There is much to criticize about President Trump’s executive order on immigration, particularly the slapdash way the Administration drafted the order and announced it to the agencies responsible for implementing it. The Administration apparently bypassed the normal interagency review process, which checks orders for legality and advises on possible consequences. No doubt the Administration calculated that it couldn’t trust Obama holdovers not to create obstacles—a calculation that seems to have been correct in some cases. But lawyers do help sometimes, and it’s wise to listen even to bureaucrats on occasion. The normal interagency review could have avoided much of the confusion at airports over the weekend, which benefited no one, and which created a sense of disorder which will not help the Administration in the future. It would have been much better for the Administration to wait until its new team was fully in place, including its Attorney General, before taking legal action bound to inflame many people.
