Customs and Border Protection show the flow of unaccompanied minors crossing the border continues unabated along with other immigrants claiming asylum. There is no impeding at the moment.
As I recall, Sessions is more solid than Trump on immigration. When the mass media started shrieking about how terrible it is to “separate families at the border,” Sessions defended doing so, and rightly so. When you’re detained or incarcerated for any other violation of the law, you don’t get to take your hijos (nor your tia or abuela) to jail with you. In contrast, Trump caved to the media and public pressure and put an end to the policy.
