Supreme Court Confronts Trump's Attack on Birthright Citizenship -- and the Specter of Mass Denaturalization

The Question Before the Court

The Trump administration wants the Supreme Court to rule that babies born in the United States to undocumented or temporary residents are not automatically citizens -- upending 150 years of constitutional interpretation and the plain text of the 14th Amendment.

The executive order, signed on Trump's first day back in office, calls citizenship a "privilege" and a "priceless and profound gift" -- not a constitutional right guaranteed to nearly everyone born on American soil.

During oral arguments last week, Justice Sonia Sotomayor cut to the heart of what's at stake: If the court accepts the administration's reasoning, what stops this president or the next from stripping citizenship from people already born here?

"There would be nothing limiting that, according to your theory," Sotomayor told Solicitor General D. John Sauer.

The Administration's Argument -- and Its History

The Trump administration claims the 14th Amendment's phrase "subject to the jurisdiction thereof" excludes children of undocumented immigrants. Most historians and legal scholars reject this reading outright.

Trump himself has framed birthright citizenship as a Reconstruction-era provision meant only for formerly enslaved people. "The reason was it had to do with the babies of slaves," he told reporters in the Oval Office.

That's not what the amendment says. It says "all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens." The Supreme Court affirmed this in 1898 in United States v. Wong Kim Ark, ruling that a man born in San Francisco to Chinese immigrant parents was a citizen -- even after immigration officials tried to bar him from re-entering the country.

Norman Wong, a grandchild of Wong Kim Ark, stood outside the Supreme Court last week to remind justices of that history. "Birthright citizenship is not just a legal principle," he said. "It's a statement about who we are as a nation."

The Threat of Denaturalization

Sotomayor pressed Sauer on United States v. Thind, a 1923 Supreme Court case that ruled a Sikh man from India wasn't eligible for citizenship because he didn't qualify as a "free white person" under federal law at the time. After that decision, the government revoked the citizenship of dozens of South Asian Americans.

Could the logic of Trump's executive order permit the same thing today -- stripping citizenship from people born here to undocumented parents?

Sauer insisted the administration was only seeking "prospective relief" and wouldn't pursue retroactive denaturalization. But Sotomayor wasn't buying it. "Yeah, that's what you're asking for relief right now," she said. "I'm asking whether the logic of your theory would permit" mass denaturalization.

The Fred T. Korematsu Center for Law and Equality, along with more than 70 other civil rights organizations, filed a brief warning exactly that: If the court strips away birthright citizenship, it opens the door to revoking the citizenship of countless Americans based on their parents' immigration status.

Who Counts as American?

The case has prompted a broader debate about national identity -- one that some Republicans have embraced explicitly.

At a conference on "national conservatism" last fall, Senator Eric Schmitt of Missouri described America as "a way of life that is ours, and only ours, and if we disappear, then America, too, will cease to exist." Schmitt filed a brief supporting Trump's order, arguing that citizenship should apply only to those "allowed to adopt our country as their permanent and lawful home."

This vision of America -- bound by cultural heritage and bloodlines rather than shared principles -- stands in sharp contrast to the 14th Amendment's promise that anyone born here, regardless of parentage, is an American.

What Happens Next

A majority of the court, including several conservative justices, appeared skeptical of the administration's argument during oral arguments. The order has never taken effect, blocked by lower courts since it was signed.

But even if the Supreme Court strikes it down, the case has already done damage. It has legitimized the idea that citizenship is a revocable privilege, not a constitutional guarantee. It has put millions of Americans -- born here, raised here, living here -- on notice that their status could be questioned based on who their parents are.

And it has forced the country to confront a question that should have been settled in 1868: Are we a nation where all people born here are equal under the law, or are we something else?

The court will issue its decision later this year. Whatever the outcome, the Trump administration has made clear that it views citizenship as something to be granted or withheld -- not as an inalienable right.
