U.S. Ramps Up Border Militarism as Trump Appoints DHS Head General John Kelly to Chief of Staff

President Donald Trump on Wednesday embraced a proposal to slash the number of immigrants allowed into the U.S. by half, in what would be the biggest overhaul of immigration law in over half a century. The RAISE Act would create a so-called merit-based immigration system that would favor applicants who speak English, have advanced degrees or can demonstrate job skills. The announcement comes as Trump replaced his ousted chief of staff, Reince Priebus, with retired General John Kelly, who was head of the Department of Homeland Security. We speak with two-time Emmy Award-winning journalist John Carlos Frey, whose new investigation in partnership with ABC's "20/20" is titled "Life and Death at the Border."
