How discovery of slave ship Clotilda informs U.S. history

The remains of the last slave ship that came to America have been found. In 1860, the schooner Clotilda brought 110 Africans to U.S. shores, decades after it was illegal to import slaves into the country. The wreckage of the boat was discovered in Alabama’s Mobile River. Megan Thompson reports on the search for Clotilda, its history and the significance for the descendants of those slaves.
