The Supreme Court handed President Donald Trump a decisive defeat on June 30, striking down his executive order to limit birthright citizenship—a cornerstone of his hardline immigration agenda. The ruling, coming as the nation prepares to celebrate its 250th anniversary, underscores the enduring power of the 14th Amendment’s citizenship clause. In a 6-3 decision, the justices rejected Trump’s attempt to redefine who qualifies as an American at birth, calling his order a violation of constitutional guarantees that have stood for over a century.
The decision marks another major rebuke for Trump, who has faced similar setbacks from the court on his signature tariffs and other expansive executive actions since returning to the White House last year. Yet, in other immigration cases, including a recent ruling allowing him to end deportation protections for hundreds of thousands, the justices have backed his authority. This time, however, they drew a firm line, stating that Trump cannot unilaterally alter the meaning of birthright citizenship.
Trump’s order, signed on his first day back in office, directed federal agencies to deny citizenship to babies born in the U.S. unless at least one parent was a citizen or lawful permanent resident. The policy was immediately challenged by expectant parents, immigrant rights groups, and 22 state attorneys general, sparking a legal firestorm. A federal judge in New Hampshire later blocked the order, ruling it likely violated the 14th Amendment and federal law codifying those rights.
During oral arguments in April, Trump attended the proceedings—a first for a sitting president—arguing that the citizenship clause had been misinterpreted. He claimed it should not apply to children of non-citizen or non-permanent resident parents, warning of “anchor babies” and national security threats from “birth tourism.” Conservative justices, however, dismissed these policy concerns, with Chief Justice John Roberts noting, “It’s a new world. It’s the same Constitution.”
The American Civil Liberties Union, which represented the plaintiffs, hailed the decision as a victory for core American values. “Ask any American what our citizenship rule is and they’ll tell you, everyone born here is a citizen alike,” said Cecillia Wang, the ACLU’s national legal director, who herself is a citizen due to the 14th Amendment because her Taiwanese parents were on student visas when she was born.
Under Trump’s policy, an estimated 255,000 children born annually in the U.S.—about 6% of all births—would have been denied citizenship, according to the Migration Policy Institute. The case, Trump v. Barbara, featured plaintiffs like a Honduran woman seeking asylum, identified as “Barbara,” and a Taiwanese woman known as “Susan,” who has four children, three born before the order and one after. “My baby has the right to citizenship and a future in the United States,” Susan said in court filings.
The 14th Amendment, adopted after the Civil War to overturn the infamous Dred Scott decision, declares: “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.” The court’s ruling reaffirms that this guarantee extends to all, regardless of their parents’ immigration status.
