here's a transcript from WH briefing:
NIELSEN: So I want to be clear on a couple of other things. The vast majority, vast, vast majority of children who are in the care of H.H.S. right now — 10,000 of the 12,000 — were sent here alone by their parents. That is when they were separated. So somehow we’ve conflated everything. But there is two separate issues. 10,000 of those currently in custody were sent by their parents with strangers to undertake a completely dangerous and deadly travel alone. We now care for them. We have high standards. We give them meals, we give them education, we give them medical care. There is videos, there is TVs, I visited the detention centers myself — that would be my answer to that question.
