From the Summary: "Many reconstruction efforts on the ground are underway, but security concerns have slowed progress considerably. Most reconstruction funding is targeted at infrastructure projects -- roads, sanitation, electric power, oil production, etc. Aid is also used to train and equip Iraqi security forces. A range of programs are in place to offer expert advice to the Iraqi government, establish business centers, rehabilitate schools and health clinics, provide school books and vaccinations, etc. However, of the $18.4 billion appropriated by Congress in October 2003, only $11.5 billion had been obligated and $3.5 billion spent by mid-February 2005. Congress approved on September 29 an Administration-proposed re-allocation of $3.5 billion in previously appropriated reconstruction funds to give greater emphasis to security, employment generation, and debt relief."
