I mean, I guess I understand the rationale given here,  but at the same time, this is politically a  really dumb move to be taking at this time. Trump had to have known the  uproar and firestorm of negative press that this would generate for him, right in the middle of several other controversies in which he is simultaneously involved.  He doesn't have nearly the political capital or goodwill towards him and his administration needed to implement this sort of a dramatic reversal in policy. The entire rest of his agenda is in jeopardy now because of his extremely bad timing, and I fully expect this order to be fought by activist 9th Circuit judges and denounced by liberal Democrats everywhere, who will no doubt add it to the list of things for which they feel he deserves to be impeached.
