The US Drug Enforcement Administration (DEA) defends its decision to withhold some investigative records connected to an inquiry involving Nigerian President Bola Tinubu. In a court filing submitted in Washington, DC on September 23, 2026, the US government says it has redacted parts of the files rather than fully disclose them.

The DEA argues that releasing the withheld material would jeopardize confidential sources and sensitive investigative methods, including information contained in specific reports cited in the filing. It also cites legal protections under US law for keeping such information private, saying those safeguards outweigh the public interest in disclosure. The filing is tied to a Freedom of Information Act (FOIA) request.

According to one report, the FOIA requester, activist Aaron Greenspan, seeks access to historic US agency records alleged to be linked to Tinubu and others. The outlets describe the withheld content as operational documents that include details about investigations and confidential informants, and they characterize the filing as the DEA’s formal justification for refusing to release portions of the records.
