A group of 34 members of Congress is pressing the Department of Homeland Security for a detailed technical accounting of its data infrastructure, specifically targeting systems built by Palantir Technologies. In a letter obtained by WIRED, legislators instructed DHS and Immigration and Customs Enforcement to disclose the architecture of Palantir platforms and their integration with tools from Clearview AI, PenLink, L3Harris, and Paragon Solutions.

The request functions as a demand for a system design review. Lawmakers asked which government and commercial datasets feed into Palantir's platforms and requested a comprehensive report on a specific Palantir application, 'ELITE' (Enhanced Leads Identification and Targeting for Enforcement). They seek documentation on its development, data categorization schemas, and the exact number of authorized users within DHS.

From an engineering perspective, the letter questions the data governance and retention policies governing these aggregated systems. It explicitly asks about the 'legal authorities' and internal policies that define data use and lifespan, expressing concern that the suite operates as a mass surveillance ecosystem. The technical focus underscores Palantir's entrenched position; the company built ICE's core law enforcement case management system and the Immigration Lifecycle Operating System, which agents use to select and track deportation cases.

Palantir's government contract revenue reached approximately $1 billion in the 2025 fiscal year, a sharp increase. The congressional group, led by Democrat Dan Goldman, has set a deadline of April 24 for DHS and ICE to respond with the requested technical and policy documentation.
