• Nearly 400 leaders of American businesses signed a letter asking Trump and Congress to save DACA prtections for "dreamers."
  • Signers include the CEOs of Facebook, Amazon, Apple, Cisco, Microsoft and Visa.

In an open letter, nearly 400 U.S. executives, including Facebook's Mark Zuckerberg and Amazon's Jeff Bezos, urged President Donald Trump to retain protections for immigrant "dreamers."

The letter, posted Thursday, says the U.S. economy would lose hundreds of billions of dollars if workers and students currently protected by the Deferred Action for Childhood Arrivals program were deported.

Other notable CEO co-signers include Apple's Tim Cook, Cisco's Chuck Robbins, Microsoft's Satya Nadella and Visa's Alfred Kelly. Their companies are among the 30 that make up the Dow Jones industrial average.
