The Supreme Court Just Painted a Welcome Sign on the Citizenship Loophole

The Supreme Court has now done what institutional conservatives so often do when the machinery starts growling. It took a liberal assumption, treated it like ancient constitutional granite, polished it with precedent, and handed it back to the country as though the debate had already been settled by Moses on Sinai.

The case is Trump v. Barbara. The question was simple enough for any ordinary person to understand, even if the lawyers spent nearly two hundred pages decorating it with Blackstone, Reconstruction history, and judicial throat-clearing:

Does the Constitution require automatic citizenship for children born in the United States to parents who are here illegally or only temporarily?

President Trump said no. His executive order, issued on January 20, 2025, declared that such children were not “subject to the jurisdiction” of the United States in the constitutional sense, and therefore did not automatically qualify for citizenship under the Fourteenth Amendment or the Immigration and Nationality Act.

But the nation’s High Court rejected him.

Chief Justice John Roberts wrote the Court’s main opinion. The liberal justices joined him, and so did…guess who…Amy Coney Barrett.

Brett Kavanaugh concurred in the judgment but dissented from the constitutional holding. Thomas dissented. Alito dissented. Gorsuch dissented. The Roberts-Barrett majority held that children born here to parents unlawfully or temporarily present are “subject to the jurisdiction” of the United States and are citizens at birth under the Fourteenth Amendment.

That is the meat of it. That is the thing everyone should understand before the fog machine starts pumping out phrases like “longstanding tradition,” “settled law,” and “constitutional consensus.”

The Fourteenth Amendment was ratified after the Civil War. Its citizenship clause states that all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens. Its immediate purpose was to undo the effects of Dred Scott and secure citizenship for freed slaves. That was the moral battlefield of the amendment in its historical context. Black Americans were denied citizenship after enslaving them, and the Fourteenth Amendment supplied a constitutional answer.

Then came United States v. Wong Kim Ark in 1898. The Court held that Wong Kim Ark, born in San Francisco to Chinese parents who were legally domiciled in the United States, was a citizen. That case has been treated for more than a century as the great monument of birthright citizenship.

But here is where the dispute sharpens. Wong’s parents were not border-jumpers, visa tourists, foreign students here for a semester, or people passing through long enough to give birth. They were domiciled in the United States, legally living their lives here.

Thomas’s dissent made that point with a sledgehammer, noting that the Wong Kim Ark opinion itself repeatedly described Wong’s parents as permanently domiciled here.

But Roberts brushed that aside and “Amy Coney Barrett” joined him. And the Court took the practice that has hardened over recent decades—automatic citizenship for almost everyone born on American soil—and gave it constitutional armor.

That is a major disaster.
