In the past six weeks, nearly 2,000 children have been separated from their parents at the United States' southern border and placed in government-run facilities as part of the Trump administration's “zero tolerance” immigration policy. The policy's sparked backlash from a number of tech's highest profile leaders, including Facebook CEO Mark Zuckerberg , Airbnb's co-founding trio , Uber CEO Dara Khosrowshahi and Apple CEO Tim Cook . Top in-house lawyers in the tech industry have joined in the discussion of Trump's immigration policies as well, using social media platforms to express their views, often with the hashtag #KeepFamiliesTogether. Uber's chief legal officer Tony West echoed his company's CEO in a tweet Tuesday afternoon. The day before, Salesforce general counsel and president of legal Amy Weaver—who has openly advocated for equal pay and LGBT rights in the past—also spoke out against the Trump administration's policy this week. Vijaya Gadde, Twitter's legal, public policy, and trust and safety lead, tweeted Monday that the separation of migrant families “will not be forgotten” and quoted a ProPublica tweet with the audio of crying children separated from their families. The same day, she quoted a tweet about her joint donation to The Refugee and Immigrant Center for Education and Legal Services . Microsoft president and chief legal officer Brad Smith—who has publicly opposed other Trump administration immigration policies in the past—discussed his own visit to a children's immigration holding facility and his company's co-founding of Kids in Need of Defense in a LinkedIn post Sunday. In his post, Smith noted the opportunity to be with one's children on Father's Day was extra poignant “given the news of migrant children being separated from their parents at the US-Mexico border.” His company criticized Trump's policy directly in a Monday blog post .
