Facebook CEO Mark Zuckerberg Slams Donald Trump

Facebook CEO Mark Zuckerberg attacked Republican presidential candidate Donald Trump's extreme stance on refugees and immigrants during a speech on Tuesday, criticizing "fearful voices for building walls and distancing people they view as others." The founder of the social network spoke about Facebook's goal of sharing ideas during his company's annual F8 developer conference in San Francisco, when he said "instead of building walls, we can help build bridges," by welcoming refugees and immigrants. "It takes courage to choose hope over fear," he said. "Whether we are welcoming a refugee fleeing war or an immigrant seeking opportunity." Facebook launched the FWD.us immigration reform lobbying group in 2013, which advocates for legislation that supports a more open worker visa process.
