How permissive should US immigration policy be? What attributes should we require of the immigrants the United States does admit? And how does immigration affect those already living in the US, both native and foreign born? Reihan Salam answers all these questions and more in his new book, “Melting Pot or Civil War? A Son of Immigrants Makes the Case Against Open Borders,” which he joined the show to discuss with me.

Reihan Salam is executive editor of National Review and a National Review Institute fellow. He’s also a contributing editor at The Atlantic and National Affairs, and is the coauthor with Ross Douthat of “Grand New Party: How Conservatives Can Win the Working Class and Save the American Dream.” You can follow him on Twitter @Reihan.
