Iraq: weapons focus of criminal inquiry; largest fraud ring yet?

Snip from NYT article by James Glanz and Eric Schmitt:

Several federal agencies are investigating a widening network of criminal cases involving the purchase and delivery of billions of dollars of weapons, supplies and other matériel to Iraqi and American forces, according to American officials. The officials said it amounted to the largest ring of fraud and kickbacks uncovered in the conflict here.

The inquiry has already led to several indictments of Americans, with more expected, the officials said. One of the investigations involves a senior American officer who worked closely with Gen. David H. Petraeus in setting up the logistics operation to supply the Iraqi forces when General Petraeus was in charge of training and equipping those forces in 2004 and 2005, American officials said Monday.
