Steve Schmidt talks with Brian Stelter about his headline-making "war" with John McCain's family. Schmidt explains why he is sharing secrets from McCain's 2008 campaign; how his stories have relevance for political journalists; and why he feels compelled to annotate history now. Schmidt also discusses challenges for the press and says the next few years are going to be "wild and chaotic and dangerous:" 2024, he believes, "could be a last choice election."
