President Donald Trump said he would ask Congress to end birthright citizenship after the Supreme Court struck down his executive order on the policy in a 6-3 ruling, according to The Sun. Trump suggested the decision was a win for China in a series of posts on Truth Social after the opinion was announced. “I would like to congratulate President Xi, and the Great Country of China, on their massive Birthright Citizenship WIN!” Trump wrote. China has been accused of using the policy for so-called “birth tourism,” with nationals having children in American territories to secure citizenship for their kids, per the report. Trump also said lawmakers could restrict birthright citizenship without amending the Constitution. The Supreme Court’s decision, handed down Tuesday, upheld the long-standing interpretation of the 14th Amendment and blocked Trump’s executive order from taking effect. Supreme Court’s ruling involved separate 6-3 and 5-4 splits among the justices The executive order, signed by Trump on January 20, 2025, sought to deny automatic citizenship to children born in the US whose mothers were in the country illegally or temporarily, and whose fathers were neither citizens nor permanent residents, per reports. Lower courts blocked the order before it could take effect, which eventually sent the dispute to the Supreme Court. The order had previously prompted a coalition of states to sue Trump over the policy. Justice Brett Kavanaugh provided the sixth vote against Trump’s order but did not join the majority’s constitutional reasoning. Kavanaugh said the order instead conflicted with a federal citizenship law that uses wording similar to the 14th Amendment.

Roberts was joined by Justices Sonia Sotomayor, Elena Kagan, Amy Coney Barrett, and Ketanji Brown Jackson. He wrote that children born on American soil to such parents are “citizens at birth.” “Citizenship, then and now, was the right to have rights, to freely participate in our political community,” Roberts wrote. “We keep that promise today,” he added. Trump seized on Kavanaugh’s separate reasoning to demand that Congress pass legislation restricting the right. President Trump has called on Congress to end birthright citizenship after the Supreme Court upheld the constitutional right and struck down his executive order seeking to redefine who is American. https://t.co/GA5NfAeH7Y— The Washington Post (@washingtonpost) June 30, 2026 “The Supreme Court upheld Birthright Citizenship, which is too bad for our Country, but we can easily make it up in Congress through Legislation,” Trump wrote on Truth Social. “No long and unwieldy Constitutional Amendment is necessary!” he said. Trump urged lawmakers to “start TODAY” on ending what he described as “expensive and unfair to our Country” birthright citizenship, adding, “They will have my Complete and Total Support!” Any such legislation would likely face a fresh legal challenge, since five justices found that the Constitution itself protects citizenship for the children covered by Trump’s order. Under the long-standing interpretation of US law, almost every child born on American soil automatically becomes a citizen regardless of their parents’ immigration status. This principle is known as jus soli, or “right of the soil,” because citizenship is based on where a person is born. Trump has separately drawn attention for rewarding public figures, who align with his citizenship-related initiatives, which includes rewarding Nicki Minaj with a gold card after she voiced support for one of his economic proposals for children. Other countries rely instead on jus sanguinis, or “right of blood,” which bases a child’s citizenship on the nationality of their parents. The 14th Amendment, ratified in 1868 after the Civil War, states that people “born or naturalized in the United States, and subject to the jurisdiction thereof” are citizens. Congress later included the same principle in a federal citizenship law passed in 1940, per reports. The Supreme Court issued several major rulings Tuesday, weighing in on birthright citizenship, transgender athletes in girls' and women's sports and on campaign spending limits.

The conservative majority ruled 6-3 that the long-standing campaign finance restrictions violated the First Amendment. Kavanaugh wrote that the caps had restricted the ability of parties to advertise and campaign alongside their candidates, stating, “More speech is generally better than less speech.” Trump celebrated that decision on Truth Social as well. “The Supreme Court just took restrictions off political spending!” he wrote, adding, “A BIG WIN FOR REPUBLICANS and, more importantly, The First Amendment!” The same day, the court also upheld, in a 6-3 ruling, bans on transgender girls and women competing in female sports in West Virginia and Idaho, according to reports. The White House celebrated that decision on X, stating, “FROM NOW ON, WOMEN’S SPORTS WILL ONLY BE FOR WOMEN.”
