Tech leaders respond to immigrant ban
Google's Sundar Pichai and Facebook's Mark Zuckerberg spoke out against Trump's executive order banning people from seven Muslim-majority countries from entering the U.S.
Facebook's Mark Zuckerberg said he's concerned about the impact of the orders and that the U.S. should keep its doors open to refugees.
Why Silicon Valley cares: Tech companies have real workforce issues to consider. A large number of immigrants work at these companies. Silicon Valley companies rely on temporary visas for high-skilled foreign workers to fill thousands of engineering and technical jobs say they can't fill with domestic talent. Trump has been hostile to any visas that he sees as taking jobs from Americans.
