"I'm heartbroken," Sandberg, one of the world's most high-profile business leaders, began. "And deeply concerned."

Whether Washington likes it or not, Silicon Valley is emerging as a political power center.
Trump tried tobefore he was sworn in. The relationship has proved rocky, and tech executives routinely speak out against his policies.
Here's where the president and the tech industry have found themselves at odds.
The first travel ban
Trump issued a travel ban as an executive order just two weeks into his presidency. Citing the threat of terrorist attacks, he sought to establish "new vetting measures to keep radical Islamic terrorists out of the United States." The move angered his political opponents, and protests occurred almost immediately at major airports. The ban was stalled by several US courts.

The white supremacist and Nazi rally in Charlottesville
Trump's response to a deadly rally in Charlottesville, Virginia, proved to be a breaking point for many executives.

The incident eventually led some internet companies, including GoDaddy and Google, to to The Daily Stormer, a neo-Nazi site that promoted the rally.

Apple CEO Tim Cook, who is gay, said, "We are indebted to all who serve. Discrimination against anyone holds everyone back."
The end to DACA
In early September, rumors began circulating that Trump was planning to end DACA, short for Deferred Action for Childhood Arrivals, ahead of a legal challenge to the policy. The program had become a rallying point for Silicon Valley executives, who came together in several lobbying organizations to encourage immigration reform. Many tech companies, including Microsoft, are now committed to.
