Retired Gen. McChrystal on current Pentagon leadership

General Stanley McChrystal was the top commander of American and international forces in Afghanistan in 2009 when his career was cut short. McChrystal resigned after an article in Rolling Stone quoted him and his aides making candid yet disparaging remarks about President Obama and Vice President Biden. He joined Amna Nawaz to discuss his new book, “On Character: Choices that Define a Life.”
