Wyden, Goldman, Velázquez Letter to Palantir CEO Karp Demands Answers on ICE Surveillance Tools

Opening

On June 17, 2025, Sen. Ron Wyden (D-OR), Rep. Daniel Goldman (D-NY), and Rep. Nydia Velázquez (D-NY) — joined by approximately 30 lawmakers — sent a letter to Palantir Technologies CEO Alex Karp demanding detailed answers on Palantir’s role in Trump-administration ICE surveillance tools, including the ELITE (Enhanced Leads Identification & Targeting for Enforcement) platform that fuses HHS Medicaid data into ICE deportation targeting and the ImmigrationOS mega-database announced as a $30M Palantir contract in early June 2025.

What Happened

The letter — issued on Senate Finance Committee letterhead with Wyden as lead signatory in his capacity as committee ranking member — requested specific information about:

1. The full scope of Palantir’s ICE contracts and the data sources being integrated into ImmigrationOS (specifically: IRS, SSA, passport, and license-plate data integration).
2. Whether Palantir’s ELITE tool is using Medicaid enrollee data routed through the CMS-ICE data-sharing agreement disclosed in mid-July 2025 reporting (the agreement covers 79 million enrollees’ personal data including names, addresses, birth dates, ethnic and racial information, and Social Security numbers).
3. Palantir’s compliance posture with respect to the Privacy Act, the 2024 PCLOB recommendations on commercial data brokers, and Section 7 of the Anti-Deficiency Act.
4. The specific role of former Palantir personnel inside HHS (the Clark Minor pivot to HHS CTO/CIO documented in February 2025) in the data-architecture decisions enabling the CMS-ICE data flow.
5. Whether Palantir has disclosed its ICE work to its institutional shareholders and to its public-company investors per SEC disclosure obligations.

The letter set a 30-day response deadline and was promptly published in full by the Senate Finance Committee.

Why This Event Matters

The Wyden-Goldman-Velázquez letter is the first major congressional oversight pressure on the Trump-2 Palantir-ICE architecture and the inflection point where the Palantir ImmigrationOS / ELITE / SHARE-BPA / Medicaid-data-fusion architecture moved from quiet intra-agency operation into the publicly contested oversight surface.

Three structural significances:

1. Karp did not respond. Wyden has stated publicly he did not receive a substantive response from Palantir. The non-response is itself the operational signature: a tier-1 administration vendor declining to answer a ranking-member committee letter on a multi-billion-dollar federal contract footprint.

2. The letter’s specific factual demands document the integrated architecture. By naming ELITE, ImmigrationOS, the IRS / SSA / passport / license-plate fusion, and the Medicaid-data-sharing pathway in a single document, the letter publicly mapped the cluster pattern that the hhs-palantir-cluster theme later analyzes. The letter is a structural-claim primary source — it documents that congressional Democratic leadership had already integrated the cross-agency Palantir data-fusion architecture into a single oversight frame by June 2025.

3. The letter precedes — and predicts — the EFF January 15, 2026 ELITE exposure. Seven months before EFF publicly mapped the ELITE → Medicaid → ICE deportation-targeting pipeline in 2026-02-19–ice-covert-suburban-tactics-palantir-elite-surveillance, the Wyden letter had named the same data-flow architecture. The temporal sequence (June 2025 letter → September 2025 ELITE deployment → January 2026 EFF exposure) shows that congressional oversight had the architecture in view before the public-disclosure event.

Broader Context

The letter sits inside the trump-2-surveillance-procurement-chronology-2025-2026 June 2025 cluster — alongside the Founders Fund $1B Anduril Series G check (June 5), the Anthropic Claude FedRAMP High GovCloud authorization (June 26), and the Palantir $30M ImmigrationOS contract (early June). The letter is the oversight-pressure event of the chronology’s most-consequential month.

The Karp-Wyden letter is referenced repeatedly in subsequent reporting — particularly the April 2026 Bloomberg Government coverage of Patel-firing-as-FISA-702-bargaining-chip (2026-04-28–bloomberg-government-fire-patel-fisa-reauth-bargaining-chip) and the ProPublica April 23, 2026 finding of 144 Trump-2 appointees disclosing Palantir holdings (2026-04-23–144-trump-appointees-palantir-disclosures). It is the predicate event for the spring 2026 oversight pressure trajectory.

Research Gaps

• Palantir formal response (or formal non-response): Did Palantir send any letter, even a refusal-to-answer, to the Senate Finance Committee within or beyond the 30-day deadline? Has Karp commented publicly on the letter’s factual claims?
• Subsequent letters / hearings: Did Wyden, Goldman, or Velázquez follow with additional letters, hearing requests, or subpoenas? The trajectory of the oversight pressure post-June 2025 is the next research layer.
• Palantir 10-Q / 10-K disclosure pattern: Has Palantir’s SEC filing disclosed the contract footprint or oversight-pressure context that the letter raised? The disclosure-pattern over Q3-Q4 2025 and Q1 2026 is research-gap.
• The full list of ~30 lawmaker co-signatories: The Senate Finance press release lists the lead signatories; the full co-signatory list deserves separate research.
