They should challenge him in court. I don’t believe the Executive Order is intended to be used in this manner. We do not have a king. We have a chump. And chumps need to work by consensus. Congress should be ready to challenge this president seconds after he tries this, right straight to the SCOTUS. If nothing else on day one, get an injunction. good thought and the best strategy. They should also take the opportunity to educate the American public that our government is not run by the President but that the congress and the court are co-equals. Isolate the imperial president and show the people how grownups handle a petulant child.
