In her new book, "How Safe Are We?," former Secretary of Homeland Security Janet Napolitano reflects on how secure the U.S. has been since 9/11. According to Napolitano, the most urgent threats America faces are climate change and cybersecurity -- not a crisis at the southern border. We'll talk to Napolitano, who implemented Deferred Action for Childhood Arrivals (DACA) in 2012 under President Obama, about immigration policy under President Trump, the current state of the Department of Homeland Security, as well as her role as president of the University of California system at a time of admissions scandals and free speech controversies.
