Mark Zuckerberg on DACA repeal: 'This is a sad day for our country'

Mark Zuckerberg is taking his strongest political stance yet—and calling for action.

Just minutes after Attorney General Jeff Sessions announced the repeal of the DACA immigration program, the CEO of Facebook posted on Facebook.

"This is a sad day for our country. The decision to end DACA is not just wrong. It is particularly cruel to offer young people the American Dream, encourage them to come out of the shadows and trust our government, and then punish them for it," Zuckerberg wrote.

On Monday, the Trump administration announced the repeal of Deferred Action for Childhood Arrivals (DACA), a program that protected the children of illegal immigrants from being deported in the United States. The Obama administration introduced the program in 2012 as it tried to reform the country's immigration policies. 

Zuckerberg has been quite outspoken about the need for more reform in immigration policy in the United States. He is the leader behind FWD.us, a lobby group focused on the matter. That organization sent a letter to President Trump last week, urging them to keep DACA in place. Hundreds of CEOs from major tech companies, including Apple, Google, Amazon, and Uber, signed on. 

Despite the amount of money and time and the words Zuckerberg has written and spoken about immigration, the program was repealed. 

But the fight isn't over yet. Zuckerberg is encouraging Congress to pass new legislature to support Dreamers, the name given to immigrant children who qualify for the act to grant them a pathway to citizenship. 

"For years, leaders from both parties have been talking about protecting Dreamers. Now it's time to back those words up with action. Show us that you can lead. No bill is perfect, but inaction now is unacceptable," Zuckerberg wrote. 

Of course, Zuckerberg isn't the only one in Silicon Valley taking issue with the removal of DACA. 

Google CEO Sundar Pichai tweeted his support for Dreamers shortly after the repeal. 

Susan Wojcicki, CEO of Google's YouTube, tweeted similar sentiment to Pichai.

Apple CEO Tim Cook had tweeted his support prior to the repeal.

He shared a longer letter with employees on Monday, where he highlighted the work that Dreamers do at Apple and beyond.

"They help customers in our retail stores. They engineer the products people love and they're building Apple's future as part of our R&D teams," Cook wrote. 

Microsoft CEO Satya Nadella wrote a letter titled "DREAMers make our country and our communities stronger" and shared it on LinkedIn. Microsoft's President and Chief Legal Officer shared another note shortly after the repeal, calling for "urgent DACA legislation." 

A Slack spokesperson wrote in an email, "We strongly oppose ending DACA, which would harm thousands of hard working young people who make our community thrive and eliminate their contributions to the US economy." 

Uber CEO Dara Khosrowshahi, who was appointed to role last month, emigrated to the United States from Iran as a child and tweeted about his support. 

Travis Kalanick, Uber cofounder and former CEO who was ousted in June, celebrated Khosrowshahi's leadership.

Twitter CEO Jack Dorsey shared a Twitter Moment, a curated collection of tweets, related to DACA being rescinded. 

This post was updated with more commentary from tech CEOs.
