Well it seems the "editorial board" has come around to my way of thinking. President Obama, because he couldn't get his own party when it was in the majority pass any immigration reform,   by executive order, made up a special name and program for about 800,000 mostly young people brought here as children.
But, the program has left them in a sort of limbo that President Trump now wants to clean up the mess from. The only way he can force the hand of Congress, on both sides of the aisle, is to declare the program to end in 6 months.
This way both parties are responsible if there is no legislation passed to help them.  No one wants the blame for not creating a clear path to citizenship for these mostly contributory young folks that by no fault of theirs were brought here.  The far majority of these young people are over the age of 18. Once becoming U.S. Citizens they can visit any out of country family and return without a problem. Eventually applying to bring some here if they wish.
