Trump's own people are out there acknowledging that they are the first to do this practice, I don't know what else you need to see to understand that. The stuff from Obama was for unaccompanied minors crossing the border, not young children coming w/ their families.
I mean, from a pure logistical standpoint, you think they just hid thousands of kids previously or some other bizarre conspiracy? There's 11k kids being stuck all over the state and there's nowhere to put them. If there was some precedent for their removal, there'd be facilities to accommodate such a policy.
Your stance here is crazy man. Just admit that it's a shitty practice and Trump's doing it to leverage for his wall. It's that simple; kids for wall.
