Richard J. Griffin
As the Assistant Secretary of State for Diplomatic Security appointed by George W. Bush, he made key decisions regarding the department's oversight of private security contractor Blackwater USA. After a critical review by the House Oversight Committee found that his office had failed to adequately supervise them during the Blackwater Baghdad shootings protecting U.S. diplomats in Iraq, he resigned in November 2007.
