Waste was not limited to mismanagement, however. Sometimes it was criminal, the report found.
"In late 2005, several U.S. citizens were criminally charged with respect to the handling of these funds—and have since pled guilty. In February 2007, five more were indicted, of whom four were convicted and one pled guilty," CRS reported.
Doesn't End with the End of War
The U.S. began disengagement with Iraq two years before the official withdrawal in 2011. However, money has not stopped flowing to the country.
Watch: Is Iraq seeing an Iran-Saudi Arabia proxy war?
According to foreignassistance.gov, $3.1 billion in foreign assistance has gone to Iraq since 2009. The peak year was 2011, when the U.S. sent $1.2 billion; the lowest year was 2014, when $48 million was sent.
SIGIR closed shop in 2013, but not before conducting one final audit of Iraq reconstruction spending. The audit found that $220.2 billion had been provided to Iraq for reconstruction and development projects and the Iraqi military – with the United States providing $61 billion (the rest came from international assistance and $146 billion through the Iraqi capital budget).
The final review of how this money was spent is damning. The findings show that the United States was unable to adequately track where and how money was spent because of gaps in reporting. This led to numerous instances of missing money.
