Apple, Google, Facebook and Microsoft file opposition to Trump's travel ban

Legal brief on behalf of almost 100 tech firms argues immigration ban is illegal and harms innovation, growth and competitiveness

Almost 100 US technology companies have filed a legal brief opposing President Trump's ban on migration from seven Muslim-majority countries, arguing that it imposes significant burdens on the industry by preventing it from hiring talented migrants.

Among the companies signing the filing, an amicus brief supporting Washington state's lawsuit against Trump's order are Apple, Facebook, Google and Microsoft, as well as smaller firms such as Uber, Reddit, Netflix and Dropbox. Notably absent are Amazon, which had previously pledged its support to the Washington lawsuit, and Tesla and SpaceX, the companies of Trump advisory council member Elon Musk. An Amazon spokesperson said that the company was advised by the Washington attorney general to not join the amicus brief, since the company acted as a witness in the original lawsuit.
