The current administration is doing nothing wrong at all. Unless you want to throw kids in jail cells with parents who commit crimes then they get separated.
And yes, they are committing a crime.
And no, they are not asylum seekers because they are not fleeing political persecution or some sort of persecution from an authoritarian regime.
They are criminals. They came here, committed a crime, and dragged their kids into it, and now they got separated. Its all their own fault.
