Salesforce employees circulated an internal letter to the chief executive Marc Benioff called upon him to criticize recent actions by US Immigration and Customs Enforcementban the use of Salesforce software by immigration agents, and roll back federal legislation that would dramatically reform the agency.

The letter specifically cited the “recent murders of Renee Good and Alex Pretti in Minneapolis” as factors, calling them “a damning indictment of a system that rejects human decency.” It is unclear how many signatories to the letter have been received so far.

The letter, which has not been previously reported, was organized amid Salesforce’s annual leadership event this week in Las Vegas. During an appearance at the event earlier today, Benioff asked international employees to stand up to thank them for attending. He then joked that ICE agents were in the building monitoring them, according to current and former Salesforce employees who spoke to WIRED.

Benioff’s comments sparked an immediate backlash among employees. “A lot of people are angry,” said one source, who asked not to be identified for fear of retaliation. Another source told WIRED that the internal pushback is stronger now than it was after Benioff made other controversial comments last fall supporting President Trump’s call to deploy the National Guard to San Francisco to address crime.

Salesforce did not immediately respond to a request for comment from WIRED. Business Insider and 404 Media previously reported on Benioff’s comments and the reaction to them within Salesforce.

“We are deeply concerned by leaked documentation that reveals Salesforce is deploying AI technology to US Immigration and Customs Enforcement to help the agency ‘quickly’ hire 10,000 new agents and vet tip line reports,” the letter read. “Giving ‘Agentforce’ the infrastructure to scale a mass deportation agenda that currently detains 66,000 people—73 percent without a criminal record—represents a fundamental betrayal of our commitment to the ethical use of technology.”

The letter argues that Benioff’s voice “carries extraordinary weight in Washington,” pointing to an episode last fall when Trump halted an ICE deployment to San Francisco after what appeared to be outreach from Bay Area technology leaders, including Benioff and Nvidia CEO Jensen Huang. It urged Benioff to use that influence as a “corporate statesman” to issue a public statement condemning what it called ICE’s unconstitutional conduct and to commit Salesforce to clear “red lines” that prohibit the use of its cloud and AI products for state violence.

Benioff has weighed in on national and local political issues over the years. He supported Democratic presidential candidate Hillary Clinton in 2016 and later became one of the highest profile supporters of Proposition Ca failed San Francisco ballot measure that would have raised taxes to fund programs to address homelessness. In 2020, he will Donate to primary campaigns of several Democratic presidential candidates, including Kamala Harris.

But since Trump returned to the White House in January, Benioff has signaled greater support for some Republican leaders. In an interview, he said that he tries to remain non-partisan because he also owns Time magazine. But he also joked that, while he refused to contribute directly to Trump’s inauguration fund, he “donated” a photo of the president on the cover of the magazine, which named him 2024 Person of the Year. “He can use the cover of Time magazine for free,” Benioff said in an interview with Fortune.

Benioff also faced backlash from Salesforce employees last fall when he proposed the National Guard must be sent to San Francisco to solve the crime before the company’s annual conference in the city. He later apologized for the comments, explaining that they stemmed from genuine concerns about safety. He later reversed his stance and joined Nvidia’s Huang in asking Trump to refrain from sending troops.
