Apple, Facebook, Google, Microsoft, and 93 other technology companies have filed an amicus brief opposing Trump’s immigration ban. From The Washington Post:

On Sunday night, technology giants Apple, Facebook, Google, Microsoft, Netflix, Twitter, Uber and many others filed a legal brief opposing the administration’s contentious entry ban, according to people familiar with the matter. The move represents a rare coordinated action across a broad swath of the industry — 97 companies in total— and demonstrates the depth of animosity toward the Trump ban.

The amicus brief was filed with the U.S. Court of Appeals for the 9th Circuit, which is expected to rule within a few days on an appeal by the administration after a federal judge in Seattle issued late Friday a temporary restraining order putting the entry ban on hold. The brief comes at the end of a week of nationwide protests against the plan — as well as a flurry of activity in Silicon Valley, a region that sees immigration as central to its identity as an innovation hub.

For those curious what an amicus brief is:

Amicus briefs are legal documents filed in appellate court cases by non-litigants with a strong interest in the subject matter. The briefs advise the court of relevant, additional information or arguments that the court might wish to consider. Briefs can also focus the court’s attention on the implications of a potential holding on an industry, group, or jurisdiction not represented by the parties.
