In just the first seven days of his presidency, Donald Trump has signed executive orders for the Mexico border wall, withholding federal funding from sanctuary cities and blocking refugees from nations like Iran, Iraq, Libya and Syria.

Seems like, Trump’s anti-immigration policies and his plans to build a wall along the border with Mexico have upset Facebook CEO Mark Zuckerberg who strongly hit out at the USA President.

"Like many of you, I'm concerned about the impact of the recent executive orders signed by President Trump. We need to keep this country safe, but we should do that by focusing on people who actually pose a threat," Mark Zuckerberg wrote in a Facebook post.

The Facebook CEO also criticised Donald Trump's actions by saying the US is a "nation of immigrants". Mark Zuckerberg's great-grandparents had come to the US from Germany, Austria and Poland, while his wife Priscilla Chan's parents were refugees from China and Vietnam.

"Had we turned away refugees a few decades ago, Priscilla's family wouldn't be here today," Mr Zuckerberg said adding, “We need to keep this country safe, but we should do that by focusing on people who actually pose a threat. Expanding the focus of law enforcement beyond people who are real threats would make all Americans less safe by diverting resources, while millions of undocumented folks who don't pose a threat will live in fear of deportation.”
