Secretary John King has seen the U.S. education system from almost every conceivable angle. He started his career as a history teacher and middle-school principal before going on to serve as New York State education commissioner and then as President Obama's education secretary during his second term. Today, he is a college professor and president of an education nonprofit. He is also running for governor of Maryland! In this episode, we talk about civics and the importance of covering the problematic parts of American history and culture.
