U.S. Court orders release of files in Tinubu-linked drug probe

A high-profile Freedom of Information Act (FOIA) case seeking U.S. federal records tied to a 1990s narcotics investigation in Chicago, in which Nigerian President Bola Ahmed Tinubu has been named in court filings and historical documents, is moving toward a major disclosure deadline set for June 1, 2026.

The case, which has drawn sustained legal and public attention, centers on long-requested records from the Federal Bureau of Investigation (FBI) and the Drug Enforcement Administration (DEA) concerning a decades-old investigation that allegedly involved individuals linked to alleged narcotics trafficking activity in Chicago during the early 1990s.

FOIA Requests Spark Multi-Year Legal Battle

The litigation began after transparency advocate Aaron Greenspan, founder of the legal data platform PlainSite, submitted FOIA requests in 2022 to multiple U.S. agencies, including the FBI, DEA, Internal Revenue Service (IRS), State Department, Central Intelligence Agency (CIA), and the Executive Office of U.S. Attorneys.

The requests sought records connected to the Chicago investigation and related proceedings. Investigative journalist David Hundeyin was reported to have provided assistance in the broader research effort.

When agencies declined to release the requested documents, Greenspan filed a civil lawsuit in 2023, escalating the matter into federal court.

Government Agencies Cited Delays and Exemptions

Court filings show that over several years, the FBI and DEA provided shifting timelines for completion of searches and production of documents, at various times projecting responses stretching from 2025 into early 2026.

Both agencies also invoked so-called “Glomar responses,” a legal mechanism allowing them to neither confirm nor deny the existence of certain records.

According to filings, the agencies also cited consultation requirements with other federal bodies as reasons for continued delays, but did not produce substantive records during that period.

Judge Orders Accelerated Disclosure

In a ruling issued on February 3, 2026, U.S. District Judge Beryl A. Howell of the District of Columbia rejected several of the agencies’ legal arguments, including their use of Glomar responses, which she described as not sufficiently justified under the circumstances presented in court.

Judge Howell ordered the FBI and DEA to proceed with structured disclosure of non-exempt materials and directed the DEA to produce a detailed Vaughn index explaining redactions or withheld content.

The court also set a firm deadline of June 1, 2026, for full compliance with the disclosure order and required interim status reporting ahead of that date

Nature of the Underlying Records

The case relates to historical investigative materials from the early 1990s, during which U.S. federal authorities reportedly conducted inquiries in Chicago involving alleged narcotics-related financial activity.

Publicly available historical records and prior affidavits, including those attributed to former IRS Special Agent Kevin Moss, have been cited in discussions of civil forfeiture proceedings involving approximately $460,000, which authorities at the time alleged were connected to drug trafficking proceeds. No criminal conviction of the Nigerian leader has been recorded in connection with those proceedings.

Large portions of FBI investigative files—estimated in court submissions to run into thousands of pages—remain unreleased and are now subject to the court-ordered disclosure process.

Political and Legal Sensitivities

The Nigerian government has previously stated that publicly circulated documents from the period do not constitute evidence of wrongdoing and that the matter has been mischaracterized in some public commentary.

Legal representatives involved in the FOIA litigation argue that only full disclosure of the complete investigative record will clarify the historical context of the case.

The court has not made any finding of criminal liability regarding any individual named in the records, and the proceedings remain focused strictly on document disclosure under U.S. transparency laws.

Wider Context of FOIA Transparency Disputes

The case has unfolded against a broader backdrop of U.S. legal disputes over the release of sensitive investigative materials, including recent high-profile document disclosures in unrelated cases involving deceased financier Jeffrey Epstein.

Legal observers note that federal courts have increasingly scrutinized agency reliance on blanket exemptions where public interest arguments are raised, particularly in cases involving historical investigations.

With the June 1, 2026 deadline approaching, the FBI and DEA are required to complete staged disclosures and provide detailed justifications for any remaining redactions.

A final joint status report is expected in early May 2026, which will determine whether the agencies are on track to comply fully with the court’s order.
