OREANDA-NEWS. April 13, 2016. Mark Zuckerberg made it clear that he's no fan of Donald Trump.

Kicking off Facebook's F8 developer conference, the social giant's CEO rejected calls to build more walls and separate people. It was a none-too-veiled shot at the Republican presidential front-runner, who's said that if he's elected, he'll have a wall built along the Mexican border and call for the deportation of millions of illegal immigrants.

"I hear fearful voices calling for building walls and distancing people they label as others," Zuckerberg said onstage. "If the world starts to turn inwards, then our community will just have to work even harder to bring people together."
