BILL MELUGIN: Take a look at this video. Some of these single adult male migrants who are actually smiling and waving at our camera shortly after they crossed illegally. They were a part of a much bigger group — this one about 200 people in total who crossed just down the road from where you saw those river crossings. Again, mostly single adults, sucking up border patrol resources. They're having to go there, process, do the paperwork, and that's why their resources are stretched thin and there are so many mass releases happening.
