America's Stealth War on the Mexico BorderJun 25, 201923mGuest: John Carlos Frey, Investigative Journalist and Filmmaker, Author of “Sand and Blood: America’s Stealth War on the Mexico Border” Some –but not all -of the 350migrant children held for weeks in squalid conditions in a Border Patrol facility in Texas have reportedly been moved to a safer location. Customs and Border Patrol officials say they are not equipped to handle the deluge of migrants arriving at the southern border –more than half a million people since October. The Department of Health and Human Services says next week it will run out of money to care for unaccompanied migrant children and has requested nearly $3 billion in emergency funds from Congress. But some Democrats are reluctant to approve the funding because they oppose the Trump Administration’s underlying immigration policies.
