FWD.us was formed by Zuckerberg, Bill Gates and other tech heavyweights in 2013 to help fix the immigration system.
According to a report by FWD.us, 91 percent of DACA recipients are employed. Canceling the program, which shields those immigrants from deportation, would mean roughly 30,000 a month would lose their work permits as their DACA status expires, the report said.
On Friday, House Speaker Paul Ryan, R-Wisconsin, and Sen. Orrin Hatch, R-Utah, pushed Trump not to end the program. In an open letter Thursday, nearly 400 executives, including Zuckerberg and Amazon's Jeff Bezos, urged Trump to retain the protections.
Trump is under pressure from attorney generals from 10 states, including Texas, to end the program by September 5.
"The fact that he is being threatened by the Attorney General of Texas, with everything that's going on in Texas, that we're going to spend taxpayer dollars threatening to sue to overturn DACA so they can restart the deportations of 800,000 dreamers, that is just absolutely wrong," Schulte said.
So far, the president has "done the right thing," he added, pointing out that about 200,000 people have gone through the program under Trump.
"He can continue to do the right thing by keeping this program in place and calling on Congress to pass the Dream Act," which would protect those immigrants.
