daca was enacted by president obama on his executive authority. it can be rescinded by president trump on his executive authority. one more effectiveness, though, there has been a lot of talk about deal on capitol hill for daca legalization in favor of the wall or some other policies the president wants. democrats don't need the deal. the courts are going to keep daca alive and possibly restorative. they are doing their work for them. >> bret: mollie, it seems like it's common sense that this thing was not set up legislatively, and would need to come if it had to go forward, so reading between the lines, the federal judges looking for a better explanation? >> the constitution gives the authority for this type of program to congress. congress is the one that should be doing this. a very similar type of program that president obama had was ruled unconstitutional in state attorney general challenged. it would be exactly the same situation with this one.
