A federal judge has temporarily blocked a new executive order issued by President Donald Trump that aimed to limit birthright citizenship. This type of citizenship grants automatic U.S. citizenship to anyone born in the country, regardless of their parents' immigration status. The Trump administration has been trying to narrow or eliminate birthright citizenship since he returned to the White House last year, following a previous attempt that was rejected by the Supreme Court in June. The new executive order, signed last month, sought to deny citizenship to children of certain groups, including "alien enemies," foreign government employees, and people involved in "birth tourism." Birth tourism refers to the practice of traveling to the United States for the purpose of giving birth, with the goal of granting the child automatic U.S. citizenship. The order also aimed to block citizenship for individuals whose parents are associated with terrorist organizations, a category the Trump administration has expanded to include drug cartels. On Wednesday, U.S. District Judge Deborah Boardman issued a temporary block on the enforcement of the executive order. She ruled that a group of people who sued the administration are likely to succeed in proving the order violates the 14th Amendment to the Constitution. This amendment guarantees citizenship to "all persons born or naturalized in the United States, and subject to the jurisdiction thereof." The judge referenced the Supreme Court's earlier ruling, which she called "the law of the land," and stated that the new executive order is likely unconstitutional. The Trump administration argued that the Supreme Court's ruling did not prevent them from creating exceptions to birthright citizenship, such as those for diplomats or "alien enemies." However, the plaintiffs, including several immigrants and the advocacy group CASA, countered that such exceptions have historically been narrow and that the new executive order goes beyond what the Constitution allows. They emphasized that the president cannot unilaterally change the Constitution and that the order poses a risk of denying citizenship to people based on false claims against their parents. Some of the plaintiffs also expressed concerns about being affected by the executive order simply by purchasing a plane ticket to travel to the United States.
