>> Apple, Google, Twitter and Microsoft are among nearly 100 tech companies who on Monday morning filed a legal briefing opposing US President Donald Trump's immigration ban. The brief says Trump's Executive Order represents a sudden shift in the rules governing entry into the US and inflicts harm on American companies.
It also points out that immigrants or their children founded more than 200 of the companies on the Fortune 500 list. Trumps immigration ban faces a crucial legal hurdle on Monday afternoon that could determine whether he can push through with the order that temporarily bars entry of people from seven mostly Muslim countries.
A federal appeals court in San Francisco will hear from the Justice Department on why the travel ban should be re-instated. The court is expected to act quickly, and a decision either way may ultimately result in the case reaching the US Supreme Court.
