President Trump signed two new executive orders Thursday in his second attempt to narrow birthright citizenship, roughly five weeks after the Supreme Court struck down his original day-one order in a 6-3 ruling that upheld the 14th Amendment's guarantee of citizenship for nearly all children born on U.S. soil. Children of foreign diplomats are already excluded from birthright citizenship under existing law; Thursday's order could expand how many people fall under that category. Amanda Frost, a University of Virginia immigration law professor, had argued during the original order's legal battle that "if birth tourism is a problem, the answer is to enforce that regulation," rather than reinterpreting the 14th Amendment more broadly. The Trump administration argues Thursday's narrower orders remain within long-standing exceptions to birthright citizenship the Supreme Court has previously recognized, such as the existing exclusion for children of foreign diplomats, rather than attempting to reinterpret the amendment's core guarantee as the original order did. Trump told reporters he believes the narrower restrictions announced Thursday would withstand constitutional scrutiny where his broader original order did not.
