Matthew Vadum of the Capital Research Center joins us to discuss his new book chronicling the radical history of ACORN – the community organizing group brought to its knees in 2009 by a series of undercover videos. So why is ACORN still a threat? What forms does it exist in now? And how much of a link between ACORN and President Obama still exists? We discuss it all in the first half of our discussion with Matthew Vadum, author of “Subversion Inc.”
