Category: Trump Administration Official
Role: Deputy Secretary of Defense (confirmed March 14, 2025); Co-Founder and former CEO of Cerberus Capital Management, a $65 billion private equity firm with substantial defense industry holdings
Priority: P1 (Senior cabinet-level official with documented financial conflicts in the department he oversees)

Documented Conflicts of Interest

Cerberus Defense Holdings vs. Pentagon Contracting

Senator Elizabeth Warren formally called on Feinberg to “completely cut” his ties to Cerberus upon confirmation, arguing that “stepping down from CEO” was insufficient given his co-founder status and ongoing financial interests. The Senator’s formal correspondence noted that his “ongoing relationship with Cerberus creates at least a perception of a conflict of interest that could undermine confidence in the fairness of the contracting process.”

An ethics lawyer who worked in the Bush administration, quoted in Warren’s correspondence, agreed that the financial ties were problematic even after his CEO departure.

Specific conflict — Golden Dome missile defense contracts: Senator Warren subsequently sent a formal letter to Feinberg specifically regarding his role in Golden Dome contracting decisions — a major Pentagon missile defense initiative — given Cerberus’s defense industry portfolio. The letter raised concerns that companies in the Cerberus portfolio may be positioned to benefit from Golden Dome contracts that Feinberg has authority to influence.

DoD Contracting Under His Authority

Several companies in which Cerberus holds or held positions have existing or pending Pentagon contracts:

• Navistar Defense — automotive/defense manufacturer with existing DoD supply relationships; paid $50M settlement on fraud allegations
• TransDigm — sole-source defense parts supplier under repeated DoD IG scrutiny for price gouging
• Defense sector exposure through multiple portfolio company subsidiaries

Epstein Files Financial Ties

The Project on Government Oversight (POGO) reported that Epstein-related files disclosed financial connections between Feinberg and individuals in Jeffrey Epstein’s network. Feinberg has already faced scrutiny over Cerberus business practices separate from the Epstein disclosure. The nature and materiality of these connections has not been fully adjudicated in public reporting.

Pattern Analysis

Feinberg’s appointment follows a pattern in the Trump second administration of appointing private equity executives to agency leadership positions where their firms have direct financial stakes in agency outcomes. In Feinberg’s case, the conflict is particularly acute because:

1. Defense procurement is the core function of the office he holds. Unlike appointments in regulatory agencies where the official oversees policy from a distance, Feinberg directly participates in procurement decisions — the exact commercial activity where Cerberus has business.

1. The scale of Cerberus’s defense exposure is substantial. A $65B fund with material defense industry positions creates hundreds of millions in potential conflict surface. Navistar Defense’s history of DoD fraud allegations adds a retaliatory or favoritism dynamic to any procurement decisions affecting the company.

1. “Stepping down as CEO” did not sever financial interests. As co-founder, Feinberg retains economic interests in Cerberus funds through carried interest, GP stakes, and other structural mechanisms that typically survive a CEO title change. The critical question — whether he divested his economic interests in funds holding defense assets — has not been publicly confirmed.

1. Suppression of investigative oversight. The Revolving Door Project and multiple advocacy organizations have flagged Feinberg’s appointment as a model case of the revolving door between private finance and military-industrial contracting. Congressional oversight is limited by the Republican majority’s unwillingness to pursue investigations into administration officials’ conflicts.

Severity Assessment

Financial scale: $65B fund with defense portfolio; potential hundreds of millions in indirect benefit from contracting decisions
Institutional harm: The Deputy Secretary of Defense influences the largest procurement operation in the U.S. government; conflicts here affect national security contracting integrity
Democratic erosion: The appointment of a private equity billionaire with undivested defense industry positions to the Pentagon’s #2 role normalizes the conversion of government power into private financial opportunity at the highest institutional level

Accountability Status

Current status: Confirmed Deputy Secretary of Defense (March 14, 2025). Active.
Legal exposure: No criminal charges. Under scrutiny from Senate oversight (Warren) for conflicts; Epstein-adjacent financial disclosures under informal review.
Ethics disclosure status: Whether Feinberg filed recusal agreements, conflict waivers, or divestiture commitments beyond stepping down as CEO has not been confirmed in public reporting as of May 2026.

For Trump Supporters: Questions Worth Considering

Steve Feinberg co-founded a $65 billion private equity firm with significant defense industry holdings. He was confirmed as the Pentagon’s second-ranking official — the person who oversees military procurement — in March 2025. His own Senate confirmation drew objections from a former Bush administration ethics lawyer, not just Democrats, over the conflict of interest his Cerberus holdings create.

Here is the core question: If you believe in fiscal responsibility and that defense dollars should go to the best-qualified contractors at fair prices — not to companies with political connections — does it concern you that the person making those procurement decisions has financial stakes in some of those contractors?

Defense procurement fraud is a bipartisan concern. Navistar Defense — a company in Feinberg’s portfolio — paid $50 million to settle fraud allegations against the Marine Corps. TransDigm — another portfolio name — has faced repeated DoD Inspector General findings of excess pricing. The Inspector General exists precisely to catch this kind of problem. The question is whether an Inspector General can function when the Deputy Secretary who oversees contracting has financial interests in the contractors being reviewed.

You don’t have to agree with Democratic senators to recognize that principle. It’s the same standard conservatives applied to every Democratic cabinet official who left Wall Street for Washington.
