Border officials in Texas say they are seeing a sharp increase in migrant apprehensions, as many as 1,000 a day. To handle the surge, U.S. Customs and Border Protection officials have begun releasing migrants from detention with a "notice to appear" in court at a later date. It is a policy similar to the one the White House halted last year. Homeland Security Secretary Kirstjen Nielsen was at the border Thursday. Mireya Villarreal asked Nielsen about the apparent policy change.
