The Supreme Courtroom witnessed an unusual scene today: former President Donald Trump, in a move described as unprecedented for a sitting or former president, observed oral arguments in a case directly challenging his administration’s attempt to dismantle birthright citizenship. The arguments centered on Trump v. Barbara, a case brought by the ACLU and other civil rights groups contesting a 2025 executive order seeking to deny citizenship to U.S.-born children of non-citizens and non-permanent residents. Reports indicate Trump departed shortly after the questioning of Cecillia Wang, the ACLU’s lead counsel, began.
A Familiar Fight, A Troubling Precedent
The case itself isn’t entirely new territory. As legal observers noted, the Trump administration’s attempt to redefine the Fourteenth Amendment – which guarantees citizenship to “all persons born or naturalized in the United States” – flies in the face of over 150 years of legal precedent, including the landmark 1898 United States v. Wong Kim Ark ruling. That decision definitively established birthright citizenship for children born in the U.S. To parents who are not citizens. Yet, the fact that the Supreme Court even agreed to hear the case, and the arguments presented by the administration, raised concerns about the potential erosion of established constitutional rights.
The administration’s argument, as presented by Solicitor General John Sauer, reportedly focused on a narrow interpretation of the Fourteenth Amendment, suggesting it was primarily intended to address the citizenship rights of formerly enslaved people. This line of reasoning drew sharp criticism from several justices, including Chief Justice John Roberts, who described it as “quirky” and “idiosyncratic,” and Justice Neil Gorsuch, who questioned the reliance on obscure historical sources. Justice Amy Coney Barrett directly challenged Sauer, asking pointedly, “What about the Constitution?”
A Court Skeptical of the Administration’s Case
The justices’ skepticism extended beyond the conservative wing of the court. The three liberal justices also voiced strong doubts about the administration’s legal arguments. Only Justices Samuel Alito and Clarence Thomas appeared potentially open to siding with the government. Sauer’s decision not to explicitly ask the Court to overturn Wong Kim Ark was described by ACLU’s Cecillia Wang as a “fatal concession.” Justice Brett Kavanaugh even suggested the Court could issue a brief opinion reaffirming the existing precedent.
The ACLU, representing a nationwide class of children potentially affected by the executive order, argued that the administration’s attempt to redefine birthright citizenship was not only legally unsound but also fundamentally at odds with American values. Cecillia Wang, herself the daughter of immigrants, presented a compelling case rooted in the clear language of the Fourteenth Amendment and decades of established legal precedent.
While a final decision is expected by the end of June or early July, today’s proceedings suggest the Supreme Court is unlikely to uphold the Trump administration’s attempt to alter the fundamental understanding of who is considered an American citizen. However, the fact that the case reached this stage remains a stark reminder of the fragility of established rights and the potential for political agendas to challenge constitutional principles.
Given the justices’ apparent disinclination to revisit established precedent, what lasting impact will this case have on the broader debate surrounding immigration and citizenship in the United States?
