California congressional candidate Jose Hernandez visits “The War Room” to talk about his personal story and his race against a Republican incumbent. Raised by migrant farmworkers, Hernandez studied engineering in school and went on to help develop mammography technology. He eventually become an astronaut, living the dream he’d had from the age of 9. He says his father put him on the path to success by telling him, “With hard work and an education, you can reach it.” Hernandez says that as an engineer, he’s trained to solve problems — and that’s what he hopes to do in Congress.
