Fifteen activists were taken into custody Monday night after staging a sit‑in at the Chelsea offices of Palantir Technologies, one of the nation’s most high‑profile tech companies, following a politically charged Passover rally in Union Square that featured New York City Mayor Zohran Mamdani. The arrests marked a dramatic escalation in public protests over immigration enforcement, corporate data contracts and the role of local leadership in national political debates.
The evening began in Manhattan’s Union Square, where hundreds of people gathered for a protest dubbed “Seder in the Streets.” Organized by Jews for Racial & Economic Justice, the event combined traditional Passover themes with sharp criticism of current federal immigration policies, particularly those enacted by U.S. Immigration and Customs Enforcement (ICE). Attendees recited prayers, sang songs and listened to personal stories from people with family members in ICE detention centers, drawing on the biblical Exodus narrative to frame their activism.
Mayor Zohran Mamdani, who has become known for his outspoken stance on immigration enforcement and civil rights, addressed the crowd, urging solidarity and linking the ancient Jewish story of liberation with contemporary struggles against deportation and detention. “The lessons of hope overcoming fear, of solidarity being able to overcome isolation, and the knowledge that at the end of the story, freedom is attained,” Mamdani said to supporters.
Following the Union Square gathering, a group of demonstrators marched a short distance to the offices of Palantir Technologies Inc. in Chelsea. Palantir, a data analytics firm known for its work with government agencies, has faced sustained criticism from civil liberties groups and immigrant‑rights activists for contracts that provide software used by ICE to identify and track individuals for deportation.
As protesters entered the lobby of the Palantir building and refused to disperse, law enforcement officers moved in. According to New York Police Department officials, 15 people were arrested after refusing police orders to leave the premises. Those detained were issued court summonses and are expected to be released. The NYPD did not immediately release details on charges, but the arrests appeared to center on trespassing and refusing to comply with police directives.
Outside the building, hundreds more demonstrators chanted and held banners that tied together tech criticism and immigration policy, including one referencing the Passover story: “ICE kidnaps, Palantir profits. Let our people go.” The imagery underscored the protest’s fusion of religious symbolism with modern political advocacy.
Palantir, co‑founded by tech investor Peter Thiel, has long been at the center of controversy for its role in providing law enforcement and immigration agencies with powerful data tools. Critics argue these tools enable surveillance and enforcement practices that disproportionately affect immigrant communities and erode privacy rights. Supporters, however, contend that the software enhances law enforcement capabilities and contributes to national security objectives.
The escalation to arrests highlights the rising tensions in New York City over immigration policy and corporate responsibility. In recent months, federal enforcement activity by ICE in the city has increased, drawing sharp backlash from immigrant advocates and local politicians. Demonstrators at Union Square and the subsequent sit‑in expressed frustration with what many see as a lack of meaningful local pushback against deportations and harsh enforcement tactics.
City officials, including New York City Comptroller Mark Levine, have also raised concerns about Palantir’s involvement with ICE, seeking more transparency and oversight of the company’s contracts with federal agencies. Levine sent a letter to Palantir requesting an independent human‑rights risk assessment of its work for the Department of Homeland Security, reflecting growing unease within city government over the ethical implications of such partnerships.
The activism surrounding the Palantir protest is part of a broader movement that has demanded legislative reforms, including passage of the New York for All Act. Advocates say this proposal — which has stalled in the state legislature — would limit how much state and local agencies cooperate with federal immigration enforcement, giving cities like New York more power to protect undocumented residents.
The choice to stage the sit‑in on the sixth night of Passover was intentional, tying the protest’s themes of liberation and resistance directly to the holiday’s narrative. Organizers said the Exodus story — in which Moses leads the Israelites out of slavery — provides a powerful metaphor for confronting modern systems of injustice and detention.
Mayoral involvement in such protests places increased focus on Mayor Mamdani’s approach to immigration issues. Since taking office, he has been vocal in his support for immigrant communities and critical of what he describes as overly aggressive enforcement practices by federal agencies. His participation at Union Square signals a willingness to align himself publicly with activist movements, even as such actions draw both praise and criticism.
Critics of the protest argue that actions like the Chelsea sit‑in — particularly those that result in arrests — risk alienating moderate supporters and raise questions about the legality of occupying private property to make political points. Supporters counter that civil disobedience has a long history in social justice movements and is necessary when institutional channels fail to address urgent human rights concerns.
As the legal aftermath of Monday’s sit‑in unfolds, activists and officials alike are likely to watch closely. The event underscores the growing friction in American cities over immigration, technology, and civic protest — a friction that reflects broader national debates about the role of local leadership in confronting federal policies many view as unjust. The intersection of holiday symbolism, political activism, and direct action captures a moment in New York City where religious heritage and contemporary protest converge with forceful public engagement
