A fresh dispute has emerged over the United States court proceedings involving records connected to President Bola Ahmed Tinubu, after a US-based political advisory and lobbying firm accused the Nigerian Presidency of giving the public a misleading account of the litigation.
The controversy follows a September 3 statement by the Presidency insisting that the matter before the United States District Court for the District of Columbia is a civil Freedom of Information Act (FOIA) records-disclosure dispute, rather than a criminal prosecution of President Tinubu.
The lobbying firm, Von Batten-Montague-York, subsequently said it was preparing to ask the Washington court for permission to participate as an amicus curiae—a third party seeking to provide information or arguments relevant to the court’s consideration of a case.
What triggered the latest dispute?
The immediate disagreement followed the Presidency’s clarification of the case on Thursday.
Special Adviser to the President on Information and Strategy, Bayo Onanuga, said the litigation arose from FOIA requests submitted by Aaron Greenspan to US government agencies beginning in 2022. According to the Presidency, the case does not constitute a criminal trial, criminal charge or judicial finding that Tinubu committed a crime.
The Presidency also said the Federal Bureau of Investigation (FBI) and Drug Enforcement Administration (DEA) had produced hundreds of pages of records, with portions withheld or redacted under various legal protections.
Von Batten-Montague-York challenged the Presidency’s characterization of the underlying records and said its founder was preparing an application concerning the President’s asserted privacy interests under FOIA Exemption 7(C).
The firm argued that once the Nigerian government itself publicly discusses the records and the privacy issue, the weight attached to the President’s privacy claim could become an issue before the court.
Those are the firm’s legal and political arguments, however, and they should not be confused with a judicial determination that the Presidency made false statements or that Tinubu committed a drug-related offence.
The important distinction: a records case is not a criminal trial
One of the most important points for readers following the controversy is the difference between a FOIA lawsuit and a criminal prosecution.
FOIA litigation generally concerns whether government agencies must release records requested by members of the public and whether statutory exemptions permit the government to withhold or redact particular information.
That is materially different from a criminal case, in which prosecutors charge an individual with an offence and a court determines criminal liability.
The US District Court’s earlier ruling in the Greenspan litigation confirms that the case concerns FOIA requests for investigative records. The court’s April 8, 2025 opinion identified the FBI, DEA and CIA requests concerning Tinubu and described the underlying material as relating to a broader investigation into a Chicago-area heroin trafficking and money-laundering operation in the early 1990s.
Crucially, the court did not find Tinubu guilty of drug trafficking.
What has the US court actually ruled?
The court’s 2025 ruling is significant because it provides a clearer picture of how the dispute developed.
Greenspan filed multiple FOIA requests between 2022 and 2023 seeking records from several US agencies, including the FBI, DEA and CIA. Some agencies initially issued what is known as a “Glomar response”, meaning they would neither confirm nor deny whether responsive records existed.
The agencies relied, among other things, on privacy protections under FOIA.
Judge Beryl Howell later reached different conclusions concerning the agencies.
The court ruled that the FBI and DEA could no longer rely on their Glomar responses concerning the existence of an investigation involving Tinubu. The judge found that information in publicly filed government court documents amounted to an official acknowledgment of Tinubu’s connection to the investigation for purposes of the FOIA dispute.
The court therefore ordered the FBI and DEA to process non-exempt records responsive to the relevant requests.
The CIA, however, received a different ruling. The court upheld the CIA’s Glomar response because the publicly available material cited by Greenspan did not specifically establish that the CIA possessed records concerning Tinubu.
That distinction is important: the court’s ruling dealt with disclosure rules and agency responses under FOIA, not a finding of criminal guilt.
Why Tinubu became involved in the lawsuit
President Tinubu was subsequently permitted to intervene in the proceedings.
The court record shows that Tinubu sought to participate because of privacy interests concerning potentially confidential tax and federal law-enforcement records. His motion to intervene was granted in November 2023.
That means the President is not simply an outside subject mentioned in a FOIA request. He has been allowed to participate in the litigation to protect interests he says could be affected by disclosure.
This is also why the question of privacy has become central to the latest confrontation between the Presidency and the lobbying firm.
What is at the centre of the allegations?
The historical records being sought relate to a US investigation into a Chicago-area heroin trafficking and money-laundering operation during the late 1980s and early 1990s.
The 2025 court opinion records that Greenspan’s FOIA requests sought investigative material involving Tinubu and other individuals allegedly connected to that investigation.
The opinion also discusses a publicly filed IRS special-agent affidavit that formed part of a US civil forfeiture complaint. According to the court, the affidavit described information gathered during an investigation involving the FBI, DEA and IRS and included allegations concerning financial accounts associated with Tinubu.
These historical allegations are the source of much of the current political controversy.
However, the existence of investigative records, allegations contained in an affidavit or a FOIA dispute does not by itself establish that the person named in those records committed a criminal offence.
That distinction is particularly important as political actors on both sides use the litigation to advance competing narratives.
The Presidency’s latest position
The Nigerian government has sought to put the legal controversy in context.
Onanuga said the case originated with Greenspan’s FOIA requests and maintained that the litigation should not be portrayed as a criminal proceeding against Tinubu.
The Presidency also pointed to a February 4, 2003 letter from the American Consulate in Lagos which, according to the government, stated that an FBI records check had found no criminal arrest records, wants or warrants for Tinubu at that time.
The government has further argued that the remaining dispute concerns the legality of redactions and withholding of records already processed by US agencies.
What the US firm is now seeking
Von Batten-Montague-York says it intends to seek permission from the US District Court to submit an amicus curiae brief.
According to the firm’s public statement, it notified Greenspan, the US Department of Justice and Tinubu’s legal representatives before pursuing the proposed filing.
Its central argument is that the Presidency’s own public discussion of the litigation and privacy claims could become relevant when the court weighs the President’s asserted privacy interests under FOIA.
Whether the court permits such a filing—and, if permitted, what weight it gives the firm’s arguments—remains for the judge to determine.
The firm’s accusation that the Presidency is “misleading the world” is therefore an allegation made by the firm, not a finding by the US court.
A timeline of the Tinubu FOIA controversy
2022: Aaron Greenspan begins submitting FOIA requests to US federal agencies seeking records concerning Tinubu and historical investigations.
June 2023: Greenspan files Civil Action No. 23-1816 in the US District Court for the District of Columbia after disputes over agency responses to his FOIA requests.
November 2023: Tinubu is permitted to intervene in the case to protect his asserted privacy interests.
April 2025: Judge Beryl Howell rules that the FBI and DEA cannot maintain their Glomar responses concerning the existence of an investigation involving Tinubu, while the CIA’s Glomar response remains protected.
August 2026: Tinubu’s legal team challenges further disclosure of records and seeks continued protection for information it argues is covered by privacy and other legal protections. Contemporary reporting says the FBI and DEA have produced records with redactions.
September 3, 2026: The Presidency publicly stresses that the Washington litigation is a civil FOIA dispute rather than a criminal case against Tinubu.
September 4, 2026: Von Batten-Montague-York responds by announcing plans to seek permission to file an amicus brief and argues that the Presidency’s public statements could affect the privacy question before the court.
Why the latest development matters
The dispute matters beyond the political exchanges because the underlying court proceedings could determine how much additional information about a decades-old US investigation becomes publicly available.
It also places two competing interests against each other.
On one side is the public interest in understanding what US law-enforcement agencies investigated and what information government records contain. On the other is the legal protection given to personal information, confidential investigative material, sources, investigative techniques and other categories of records protected under FOIA.
The 2025 court ruling already established that the FBI and DEA could not simply refuse to acknowledge the existence of an investigation involving Tinubu by relying on a Glomar response. But that does not mean every document in an investigative file must automatically be released. The court specifically distinguished between acknowledging the existence of an investigation and protecting the contents of investigative records through lawful exemptions, redactions or withholdings.
That distinction is likely to remain central as the litigation continues.
What readers should watch next
The immediate questions are whether Von Batten-Montague-York will formally seek leave to file its proposed amicus brief, whether the court accepts the filing and how the judge treats the competing arguments over privacy and public disclosure.
The next substantive developments should come from the US District Court for the District of Columbia and the parties’ court filings, rather than political statements alone.
For now, the most accurate description of the matter is that it is an ongoing civil FOIA dispute involving access to US government records relating to historical investigations. It should not be reported as a criminal conviction or as proof that President Tinubu has been found guilty of heroin trafficking.
The latest clash is instead another chapter in a legal and political battle over what the US government records reveal, what can legally be disclosed and how much privacy protection President Tinubu can claim over those records.
