Trump Seeks Supreme Court Rehearing on Birthright Citizenship After Narrow Ruling Upholds Longstanding Doctrine

President Donald Trump announced plans to petition the U.S. Supreme Court for a rehearing of Trump v. Barbara, the case in which the Court on June 30, 2026, struck down his executive order restricting birthright citizenship for children born to parents who are unlawfully or temporarily present in the United States. The 5-4 decision, authored by Chief Justice John Roberts, reaffirmed that the Fourteenth Amendment’s Citizenship Clause guarantees citizenship to nearly all persons born on U.S. soil, subject only to narrow historical exceptions.

During April 1, 2026, oral arguments, Justices Amy Coney Barrett and Brett Kavanaugh posed pointed questions probing the administration’s interpretation of “subject to the jurisdiction thereof,” including issues of domicile, intent, foundlings, and administrative feasibility. Barrett explored hypotheticals involving unknown parentage and exceptions, while Kavanaugh inquired about practical implementation at hospitals and state agencies. Though the Court ultimately rejected the order— with Barrett joining the majority and Kavanaugh concurring on statutory grounds—the exchanges highlighted ongoing interpretive tensions.

Trump described the ruling as “absolutely insane” and vowed an immediate request for rehearing, a long-shot move given the Court’s rarity in granting such petitions. The litigation stems from Executive Order 14160, signed January 20, 2025, which sought to limit automatic citizenship.

Mainstream coverage has emphasized the constitutional stakes and immigration implications, though detailed analysis of judicial signals during argument has appeared primarily in specialized legal reporting. No independent corroboration emerged for anecdotal claims regarding specific justices’ personal reactions to external advertisements.
