President Donald Trump issued an executive order that would end birthright citizenship as commonly understood. More than a year later, the Supreme Court is set to hear arguments on the case, and Professors Jason Mazzone and Vikram Amar believe the order should be invalidated. Writing at Justia Verdict, the professors argue, again, that the order violates the first sentence of Section One of the Fourteenth Amendment, and it also flouts the 1952 Immigration and Nationality Act.
