Don't get your panties in a bunch just yet, everything will be just fine.
https://en.wikipedia.org/wiki/Executive_order
Like both legislative statutes and regulations promulgated by government agencies, executive orders are subject to judicial review and may be overturned if the orders lack support by statute or the Constitution.
Are you sure about an executive order not going into effect for thirty days? I thought that if an executive order needed to be funded ... Congress had thirty days to do so. But send me a link that shows 30 days before going into effect. Just so you know... I hope you are right.
