Elon Musk’s Tesla and SpaceX joined a legal brief filed by organisations opposed to President Donald Trump’s order restricting immigration from 7 countries including Syria, Iran, Somalia, Iraq, Sudan, Yemen and Libya, according to a court filing.
Musk agreed to enter into Trump’s business advisory council in December, and has advocated talking about issues directly with the president. Uber chief executive Travis Kalanick quit the council recently amid mounting pressure over Trump’s travel ban.
