At least 100 tech companies are speaking up against President Trump's travel ban. Recent reports have revealed that several companies have taken part in a "joint legal briefing" against the said ban.

Companies that "filed a joint legal briefing arguing against President Donald Trump's travel ban" included "Apple, Facebook, Google, Microsoft, and Twitter," per MailOnline. The brief was filed last Sunday "with the U.S. Court of Appeals for the Ninth Circuit in support of an ongoing lawsuit against the ban."

The brief charged that the ban "inflicts significant harm on American business, innovation, and growth as a result," based on a copy of the document that was published by several media outlets. According to the brief, lot of immigrants or their children "founded more than 200 if the companies on the Fortune 500 list."

The brief stated, "Immigrants make many of the Nation's greatest discoveries, and create some of the country's most innovative and iconic companies." The document continued, "America has long recognized the importance of protecting ourselves against those who would do us harm. But it has done so while maintaining our fundamental commitment to welcoming immigrants - through increased background checks and other controls on people seeking to enter our country."

The brief added, "The tremendous impact of immigrants on America - and on American business - is not happenstance. People who choose to leave everything that is familiar and journey to an unknown land to make a new life necessarily are endowed with drive, creativity, determination - and just plain guts. The energy they bring to America, is a key reason why the American economy has been the greatest engine of prosperity and innovation in history.

Executives from various top Silicon Valley companies also previously spoke up against the ban that "temporarily barred all refugees and travelers from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entering the United States."

On Friday, after a lawsuit filed by the state of Washington that challenged the ban, a federal judge in Seattle temporarily suspended Trump's order pending a wider legal review, which also allowed "refugees and visa holders from those seven countries to re-enter the country again." 

According to CNN Tech, this isn't "the first legal move by tech firms" against Trump's ban. Last week, Amazon and Expedia filed motions in the Washington attorney general's lawsuit. In it, both companies argued that "the immigration order will hurt their employees and their businesses."
