Scottish Independence, Lithium, and Behind the Scenes at Camp David

We check in on the Scottish independence vote happening today. Results come in tomorrow. Then, we move on to the countries most closely watching the referendum; could it spur separatist movements in Spain, Canada, Turkey… or even Texas? Next up, Pulitzer Prize-winning journalist Lawrence Wright joins us to talk about his latest book, Thirteen Days in September, a behind-the-scenes account of the negotiations leading to the historic 1978 Camp David Middle East peace agreement. Finally, lithium -- a naturally occurring element also used to treat mental illness -- is in our drinking water supply. Could it be a good thing?
