This week we welcome our very first guest from the upper ranks of Trumpworld: Marc Short, President Donald Trump's former legislative affairs director and a current Miller Center senior fellow at the University of Virginia. Marc talks about his experience working in the Trump White House, the advice he would give Republicans and Democrats today caught in the border-wall and immigration standoff, what "the administration should have done from the start," and why he believes Trump's emergency declaration is now all but an inevitability.
