In the last few days, Vice President Kamala Harris has kicked her presidential campaign into high gear, speaking to voters in Wisconsin, Indianapolis, and Texas. She's already picked up the endorsement of leading Democrats, including former president Barack Obama. Soon after Kamala Harris became vice president, CNN's Abby Phillip sat down with her to talk about her immigrant routes, the difficulties and controversies she faced as a district attorney and attorney general in California, as well as her journey from prosecutor to politician.
