Radio Smart Talk for Friday, January 28: In recent years, there have been calls, primarily from those preferring harder line immigration policies, for a repeal of the 14th Amendment to the U.S. Constitution. That's the Amendment which addresses U.S. citizenship. Passed and ratified in the aftermath of the Civil War, it was originally designed to address the citizenship status of former slaves and their families. It begins: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States." In other words, if you're born here, you're a citizen. We'll explore why some are seeking a repeal of the Amendment, and discuss similar efforts to do so in the past, with University of Baltimore Law Professor Garret Epps, and Dr. Steve Frank from the National Constitution Center. We'll also hear from Pennsylvania State Representative Daryl Metcalf, who supports repeal of the 14th Amendment.
