Nigerian President Bola Ahmed Tinubu has asked a U.S. federal court to block the release of records held by American law enforcement agencies concerning historical investigations involving him, according to court documents and his lawyers.

Tinubu’s legal team, comprising Christopher W. Carmichael, Victor P. Henderson and Oluwole O. Afolabi, argued that the records should remain withheld or redacted.

In a 16-page filing with the U.S. District Court for the District of Columbia, the lawyers opposed a request by American transparency activist Aaron Greenspan to obtain records held by the U.S. Department of Justice, the Federal Bureau of Investigation and the Drug Enforcement Administration.

Greenspan filed a Freedom of Information Act lawsuit against several U.S. government agencies in 2023, seeking records related to historical investigations involving Tinubu.

Among the documents sought are the FBI’s entire file on Tinubu and FBI Form 302 interview records concerning the period between 1992 and 1993.
