Next month, the Supreme Court will hear arguments in the birthright citizenship case, Trump v. Barbara. It’s still somewhat unbelievable that the high court will entertain arguments in favor of gutting an utterly clear constitutional commitment. Nonetheless, our motto on Amicus is “legal knowledge is power,” and in this case, historical understanding of legal knowledge … is power. On this week’s show, Dahlia Lithwick interviews constitutional and immigration scholar Anna O. Law about her forthcoming book, Migration and the Origins of American Citizenship.

In preparation for a lot of very bad originalist takes, Lithwick and Law discuss how immigration actually worked in the colonial and pre-Civil War eras and why the framers of the Reconstruction Amendments (including the birthright citizenship clause of the 14th Amendment) meant exactly what they said and said exactly what they meant. Law also explains how and why Wong Kim Ark affirmed birthright citizenship for children of Chinese immigrants, and emphasizes that the words “subject to the jurisdiction” had narrow historical exceptions. Finally, a reminder that the framers of the 14th Amendment chose to constitutionalize citizenship rather than establish it in statute—in anticipation of exactly the situation America finds itself in today.
