Author Dinesh D’Souza rejoins the Dom Giordano Program to discuss his new book United States of Socialism, which contains themes that seem ever evolving in today’s political landscape. D’Souza explains that even though the book has been published and released, there’s already updates he wants to make to the book. Also, D’Souza lays forth the history of the holiday of Juneteenth, after calls to make the day a federal holiday gain momentum. D’Souza uses the discussion as an opportunity to highlight policies of Abraham Lincoln, and explain the rocky history of Democratic support of the former Republican president.(Photo by Shannon Finney/Getty Images)
