act of Congress. But now they’re saying I can do it just with an executive order,” he said before stating incorrectly: "We're the only country in the world where a person comes in and has a baby, and the baby is essentially a citizen of the United States ... with all of those benefits."

The United States and Canada are two of the only developed countries in the West to have birthright citizenship. Most Central and South American nations also have birthright citizenship.

“The President does not have the power to erase parts of the Constitution, but he and the GOP Congress have spent two years trying to erase protections for people with pre-existing conditions," she said in a statement.

“Clearly, Republicans will do absolutely anything to divert attention away from their votes to take away Americans’ health care.”
