UPDATE 6:22pm ET: A federal judge, in an court order that went public Wednesday, has blocked the government from enforcing the bulk of the president's immigration executive order.

ORIGINAL STORY: Several major tech companies are organizing in opposition to the Trump administration’s executive order that restricts entry or re-entry of citizens from seven Muslim-majority countries. The order, which was signed last Friday, affects immigrants from Iran, Iraq, Yemen, Libya, Somalia, Sudan, and Syria.

Officials from Expedia and Amazon filed formal legal declarations earlier this week in support of Washington state’s federal lawsuit that seeks to overturn the executive order. Both companies said that their employees are directly affected by the president’s policy.

Expedia further explained that its business interests would be negatively impacted if the order is allowed to stand.

Robert Dzielak, Expedia’s general counsel, wrote:

Expedia has and will continue to incur increased business costs to research and understand which of its customers may be impacted by the Executive Order and to assist those customers in making alternative travel arrangements, including canceling and rebooking flights, hotels and other travel services and obtaining refunds and/or credits for those customers from airlines, hotels and other travel suppliers. Expedia is in the process of contacting all affected travelers and continues to incur costs to monitor the impacts of the Executive Order and determine how best to take care of its customers around the globe.

In this case, known as State of Washington v. Trump, the judge ordered Tuesday that the plaintiff must file a supplemental brief to address questions of standing on Wednesday by 6:00pm Pacific Time. The government, in turn, must reply on February 2 by midnight Pacific Time.

“This is not how it should be in America”

Github has also reportedly been organizing a massive effort to get other companies involved in the lawsuit. The company did not immediately respond to Ars' request for comment.

Sheryl Sandberg, the chief operating officer of Facebook, wrote in a public post on Tuesday that the orders "issued over the past week defy the heart and values that define the best of our nation. Families have been separated. Frightened children have been detained in airports without their parents. People seeking refuge have been turned away and sent back to the danger they just managed to flee. This is not how it should be in America."

Citing the example of her own ancestor who was admitted to the United States via Ellis Island in the late 19th century, Sandberg expressed particular concern for female immigrants.

"When the United States turns away people fleeing violence or seeking new lives for themselves and their children, I can’t help but think of the girls and young women whose dreams and futures and safety hang in the balance—young women like my great-great-grandmother Chana," she wrote.

Sandberg was one of several top executives from tech companies, including Apple, Google, and Amazon, who met with Trump in December 2016. In fact, she sat just two seats away from Trump.

Numerous companies have also sent out internal memos to their colleagues, alerting them that their company’s respective leaders are evaluating how to respond to the executive order.

"It’s painful to see the personal cost of this executive order on our colleagues," Google CEO Sundar Pichai wrote in a memo to Google staff obtained by Bloomberg. "We’ve always made our view on immigration issues known publicly and will continue to do so." (Pichai also was one of those at Trump's roundtable last month.)

Emily Iwan, a member of the Salesforce PR team, sent Ars an e-mail distributed to all company employees by its CEO, Marc Benioff.

"America should not forget who we truly are—a nation of immigrants and a light unto other nations," he wrote. "At Salesforce, we believe in equality for all and must ensure that all people are treated fairly, regardless of race, gender identity, abilities, sexual orientation, religion, or national origin."
