Republican U.S. Senator and Army veteran Tom Cotton is often described as a hawkish conservative for taking a hardline stance on issues like immigration and the Iran nuclear deal. In this interview, Michael Morell steps away from policy and gets a sense of the Arkansas senator’s character, political philosophy and driving influences. Cotton talks about working as his father’s farm hand and learning about his dad’s service in Vietnam. He also discusses his time studying political science and political philosophy at Harvard, and how 9/11 “changed everything,” setting him on the course towards military service and then, the U.S. Senate.
