welcome back to "the messy truth." i'm van jones. trevor noah still here with me. listen, during his campaign rallies, donald trump could always rely on his one big moment, talking about that wall he was going to build. meanwhile, down on the actual border, millions of people are living on the front line of the whole border battle. and they're dealing with real-life immigration issues every single day. and a lot of them are trump voters and a lot of those trump voters are latinos. so i took a road trip to meet with some of them. >> this is where the debate over border security starts. the arizona/mexico border. i went to see it for myself and talk to the people who live this reality every day, like the pinal county sheriff's deputies.
