> *“In the end, the Fourteenth Amendment guarantees citizenship to nearly all persons born in the United States, with exceptions far narrower than the Executive Order’s scope. The president cannot ignore, rewrite, or abandon that promise by executive order. The Supreme Court should affirm the judgment below and issue a judgment that respects the right of birthright citizenship that the Fourteenth Amendment guaranteed.”*

Berry will be present for today’s oral arguments and will be issuing a statement immediately following the hearing. To speak with Berry further on today’s birthright citizenship oral arguments, contact [Christopher Tarvardian](mailto:ctarvardian@cato.org).
