After three years, the bipartisan Commission on Wartime Contracting completed its business this week. In its final report to Congress (PDF), it estimates that the federal government has lost between $31 and $60 billion to contractor fraud and waste since the wars in Afghanistan and Iraq started. „The government was not prepared to go into Afghanistan in 2001 or Iraq in 2003 using large numbers of contractors, and is still unable to provide effective management and oversight of contract spending,“ said commission co-chairman Michael Thibault.
