Silicon Valley took the lead over the weekend in corporate resistance to President Donald Trump's clampdown on immigration, financing legal opposition, criticizing the plan, as well as helping employees ensnared by his executive order. In an industry that has long depended on immigrants and celebrated their contributions – as well as championing liberal causes such as gay rights – there was little initial consensus on exactly how to respond to Trump's move on Friday. The action triggered a global backlash, and sowed confusion and anger after immigrants, refugees and visitors were kept off flights and left stranded in airports.
