The policy team at the White House developed the executive order on refugees and visas, and largely avoided the traditional interagency process that would have allowed the Justice Department and homeland security agencies to provide operational guidance.....
Friday night, DHS arrived at the legal interpretation that the executive order restrictions applying to seven countries -- Iran, Iraq, Libya, Somalia, Syria, Sudan and Yemen -- did not apply to people with lawful permanent residence, generally referred to as green card holders.
The White House overruled that guidance overnight, according to officials familiar with the rollout. That order came from the President's inner circle, led by Stephen Miller and Steve Bannon. Their decision held that, on a case by case basis, DHS could allow green card holders to enter the US

Before the President issued the order, the White House did not seek the legal guidance of the Office of Legal Counsel, the Justice Department office that interprets the law for the executive branch.

K Drum suspects it's planned by Bannon

In cases like this, the smart money is usually on incompetence, not malice. But this looks more like deliberate malice to me. Bannon wanted turmoil and condemnation. He wanted this executive order to get as much publicity as possible. He wanted the ACLU involved. He thinks this will be a PR win.

In any case it is becoming quite clear who is Trumps chief Wormtongue as he tries to rule by edict.  

Inside the West Wing, it is almost impossible for some aides to know what is in the executive orders, staffers say. They have been written by Stephen Miller, Trump's senior White House adviser for policy, and Steve Bannon, Trump's chief strategist, according to people familiar with the matter.

President Trump reshuffled the National Security Council to include his chief strategist, Stephen Bannon, and limited the roles of the director of national intelligence and the chairman of the Joint Chiefs of Staff.

restrained from... removing individuals

prohibits the govt from sending those people currently in u.s. airports back to their countries.  and that this is the only thing the judge ruled on.  im unclear how this ruling squares with this excerpt from the k-1 visa site (which applies generically) that people ate not in the u.s. at a port-of-entry:

A visa allows a foreign citizen to travel to the U.S. port-of-entry and request permission to enter the United States.

"It seems that a lot of the chaos yesterday could have been avoided, had you at least included some sort of timed grace period," Chuck Todd asked Priebus on NBC News' "Meet the Press." "Why was that not included?" "Well, I don't think you want to have a grace period," Priebus replied. "Then people that want to do bad things to Americans will just move up their travel date two days in order to get into the country before the grace period's over."

Priebus later said it is possible for President Trump's immigration ban to be expanded to "other countries that have similar problems" in the future.

because they are reporting that:

* 57% favor a temporary ban on refugees from the countries in trump's EO with an additional 10% undecided.

 * 56% favor a temporary block on visas prohibiting residents of the countries listed in trump's EO from entering the u.s. with an additional 11% undecided.
