The chief executives of Apple, Amazon, Facebook and Google joined roughly 300 business leaders urging President Donald Trump late Thursday to continue protecting children brought illegally to the United States from being deported.

Since 2012, the U.S. government has allowed those children — young adults now known as Dreamers — to continue living in the country as long as they obtain and renew work permits under a program called Deferred Action for Childhood Arrivals, or DACA.
