After issuing statements over the weekend condemning President Donald Trump's executive order limiting immigration from seven predominantly Muslim countries and temporarily halting the acceptance of refugees into the U.S., some tech companies are convening to consider their legal options.

According to Reuters, San Francisco-based software maker Github is arranging the meeting to discuss whether to file an amicus, or friend of the court, brief in one of a handful of lawsuits filed against the Trump administration over the order. The move comes after Seattle-based Amazon and Expedia filed declarations in support of a lawsuit filed by the state of Washington's attorney general.

A source told Reuters that the companies invited to meet include: Adobe, Airbnb, Alphabet, Box, Dropbox, Etsy, Evernote, Medium, Netflix, Pinterest, Reddit, Salesforce, SpaceX, Stripe, and Yelp. However, it's unclear how many companies have accepted the invitation. A Box spokesperson confirmed to Reuters that it would attend the meeting. A representative for Etsy confirmed that the company received the invitation, but would not comment on whether someone from the company would attend.

While Trump signed the immigration order on Friday, the ways in which Silicon Valley is expressing its opposition continue to grow. Yesterday, Alphabet employees from offices around the world organized a walkout in protest of Trump's policy. According to USA Today, an estimated 2,000 employees participated in the walkout.
