 This is Pulitzer on the Road, a program that delves into the stories behind Pulitzer Prize winners and their remarkable work. In this program, we travel to El Paso, Texas, with Caitlin Dickerson, who reported on the Trump administration's zero-tolerance policy regarding family separations at the border. El Paso, a city of about 700,000, sits in the far western corner of Texas, bordered by New Mexico to the west and the north and Mexico to the south.
