UN: 'Nothing normal' about U.S. detaining immigrant children

More than 650 children were separated from their parents at the U.S. border during a two-week period in May, according to the government’s own figures. On Tuesday, the UN Office for Human Rights condemned the practice and told the U.S. to halt immediately. William Brangham reports that these separations are happening in large part due to Attorney General Jeff Sessions' Zero Tolerance policy.
