The brother of embattled State Department Inspector General Howard Krongard has quit as an adviser to Blackwater Worldwide.
Alvin Krongard's resignation Friday came two days after the relationship with the North Carolina-based security contractor was sharply criticized by a congressional oversight committee.
Erik Prince, Blackwater's top executive, says the conflict of interest questions raised by the connection prompted Alvin Krongard to submit his resignation.
Prince says Alvin Krongard never received any payment for his work on Blackwater's advisory board, which only met once.
Due to the relationship, Howard Krongard was forced to step aside from any inquiries related to the company, a major State Department contractor and the subject of ongoing federal investigations.
