State Dept OIG Refers Witkoff/Sacks UAE Ethics Probe Request to Office of Investigations; Senators Press for Full Investigation

Opening Paragraph

On December 12, 2025 (publicly confirmed via Semafor reporting dated December 22, 2025), the State Department Office of Inspector General responded to the September 23, 2025 Warren/Slotkin probe request by referring the matter to its Office of Investigations for review. Senators Warren and Slotkin responded by publicly pressing for a “full and robust investigation,” releasing statements characterizing the referral as insufficient without a formal investigation commitment.

What Happened / Key Facts

The State Department OIG’s December 12, 2025 letter to the senators described the following disposition:

• The IG confirmed it was evaluating the request and referred it to the Office of Investigations for review
• The letter did not commit to any investigation — Semafor characterized it as appearing to be “a standard response”
• An IG representative declined further comment, stating the office does not discuss “investigative matters”
• The White House stated officials “followed ethics rules”

Precision on the referral: “Referred to the Office of Investigations for review” is a step beyond generic evaluation — it routes the request to the investigative arm of the OIG rather than treating it as administratively closed. However, referral for review is not the same as opening a formal investigation. No investigators were publicly assigned, no subpoenas or document requests were confirmed, and no investigation opening was announced.

Senators Warren and Slotkin responded publicly on December 22, 2025:

• Warren: “The Inspector General has a role to address this matter and conduct a review.”
• Slotkin: “America’s foreign policy decisions must be made solely on the basis of American national interest.”

Both senators called for a “full and robust investigation.”

Why This Event Matters

The December 12, 2025 letter represents the last confirmed public action by the State Department OIG in this matter as of June 23, 2026. No tier-1 source has confirmed that a formal OIG investigation was subsequently opened or that the probe was declined. Silence from an IG office confirms neither outcome — IGs have discretion to open, narrow, or decline probes without announcement. The referral to the Office of Investigations is meaningful as a procedural step (it moved the request out of administrative intake), but it does not establish that an investigation began.

Structural independence concern: The Acting IG (Arne Baker) was installed after Trump fired 17 inspectors general in January 2025. A federal judge found the firings unlawful but declined to reinstate dismissed IGs. The independence of an Acting IG serving at the administration’s pleasure, evaluating conduct by administration officials, is a material structural concern documented by watchdog groups including American Oversight and CREW.

Broader Context

The December 22, 2025 public confirmation came approximately 90 days after the initial September 23, 2025 probe request. Between September and December 2025, Senator Schiff and seven additional Senate Democrats had separately pressed Witkoff on his failure to divest from World Liberty Financial (October 22, 2025), and Warren/Murphy had issued their own continuation of an ethics investigation (November 18, 2025). The OIG response thus came in the context of multi-track congressional pressure that was already escalating.

Research Gaps

• Whether the State Dept OIG subsequently opened a formal investigation or issued a declination — blocked: OIG offices do not publicly announce investigation openings or declinations
• Whether Commerce OIG or OGE responded separately to the same September 23, 2025 letter
• Whether the OIG’s referral to “Office of Investigations” triggered any document preservation order to State Department records holders
