The Fifth Circuit Court of Appeals has already declared DACA unconstitutional. It IS undeniably unconstitutional - immigration law is to be legislated by Congress, not promulgated by executive fiat - period, end of story. Therefore, President Trump is correct in recognizing that Barry Soetoro's executive orders underpinning DACA are unconstitutional and should be rescinded in keeping with our laws. This will properly punt this issue to the Congress where it belongs.
