The U.S. Supreme Court heard arguments in Trump v. Barbara, a case challenging President Trump’s executive order to end birthright citizenship for children born in the U.S. to undocumented immigrants, focusing on the interpretation of the 14th Amendment’s Citizenship Clause. Justices expressed skepticism about the administration’s narrow reading of “subject to the jurisdiction thereof,” with several questioning the practicality and historical basis of excluding children of undocumented parents from citizenship. The Court’s forthcoming decision could significantly impact immigration policy and constitutional rights, with indications that a majority may uphold the longstanding broad protections of birthright citizenship.
