Not my problem. Get them the hell out -- all of them -- and let them apply for immigration back into the US like everyone else.
Having said that -- I have no illusions that anyone in government will do that. I suspect Congress uses this as an opportunity to foist some sort of "immigration reform" on us. Trump seems to be challenging them to do just that. In fact if Trump can get votes for tax reform in exchange for some compromise on DACA I can live with that. I can see an argument made that the children of illegals are a separate case of some sort.
As it is now I am not sure Trump has the votes for tax cuts, ObamaCare reform or much of anything. He will have to cut a "deal deal".
How do we deport the parents, uncles, cousins, etc. of these DACA? Once we start giving passes, it will never stop.
