A proposed border wall in Big Bend is raising concerns among local sheriffs, lawmakers and residents who say steel barriers could damage one of the most iconic landscapes in Texas. In this episode of Immigration Crisis: The Fight for the Southern Border, we travel deep into one of the most remote stretches of the U.S. Mexico border to examine the debate over security, technology and tourism. Hosted by Edward R. Murrow Award winning podcast host and Emmy winning investigative journalist Yami Virgin, with photojournalist and editor Paul Sanchez.
