Republican lawmakers want a constitutional amendment to end birthright citizenship after the Supreme Court ruled Tuesday that the children of aliens in the country temporarily or illegally are citizens of the U.S. if they were born in the country.

The Supreme Court decision addressed the meaning of the 14th Amendment's requirement that someone be born in the United States and "subject to the jurisdiction thereof," to secure birthright citizenship. The nature of the ruling effectively blocks the legislature from changing the policy without a constitutional amendment.

Sen. Mike Lee, R-Utah, posted after the ruling that "we're going to need a constitutional amendment." Sen. Rand Paul, R-Ky., for his part, responded to Lee and highlighted that he had already introduced a constitutional amendment to that effect earlier this year.

"Good thing I already filed one earlier this year," he posted, along with a link to the bill text.

Under Paul's amendment, a child born in the U.S. would need at least one parent who is either a U.S. citizen, a legal permanent resident, or an alien in the U.S. Armed Forces, to become a citizen.
