CIA inspector general John Helgerson, who is investigating some aspects of the CIA’s performance before 9/11, recuses himself from part of the investigation concerning alleged 9/11 mastermind Khalid Shaikh Mohammed (KSM). According to the report’s executive summary, the reason for the recusal is a “conflict of interest,” although the precise nature of this conflict is unknown. This part of the investigation is handled by two deputy inspectors general. [Central Intelligence Agency, 6/2005, pp. xiii ] Some of the senior positions held by Helgerson at the CIA are known; there appears to be an approximately five-year period between 1993 and 1998 when Helgerson’s positions are mostly unknown.

] The statement about the conflict of interest appears to indicate that Helgerson must have been involved in activities related to KSM in the mid-1990s, but this is not certain.
