On Friday, January 27, 2017, by Executive Order, President Donald Trump imposed a 90-day ban that affects travel to the U. S. by citizens of Iraq, Syria, Iran, Sudan, Libya, Somalia, and Yemen and puts an indefinite hold on a program resettling Syrian refugees.

On Monday, January 30, Acting Attorney General Sally Yates, a Democratic appointee, directed Justice Department attorneys to not defend President Trump’s controversial executive refugee and immigration ban.  She declared Monday she was not convinced that the order was lawful. Her directive was likely to be temporary, given that Senator Jeff Sessions, Trump’s pick for Attorney General, will likely move to uphold the President’s policy. Sessions is awaiting Senate confirmation.

Still, Yates’ abrupt decision deepened the chaos surrounding Trump’s order. At least three top National Security officials–Defense Secretary James Mattis, Homeland Security Secretary John Kelly, and Rex Tillerson, who is awaiting confirmation to lead the State Department–have told associates they were not aware of details of the directive, until around the time Trump signed it. Leading intelligence officials were also left largely in the dark, according to U. S. officials.

Tennessee Senator Bob Corker, the top Republican on the Senate Foreign Relations Committee, said that, despite White House assurances that Congressional leaders were consulted, he learned about the order in the media.

The fallout was immediate:  friction between Trump and his top advisers; a rush by the Pentagon to seek exemptions to the policy; an unusually public clash between a President and the civil servants tasked with carrying out his policy.

A large group of American diplomats circulated a memo voicing their opposition to the order, which temporarily halted the entire U. S. refugee program and banned all entries from seven Muslim-majority nations for 90 days. In a startling combative response, White House spokesman Sean Spicer challenged those opposed to the measure to resign.

“They should either get with the program, or they can go,” Spicer said.

The blowback underscored Trump’s tenuous relationship with his own National Security advisers, many of whom he met for the first time during the transition, as well as with the government bureaucracy he now leads. While Trump outlined his plan for temporarily halting entry to the U. S. from countries with terror ties during the campaign, the confusing way in which it finally was crafted stunned some who have joined his team.

Mattis, who stood next to Trump during Friday’s signing ceremony, is said to be particularly incensed. A senior U. S. official said Mattis, along with Joint Chiefs Chairman Joseph Dunford, was aware of the general concept of Trump’s order, but not the details. Tillerson has told the President’s political advisers that he was baffled over not being consulted on the substance of the order.

U. S. officials and others with knowledge of the Cabinet’s thinking insisted on anonymity, in order to disclose the officials’ private views.

Trump’s order pauses America’s entire refugee program for four months and indefinitely bans all those from war-ravaged Syria. Critics dispute the President’s assertion that the policy is needed to keep Americans safe, noting that recent acts of extremist violence have been carried out either by U. S. citizens or by individuals whose families weren’t from the Nations singled out in the order.

The President has privately acknowledged flaws in the roll out, according to a person with knowledge of his thinking. But he’s also blamed the media–his frequent target–for what he believes are reports exaggerating the dissent and the number of people actually affected.

Trump has also said he believes the voters who carried him to victory support the plan, as a necessary step to safeguard the Nation. And he’s dismissed objectors as attention-seeking rabble-rousers and grandstanding politicians.

After a chaotic weekend during which some U. S. legal permanent residents were detained at airports, some agencies were moving swiftly to try to clean up after the White House.

Homeland Security, the agency tasked with implementing much of the refugee ban, clarified that customs and border agents should allow legal residents to enter the Country. The Pentagon was trying to exempt Iraqis who worked alongside the U. S. and coalition forces from the 90-day ban on entry from the predominantly Muslim countries. “There are a number of people in Iraq who have worked for us in a partnership role, whether fighting alongside us or working as translators, often doing so at great peril to themselves,” said Navy Captain Jeff Davis, a Pentagon spokesman.

Policies with such broad reach are typically vetted by affected agencies and subject to review by multiple agencies. It’s a process that can be frustratingly slow but is aimed at avoiding unintended consequences.

On Capitol Hill, lawmakers in Trump’s party sought to distance themselves from the wide-ranging order.

While Spicer said “appropriate committees and leadership offices” on Capitol Hill were consulted, GOP lawmakers said their offices had no hand in drafting the order and no briefings from the White House on how it would work.

“I think they know that it could have been done in a better way,” Corker said of the White House.

The Executive Order was largely crafted by Steve Bannon, Trump’s chief strategist, and Stephen Miller, a young policy adviser and former Congressional aide to Trump’s pick for Attorney General, Senator Sessions. Spicer insisted the advisers had kept departments “in the loop at the level necessary,” but he sidestepped questions about whether Cabinet Secretaries were directly involved in the process.

Some Trump supporters defended the President, saying his actions should not have come as a surprise, given his positions during the campaign.

“Nothing he did over the weekend was new,” said Newt Gingrich, the former House Speaker and an informal adviser. He conceded that coordination could have been better, but he said Trump’s vow to quickly bring change to Washington will sometimes mean he needs to prioritize fast action over broad consultation.

“If you’re the reformer, you need the momentum,” Gingrich said.
