Vice President JD Vance criticizes a recent Supreme Court decision upholding birthright citizenship, calling it a “major mistake.” In remarks reported by Fox News and The Hill, Vance says the ruling is disappointing even though he indicates the administration respects the Court’s decision. He argues that the decision could contribute to increased “birth tourism” and illegal immigration by encouraging people to travel to the United States for the purpose of having children who would automatically receive citizenship. The two outlets present the same core message from Vance: he opposes the practical implications he associates with the Supreme Court’s interpretation of citizenship law and warns that the outcome may attract more people seeking citizenship through birth. Both sources describe his comments as a warning about potential changes in migration patterns following the ruling, while also emphasizing that he frames his criticism as separate from any refusal to follow the Court’s authority.
