It’s been 18 years since September 11, 2001, but has America ever recovered? We will never forget, but we also must remember the unity we had on 9/12. Best-selling author Brad Meltzer joins to discuss his personal story of 9/11 and his new children’s book, “I Am Walt Disney.” Garrett M. Graff, author of “The Only Plane in the Sky: An Oral History of 9/11,” discusses his book, which is composed entirely of quotes from the people who were there – in the towers, on the planes, with the president, and everywhere in between.
