Thirty more tech companies have signed a brief opposing President Donald Trump’s travel ban, bringing the total number involved to 127.

Tesla, Adobe, HP and Evernote are among the new signatories.

They join 97 other companies which have filed a legal document stating the ban “inflicts significant harm” on their businesses and is unconstitutional.

The amicus brief allows parties not directly involved in a case but who feel affected by it, to give a view.

It was filed in Washington on February 5 and also includes Apple, Facebook and Microsoft as signatories.

Amazon is not part of the amicus brief but it is a witness in the original lawsuit brought by the Washington state Attorney General.

President Trump’s executive order halted the entire US refugee program for 120 days, indefinitely banned Syrian refugees and suspended permission to enter the US for all nationals from seven Muslim-majority countries.

There is currently a nationwide temporary restraining order in place, which was issued on February 3 by a federal judge in Washington.

This means visa holders from Iraq, Syria, Iran, Libya, Somalia, Sudan and Yemen will be allowed to enter the US until the full case has been heard.

However, Donald Trump has said he will fight the order as it puts national security at risk.

The tech group’s brief reads: “Of course, the federal government can and should implement targeted, appropriate adjustments to the nation’s immigration system to enhance the nation’s security.

“But a broad, open-ended ban – together with an indication that the ban could be expanded to other countries without notice – does not fit the goal of making the country more secure. Instead, it will undermine American interests.”
