Silicon Valley is stepping up its confrontation with the Trump administration.
Today, Uber, Twitter, Netflix and other prominent tech companies are planning to file legal brief opposing the administration's contentious travel ban on immigrants, according to people familiar with the matter.
The amicus brief is expected to be filed with the Ninth Circuit Court of Appeals, 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 travel 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.
Companies backing the filing also include Pinterest, Yelp, Square, Reddit, Kickstarter, Github, Glassdoor, Box, Mozilla, Dropbox, Twilio, Zynga, Medium, Pinterest, and Salesforce, according to the sources, who spoke on the condition of anonymity because the filing was still being finalized today.
Notably, it doesn't appear that Apple, Amazon, Microsoft, Google or Facebook are party to the brief. The sources cautioned the wording of the brief - and the participants - could still change before the filing is made today.
