Lee Gelernt of the ACLU Immigrants' Rights Project said Tuesday that "Children are begging and screaming not to be separated from their parents, as they're hauled off to different cities. It's a harrowing situation, one that the president himself called horrible. No law even remotely requires the separation of children, and we filed a recent lawsuit arguing, in fact, that the Constitution prohibits this policy."
In an interview with NPR's Morning Edition host Steve Inskeep Tuesday, former President Barack Obama's domestic policy director, Cecilia Muñoz, stated unequivocally that separating children from their parents was not a policy the Obama administration followed.
"The Obama administration did not do that, no. We did not separate children from their parents," Muñoz said. "This is a new decision, a policy decision put in place by the attorney general," which Muñoz said "puts us in league with the most brutal regimes in the world's history."
