Dave Ross talks with author and business reporter Christopher Leonard about his seven years of research into the inter-workings of Koch Industries, an American company so big, it's perhaps unknowingly part of your life every day.

Leonard's new book is called Kochland: The Secret History of Koch Industries and Corporate Power in America.

He'll be in Seattle for a book event at Town Hall on Friday, Sept. 6th, 7:30 pm.
