WASHINGTON, D.C. ? A former U.S. Army Reserve officer has agreed to plead guilty to playing a key role in a kickback scheme that steered millions of dollars in Iraq reconstruction contracts to one businessman.

Bruce D. Hopfengardner served as a special adviser to the U.S.-led occupation forces, recommending funding for projects on law enforcement facilities in Iraq.

Documents filed Friday in U.S. District Court said Hopfengardner will plead guilty to conspiring with Philip H. Bloom, a U.S. citizen with businesses in Romania; Robert J. Stein, a former Defense Department contract official, and others to create a corrupt bidding process that included the theft of $2 million in reconstruction money.

Bloom and Stein already have pleaded guilty to charges stemming from the scheme that paid more than $2 million in bribes to officials. No hearing has been set for Hopfengardner’s guilty plea in U.S. District Court.
