The law says the measure they took has already in vigor since 1997. Why is it now a problem?

Phony outrage to go against Trump. Nothing when Obama was doing the same thing. You don't lock up children with criminals. You separate the children from the criminals and the adults entering illegally are criminals.

When America is great again there will be lots of Democrats claiming to their children and their children's children that they were there building the New Great America with President Trump and not trying destroy it and him. Democrat.......Pushing a Dead Donkey.
