We do not have a policy of separating families at the border," Homeland Security Secretary Kirstjen Nielsen tweeted. President Trump's top domestic policy adviser, Stephen Miller, was quoted in Sunday's New York Times touting the crackdown. "It was a simple decision by the administration to have a zero tolerance policy for illegal entry," he said. "Period." DHS announced last week that around 2,000 children have been taken from their families during the six weeks since the policy went into effect, and officials acknowledge the number may be even higher. More than a month after Attorney General Jeff Sessions announced Trump's new "zero tolerance" policy to great fanfare, members of the administration continue to struggle with how to talk about it - alternating between defending the initiative as a necessary deterrent, distancing themselves, blaming Democrats, trying to use it as leverage for negotiations with Congress or denying that it exists at all. Former first lady Laura Bush compares what's happening to Japanese internment: "I appreciate the need to enforce and protect our international boundaries, but this zero-tolerance policy is cruel. It is immoral. And it breaks my heart. Our government should not be in the business of warehousing children in converted box stores or making plans to place them in tent cities in the desert outside of El Paso. People on all sides agree that our immigration system isn't working, but the injustice of zero tolerance is not the answer."
