“When a few prosecutors finally began targeting BCCI’s operations in the late Eighties, President George Herbert Walker Bush boldly moved in with a federal probe directed by Justice Department investigator Robert Mueller. The U.S. Senate later found that the probe had been unaccountably ‘botched’–witnesses went missing, CIA records got ‘lost,’… Lower-ranking prosecutors told of heavy pressure from on high to ‘lay off.’ Most of the big BCCI players went unpunished or, like [Khalib bin] Mahfouz, got off with wrist-slap fines and sanctions. Mueller, of course, wound up as head of the FBI, appointed to the post in July 2001–by George W. Bush.”

Or did it deal with the Pan Am bombing which ties back into Libya.

With the Pan Am 103 case, Mueller was covering up facts related to some of the of victims of the bombing—a group of U.S. intelligence specialists led by Major Charles McKee of the Defense Intelligence Agency. McKee had gone to Beirut to find and rescue hostages and, while there, learned about CIA involvement in a drug smuggling operation run through an agency project called COREA. As TIME magazine reported, the likely explanation for the bombing, supported by independent intelligence experts, was that U.S. operatives “targeted Flight 103 in order to kill the hostage-rescue team.” This would prevent disclosure of what McKee’s team had learned. That theory was also supported by the fact that the CIA showed up immediately at the scene of the crash, took McKee’s briefcase, and returned it empty.
