After long journey, this migrant’s dream may end in Tijuana

We followed Honduran Karla Cruz from southern Mexico to the U.S. border as she traveled with a caravan of migrants. She hoped to escape violence at home and make it to Texas, where her mother fled 15 years ago. But thousands of miles later, Cruz and her companions faced a closed border and the potential end of a dream. Producer Julia Galiano-Rios and correspondent Nick Schifrin report.
