Trump is a rube, but he was correct here.  Those arguing against repealing DACA need to do some research.  Even Obama himself admitted that it was not a permanent fix because that will require congress to actually pass a law.  He admitted this is just temporary until that could be done.  It is unconstitutional.  Those on both sides have admitted this.

Trump is just forcing congress to do something they should have done already.  Pass legislation and make it legal.

Now, had he said, "I don't like DACA.  If you try to pass a bill, I will veto it," then that's another story.  But that is not the case here.

Chin and others are once again playing politics and grandstanding, nothing more.
