Previously with the family separation policy it was part of an aggressive campaign led by Stephen Miller personally. There are now a few more people who want to do this as much as he does, all in the administration. It was Trump who hired those people, and then it was Trump who rescinded family separations and fired Neilsen over it, because it made bad media. The public has a template for exactly how to stop it. All that said, this is what the Republican base wants.
