President Trump on Thursday renewed one of his longest-running political and legal fights, signing two executive actions aimed at restricting birthright citizenship despite a recent Supreme Court decision affirming the constitutional guarantee for most children born on American soil.

One order seeks to narrow automatic citizenship for some future births, while the other targets what the administration calls “birth tourism,” the practice of traveling to the United States to give birth so a child acquires American citizenship. The move immediately set up a new confrontation with civil-liberties groups and constitutional scholars, who said the president was again testing limits that the courts have already marked out.

The new citizenship directive is narrower than the sweeping order Mr. Trump issued at the start of his second term on Jan. 20, 2025. According to reporting on the measure, it focuses on more specific categories, including children born to certain foreign diplomatic or official personnel, people the government classifies as “alien enemies,” and cases involving alleged fraud in the acquisition of citizenship.

Even so, the legal and political stakes are high. The Supreme Court ruled only five weeks ago, on June 30, in *Trump v. Barbara*, that children born in the United States to parents who are unlawfully present or temporarily in the country are citizens at birth under the Fourteenth Amendment. That decision appeared to close off the broadest version of Mr. Trump’s effort. Thursday’s orders suggest his administration is now searching for narrower openings.

A Constitutional Fight Reopened

Birthright citizenship is rooted in the Citizenship Clause of the Fourteenth Amendment, which declares that all persons born or naturalized in the United States, and subject to its jurisdiction, are citizens. The principle was cemented in the 1898 Supreme Court case *United States v. Wong Kim Ark*, which held that a child born in the United States to noncitizen parents was a citizen so long as the parents were not serving in a diplomatic capacity.

That diplomatic exception has long been accepted. Children of accredited foreign diplomats are generally not considered subject to the full jurisdiction of the United States and therefore fall outside the ordinary rule of automatic citizenship. To that extent, parts of Mr. Trump’s new order may rest on already recognized doctrine.

But legal experts say other portions are far more uncertain. The order’s apparent attempt to reach children connected to “alien enemies,” or to cases involving fraud, raises questions about whether the executive branch can create new exceptions to a constitutional rule through administrative action. Civil-liberties advocates argued on Thursday that it cannot.

The American Civil Liberties Union condemned the new actions and said they were unlikely to survive judicial review, reflecting a broader view among immigration lawyers that the administration is trying to repackage a constitutional challenge it has already lost.

A Long Campaign

Mr. Trump’s latest action is not an isolated policy move but the continuation of an effort he has pursued for more than a decade. He has long argued that birthright citizenship encourages illegal immigration and creates incentives for foreign nationals to come to the United States to give birth. During campaigns and in office, he has repeatedly portrayed the constitutional guarantee as overly broad and vulnerable to reinterpretation by the executive branch.

That argument has found favor with some immigration restrictionists, but it has consistently run into the text of the Constitution and deep-rooted precedent. The Supreme Court’s June ruling was the clearest modern rebuke yet to the central premise of Mr. Trump’s broader campaign.

Since then, the administration has intensified its focus on “birth tourism,” especially where officials suspect visa fraud or misrepresentation. Going after fraud in the visa process is more conventionally within executive authority than redefining who is a citizen at birth. That distinction may help explain why the White House paired a narrower citizenship order with a separate action targeting travel for childbirth.

Still, critics said the dual orders appeared designed not just to address fraud but to keep alive a political issue that has animated Mr. Trump’s immigration agenda and energized his base.

What Comes Next

The central question now is whether any piece of the new orders can withstand court scrutiny. Some elements may largely restate existing law. Others could quickly be challenged as an attempt to do indirectly what the Supreme Court has said cannot be done directly.

Much may depend on implementation. If federal agencies move aggressively to deny documents or recognition to children born in the United States under the new categories, lawsuits could follow almost immediately. Courts would then have to determine whether the administration is merely enforcing narrow, established exceptions or trying to invent new ones.

The timing underscores the unusual posture of the dispute. Rather than backing away after the June decision, Mr. Trump has returned to the issue almost at once, signaling that the White House still sees legal, political or symbolic value in pressing the fight.

For now, the orders reopen a constitutional battle that seemed, at least in broad outline, to have been settled. And they test whether a president who has repeatedly sought to narrow one of the country’s oldest guarantees of citizenship can find even a small foothold where the courts have denied him a larger one.
