Will keep attending business council meetings: Elon Musk

"The order inflicts significant harm on American business, innovation, and growth", the brief states, adding that it "makes it more hard and expensive for USA companies to recruit, hire, and retain some of the world's best employees".

But Monday, Musk's companies were among the 30 more that joined the amicus, including Adobe Systems Inc.

Participating technology companies include household names Airbnb, Facebook, Google, Intel, Netflix, Snap and Uber Technologies. Separately, companies including Groupon and Pivotal software have filed their own letters supporting the amicus brief.

That makes more than 125 overwhelmingly tech-focused companies that have signed the brief, which was filed Sunday evening in the 9th U.S. Circuit Court of Appeals in San Francisco. We said that Tesla CEO Elon Musk was approaching his political differences with President Donald Trump from a personal, not a legal angle.

Unlike many other times in his groundbreaking career, Tesla´s boss Elon Musk has been in the spotlight for quite uncomfortable reasons, given the fact that while many tech leaders has stood against president Trump´s Muslim ban, and some of his advisory council has resigned, Musk made a decision to stay in this position, despite the incredible numbers of criticism he has received. "How could having only extremists advise him possibly be good?"

"Musk's last tweets on the immigration issue were on February 5, when he wrote", Activists should be pushing for more moderates to advise President, not fewer.

That comment was retweeted by AOL founder turned investor Steve Case, who added a link to a self-penned Medium post echoing the same refrain while lamenting the absence of former President Roland Reagan. The forty-five-year-old tech billionaire also said that he was able to steer the council agenda to focus on issues such as immigration and climate change.

According to Musk, he specifically asked for the immigration ban to be the primary subject, as he assures that the request was accepted. The challengers won an initial victory on Friday when a federal judge issued a temporary restraining order to force a suspension of the president's immigration ban.

Musk publicly criticized the travel ban in one tweet as "not the best way to address the country's challenges". An appeals court declined to immediately reinstate the immigration restrictions over the weekend.

"The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned", Trump wrote in a tweet.

That brings the total number of companies who've cosigned the friend of the court brief to 127.
