Actually what he said in the beginning was that everyone here illegally would have to leave. Some could come back, but only after they got in line. Remember him talking about the big beautiful door in the wall?
Yes, that’s true. However, it was undefined. When he refined what he meant he gave that sequence: wall, criminals, talk.
He can still insist DACA get legal entry, but expedite it. That would be “good ones come back”.
