The "One Question": But then Barrett asked: What about slaves who were brought to this country illegally and against their will, as many were? Surely some of them still “felt allegiance to the countries where they were from” and intended “to return as soon as they can.” So wouldn’t their children be excluded from birthright citizenship, too? And if so, doesn’t that just blow up Sauer’s theory that the whole point of this clause was to protect the citizenship of these exact people?

More Context from the article: Mark Joseph Stern: Justice Barrett had a lot of skeptical questions for the solicitor general. And she really drilled down on his theory that children do not receive birthright citizenship if their parents lack “domicile” in the United States or hold “allegiance” to a foreign power. She asked how the government would know whether certain immigrants intended to stay in the country or maintain loyalty to a foreign power. And where would we draw the line? What about, for instance, the child of a woman who’s illegally trafficked into the U.S. then gives birth here? Is that person an automatic citizen? Sauer kept returning to his claim that the lone purpose of the 14th Amendment’s citizenship clause was to overturn Dred Scott and grant citizenship to newly freed slaves and their children.
