Trump Makes History Attending Supreme Court Arguments on Birthright Citizenship

President Donald Trump attended oral arguments at the U.S. Supreme Court on Wednesday, April 1, 2026, becoming the first sitting president in American history to do so, as the court considered the legality of his executive order seeking to restrict birthright citizenship. Trump signed the order on his first day back in office in January 2025, directing federal agencies not to recognize the citizenship of children born in the United States if neither parent is a citizen or legal permanent resident. The case, Trump v. Barbara, has already been blocked by multiple lower courts, including a federal court in New Hampshire, and has not taken effect anywhere in the country. Outside the neoclassical courthouse on Capitol Hill, demonstrators gathered holding anti-Trump signs ahead of the arguments. According to Reuters, Trump's motorcade drove from the White House along Constitution Avenue and Independence Avenue, passing the Washington Monument and the National Mall, with crowds watching from the sidewalk.

Justices across ideological lines press Sauer hard During more than two hours of arguments, a majority of justices appeared skeptical of the administration's legal position, presented by Solicitor General D. John Sauer. The administration argued that the phrase "subject to the jurisdiction thereof" in the 14th Amendment's Citizenship Clause refers to political allegiance or lawful residence, not mere physical presence on U.S. soil. Chief Justice John Roberts questioned the administration's authority to exclude children of undocumented immigrants from citizenship, saying, according to BBC, "I'm not quite sure how you can get to that big group." Roberts also described the historical examples Sauer cited in support of his argument as "very quirky," according to Axios. Justice Neil Gorsuch, one of three justices Trump appointed during his first term, pointed out that the concept of an "illegal alien" did not exist when the 14th Amendment was adopted in 1868, making it legally impossible for the amendment to have intended to exclude such a category of people. Justice Elena Kagan said Sauer was "looking for some more technical, esoteric meaning" in the citizenship clause, according to The Guardian. Cecillia Wang, a lawyer for the American Civil Liberties Union, which brought the legal challenge, argued in response that "practically everyone born on American soil is subject to its jurisdiction and is a citizen," excluding only those covered by the fiction of extraterritoriality, such as children of foreign diplomats.

Trump left the courtroom after Sauer finished his arguments According to Bloomberg, Trump stood up and left the courtroom after Sauer concluded his portion of the oral argument, before the full session ended. The conservative justices also questioned Wang, raising the prospect that the final ruling could be legally complicated with far-reaching implications regardless of the overall outcome, The Guardian reported. Roberts acknowledged at one point that "it's a new world," but added, according to Axios, "It's the same Constitution." The administration separately argued that the executive order was necessary to protect against modern national security threats and to curb "birth tourism," a practice it described as foreigners traveling to the United States specifically to secure citizenship for their children. Trump had previewed his combative posture toward the court on Sunday, posting on Truth Social that birthright citizenship "is not about rich people from China and the rest of the World who want their children and hundreds of thousands of others, FOR A FEE, to absurdly become citizens," according to AP News.

The 14th Amendment was ratified in 1868 primarily to guarantee citizenship to Black Americans, including formerly enslaved people, following the Civil War. The Supreme Court affirmed the broad scope of birthright citizenship in its 1898 ruling in United States v. Wong Kim Ark, a landmark case involving a man born in San Francisco to Chinese immigrant parents who were not U.S. citizens. That ruling has served as the legal foundation for birthright citizenship for over a century. Federal law has codified birthright citizenship rights since 1940. The current case marks the first time the Supreme Court has been asked to issue a final ruling on the constitutionality of an executive attempt to restrict birthright citizenship.

Second major court test for Trump after tariffs defeat The birthright citizenship case represents the second major constitutional challenge to Trump's agenda to reach the Supreme Court for a final ruling, following the court's February 20, 2026 decision that struck down his sweeping global tariffs in a 6-3 vote. Trump reacted furiously to that tariffs ruling, calling justices Gorsuch and Barrett "an embarrassment to their families" on the day it was issued, and later saying they "sicken me," according to Reuters. The court's 6-3 conservative majority includes three justices Trump appointed during his first term: Gorsuch in 2017, Brett Kavanaugh in 2018, and Amy Coney Barrett in 2020. In the tariffs case, Roberts, Gorsuch, and Barrett joined the court's three liberal members in ruling against the administration. A final ruling in the birthright citizenship case is expected in June 2026. Todd Schulte, president of the immigration advocacy group FWD.us, told Axios that the arguments advanced by the Trump administration "have been around for a long time and have never, ever, ever gotten traction," adding that since taking office, "not a single judge has ruled their way in any of the birthright citizenship cases, not one."
