>> "all in" starts right now. good evening from new york, i'm chris hayes. u.s. immigration policy is in chaos thanks solely to donald trump after the humanitarian crisis he initiated which threw every federal agency involved from the department of justice to homeland security to health and human services to now the pentagon into pandemonium. as over 2,000 children were for ostensibly no reason ripped from their parents and sent to facilities around the country, scattered to the four winds, and there are still no plans for reuniting them. today with a casual tweet, the president then blew up plans by congressional republicans to pass an immigration bill. there's no coordination among agencies with confusion along the border as officials try to figure out what they're supposed to do now. the only thing consistent about the president's immigration policy is, frankly, its cruelty. "the washington post" is reporting on the difficulty of reuniting children with their parents.
