I don’t know that he saw those pictures either. I had to look it up because you keep referring to them. It seems as though you are referring to some photos showing kids in “cages” taken in 2014, which a few liberals mistakenly showed kids that were separated from their families by immigration enforcement under Trump.
The important difference there is that was not an Obama manufactured humanitarian crisis, while this one is manufactured by Trump. The kids in the 2014 photos were not separated from their families by US officials, rather they showed up in waves from Central America without their parents. The kids were held here until they could be transferred to HHS shelters before being connected with family or being put into foster care.
