On January 20, 2025, his first day back in office, President Trump signed Executive Order 14160, titled "Protecting the Meaning and Value of American Citizenship." It directed federal agencies to stop recognizing citizenship for children born in the U.S. to parents who were either undocumented or held only temporary legal status (such as tourist or student visas), arguing these children were not "subject to the jurisdiction" of the United States within the meaning of the 14th Amendment's Citizenship Clause.
That clause reads: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside." Since the 14th Amendment's ratification in 1868, the Supreme Court had interpreted this to mean essentially every child born on U.S. soil is a citizen at birth, regardless of their parents' immigration status, a reading the executive order directly challenged.
On June 30, 2026, the Supreme Court issued its ruling in Trump v. Barbara, striking down the executive order by a 6-3 vote. Chief Justice Roberts, writing for the majority, traced the legal principle back through early English common law (where children born in Britain automatically became British subjects) and explained that the 14th Amendment was specifically adopted in 1868 to repudiate the Supreme Court's 1857 Dred Scott decision, which had denied citizenship to Black Americans.
Justice Samuel Alito wrote the dissent, calling the ruling "one of the most important decisions in the history of the Court" while arguing it was "a serious mistake," contending the 14th Amendment was intended to confer citizenship only on children who, at birth, "owe allegiance solely to this country." With the ruling issued, birthright citizenship as historically understood remains the binding constitutional standard nationwide.
Along the way, this case also produced a separate, consequential Supreme Court ruling on judicial procedure itself. On June 27, 2025, in Trump v. CASA, Inc., the Court ruled that individual federal district judges generally lack authority to issue nationwide injunctions blocking a policy for the entire country, only for the specific parties before that judge. This complicated the birthright citizenship litigation procedurally, since lower courts had initially blocked the executive order nationwide, and legal experts note the practical impact of that separate ruling remains somewhat uncertain even after the birthright citizenship case itself was resolved.
During oral arguments in April 2026, Justice Sonia Sotomayor raised a broader concern beyond the immediate case: that legal reasoning supporting the administration's reinterpretation of the 14th Amendment could theoretically be used by a future administration to pursue stripping citizenship from people already born in the U.S. to undocumented parents, not just prevent it going forward.
Birthright citizenship, legally termed jus soli ("right of the soil"), had been essentially settled constitutional law for over a century before this case, making the executive order's legal theory a genuinely novel challenge to century-old precedent rather than a dispute over an unsettled area of law. That's part of why this case drew such wide legal attention beyond the immigration policy community specifically: it tested whether an executive order could functionally reinterpret a constitutional amendment's meaning, a question with implications well beyond citizenship policy alone.
Supporters of the now-struck-down order generally argued birthright citizenship as broadly applied creates an incentive for unauthorized immigration specifically to secure citizenship for children, and that the 14th Amendment's original intent was narrower than its modern application. Opponents generally argued the constitutional text and 150+ years of settled precedent were clear, and that changing this fundamental citizenship rule should require a constitutional amendment through Congress and the states, not a unilateral executive order. With the Supreme Court's ruling now final, this specific legal question is resolved as a matter of constitutional law, though the underlying political debate over immigration policy more broadly continues.
