What actions, policies and institutions could a President Trump without Congress support use - to find, identify and deport our 10+ million illegals? Serious question.
Executive decree with the help of the National Guard for deportations. The entire legal enforcement of the Executive is at his disposal. Congress already made the laws, he is just enforcing them. That would force Congress to change the laws to allow all of the illegals to stay, and I doubt that would fly.
The questions remains: "HOW does the government go about finding and identifying the illegals in our midst?" What methods could be used to to this?
