Mark Zuckerberg took to Facebook this afternoon to speak out about Trump's executive orders on immigration.
He also took the opportunity to applaud Trump's pledge to "work something out" for Dreamers, or immigrants who were illegally brought to the U.S. as kids. His organization, FWD.us, will work with the administration on this, he said. And he made a case that everyone benefits when "the best and brightest from around the world can live, work and contribute here."
Why Silicon Valley cares: Beyond personal reasons (Zuckerberg notes that his family and his wife's family immigrated from elsewhere), tech companies have real workforce issues to consider. A large number of so-called Dreamers live and work at these companies, and they also have a lot of engineering and technical jobs they need to keep filling through temporary visas for highly skilled workers.
