David Cay Johnston, Pulitzer Prize-winning author, 2016 book, "The Making of Donald Trump" and 1992 book, "Temples of Chance".
"Donald Trump presents himself as a modern Midas even when much of what he touches turns to dross." http://www.nytimes.com/2016/08/21/books/review/inside-the-list-david-cay-johnston
Asked, "what’s the main theme from your years of studying Donald Trump and his operations?', Johnston replied, Donald doesn’t know anything. And if you listen carefully to what he says, it becomes apparent."
"Trump was asked by Hugh Hewitt during one of the debates about the U.S. nuclear triad, which is the capacity of the U.S. to deliver a nuclear bomb from a submarine missile, a land-based missile or an airplane. Trump's answer indicated he had no idea. Well, it turned out Hugh Hewitt had asked the same question months earlier on his radio show, and Trump didn’t learn in between."
