I don’t believe this for a second. There may be a few whiners blaming Trump, but he has to follow the law and most reasonable people know that.
Congress has to step up and close these loopholes.
He has to obey all lawful rulings but even Soldiers do not have to obey unlawful orders. A single judge just declared that 7 billion people now have constitutional rights. Trump can accept that or exercise his lawful powers to stop it. Of course he may be to busy working out a way to get all the H1Bs in here.
