President Trump needs to immediately rescind the Executive Order amnesties that Obama did. He does that by Executive Order. He can shut DACA down without anyone else involved. Every New DACA recipient is being given two years reprieve. Every new renewal is being given two years forward. If you do not shut the program down it is functioning normally. It will not expire. If it was shut down then no two year renewals could occur, no new applications could be made. Then they expire and no renewals.
