The children were being driven to school, as they apparently are each day:
“When they got in line at the border at 4 a.m. Monday, traffic was moving slow.”
Huh? I’m upset about the little girl being detained away from her parents, but I’m also really confused why she’s leaving for school in the middle of the night. I can sort of understand why the border patrol agents would question two children alone at 4 am. Maybe I’m naive but that doesn’t seem like a normal occurrence to me.
