America's business leaders are speaking out against President Trump's move to end DACA.

The president of Microsoft, Brad Smith, took a notable stand. He said not only will his company lobby for a legislative solution but also that Microsoft is calling on Congress to make immigration the top priority, before tax reform. And he is calling on other business leaders to follow suit.

"There is nothing that we will be pushing on more strongly for Congress to act on," Smith said in an interview with NPR. "We put a stake in the ground. We care about a tax reform bill. The entire business community cares about a tax reform. And yet it is very clear today a tax reform bill needs to be set aside until the DREAMers are taken care of. They have a deadline that expires in six months. Tax reform can wait."

Smith also said if the government moves to deport DREAMers who are Microsoft employees, "it's going to have to go through us to get that person."

This is the second time in a week that Smith has spoken out. Last Thursday, Smith and Microsoft CEO Satya Nadella both issued statements calling on the administration to preserve DACA. Nadella, a first-generation immigrant from India, struck a personal note: "I am a product of two uniquely American attributes: the ingenuity of American technology reaching me where I was growing up, fueling my dreams, and the enlightened immigration policy that allowed me to pursue my dreams."

Meanwhile, in a letter to employees this morning, Apple CEO Tim Cook said more than 250 Apple workers are affected by the DACA repeal and that he has been hearing from them all weekend.

"I want to assure you that Apple will work with members of Congress from both parties to advocate for a legislative solution that provides permanent protections for all the Dreamers in our country," Cook said.

Dozens of CEOs including Jeff Bezos of Amazon, Reed Hastings from Netflix, Randall Stephenson from AT&T and Tim Sloan of Wells Fargo wrote a letteraddressed to the president asking him to preserve the program.

The leaders argued that all DACA recipients grew up in America and give back to the community and pay income taxes. They said: "More than 97 percent are in school or in the workforce, 5 percent started their own business, 65 percent have purchased a vehicle, and 16 percent have purchased their first home. At least 72 percent of the top 25 Fortune 500 companies count DACA recipients among their employees."

In a publicpost, Facebook CEO Mark Zuckerberg said about Trump's announcement: "This is a sad day for our country" and that he and his immigration advocacy vehicle at Fwd.US will be "doing even more in the weeks ahead to make sure Dreamers have the protections they deserve."

Sundar Pichai, the CEO of Google (an arm of Alphabet), did not make quite the same commitment on Twitter. But he took a moral stand, writing, "Dreamers are our neighbors, our friends and our co-workers. This is their home. Congress needs to act now to#DefendDACA.#WithDreamers."

When President Trump was first elected, leaders in the tech industry were reluctant to criticize campaign pledges of his that went against their values and interests. They took a wait-and-see approach and grappled with how to be a successful multinational in an increasingly nationalistic world. Tuesday morning's outpouring illustrates a clear shift in business leaders' willingness to speak out against decisions by the administration.
