President Donald Trump reacted to Tuesday’s Supreme Court ruling striking down his executive order and ensuring all babies born in the United States are guaranteed American citizenship.

The commander in chief did not express panic, as he said on Truth Social: “The Supreme Court upheld Birthright Citizenship, which is too bad for our Country, but we can easily make it up in Congress through Legislation, with the support of the President, that has now been determined during this process.

“No long and unwieldy Constitutional Amendment is necessary!

“Congress should start TODAY to work on ending expensive and unfair to our Country, Birthright Citizenship. They will have my Complete and Total Support!”

U.S. Rep. Chip Roy, R-Texas, told the Daily Signal the “Supreme Court failed the American people.”

“The 14th Amendment to the U.S. Constitution in no way stands for the proposition of creating a dangerous cottage industry of traveling to our soil to manufacture United States citizenship,” Roy continued. “The Supreme Court today should have said so explicitly and ended this damaging exploitation of our laws.”

Roy is now urging Congress to “immediately do at least two things it should have done long ago,” which include “defin[ing] the phrase ‘subject to the jurisdiction thereof’ very specifically to make clear that citizenship is tied to the citizenship of the parent, not the soil,” and “completely restrict[ing] funding from DHS or any other agency or state that provides documentation and status to anyone not subject to the ‘jurisdiction thereof.'”

“In other words, Congress must act immediately and must not hide behind the fiction that it must amend the Constitution to fix this abuse of our laws,” Roy added. “To do otherwise would be an abject failure of the United States Congress.”

Supreme Court Justice Samuel Alito ripped into his colleagues who supported birthright citizenship in Tuesday’s ruling, saying: “This is one of the most important decisions in the history of the Court, and in my judgment, the court has made a serious mistake.”

He indicated the court’s majority ruling “preserves a powerful incentive to enter or remain in this country illegally.”

“If the Fourteenth Amendment required these results, the country would have to live with them or amend the Constitution. But the Fourteenth Amendment does not include the rule the court now imposes on the country,” Alito wrote. “In my judgment, the Court has made a mistake that will seriously affect the country’s future.”

Charles Marino, a former Department of Homeland Security adviser, told Harris Faulkner of Fox News: “The Supreme Court blew it when it comes to birthright citizenship.”

“The American people lost today, and the reason why they lost today is because our national security was ignored, the current threat landscape was ignored by the Supreme Court, and the burden to the American taxpayer was ignored, based on entitlements. We have no further to look than the Somali community in Minnesota where head of households included Somalis in the country illegally account for 87% of welfare.”

“This burden is going to be astronomical. It will continue to serve as an incentive for illegal immigration. And I predict we’re gonna see a spike in attempts at the southwest and northern borders based on this ruling alone.”
