United States Agency for International Development
The United States Agency for International Development (or USAID) is the United States federal government  organization responsible for most non-military foreign aid. An independent federal agency, it receives overall foreign policy guidance from the United States Secretary of State and seeks to "extend a helping hand to those people overseas struggling to make a better life, recover from a disaster or striving to live in a free and democratic country..." 
USAID advances U.S. foreign policy objectives by supporting economic growth, agriculture and trade; health; democracy, conflict prevention, and humanitarian assistance. It provides assistance in Sub-Saharan Africa; Asia and the Near East, Latin America and the Caribbean, Europe, and Eurasia. USAID is also organized around four main pillars: Global Development Alliance; Economic Growth, Agriculture, and Trade; Global Health; Democracy, Conflict, and Humanitarian Assistance.

# Origins of USAID
USAID's origins date back to the Marshall Plan reconstruction of Europe after World War II and the Foreign Assistance Act into law and by executive order established USAID by consolidating U.S. non-military foreign aid programs into a single agency.  As a part of the U.S foreign affairs restructuring laws enacted in 1999, USAID was established as a statutory independent agency under section 104 of title 5 of the United States Code. (5 USC 5312 et seq)

# USAID in the context of U.S. foreign aid
At the Earth Summit in Rio de Janeiro in 1992, the most of the world's governments adopted a program for action under the auspices of the United NationsAgenda 21, which included an Official Development Assistance (ODA) aid target of 0.7% of gross national product (GNP) for rich nations, roughly 22 members of the OECD, known as the Development Assistance Committee (DAC).  The United States never agreed to this target but remains -- in real terms -- the world's largest provider of official development assistance. However, relative to its economy, the U.S. is the 21st largest provider with a 0.17% of GNI in aid.
According to the Development Assistance Committee of the Organization for Economic Cooperation and Development (DAC/OECD), the United States remains the largest donor of "official development assistance" at $23.53 billion in 2006.  DAC/OECD reports that the next largest donor was the United Kingdom ($12.46b).  The UK was followed (in rank order) by Japan ($11.19b), France ($10.60b), Germany ($10.43b), Netherlands ($5.45b), Sweden ($3.95b), Spain ($3.81b), Canada ($3.68b), Italy ($3.64b), Norway ($2.95b), Denmark ($2.24b), Australia ($2.12b), Belgium ($1.98b), Switzerland ($1.65b), Austria ($1.50b), Ireland ($1.02b), Finland ($0.83b), Greece ($0.42b), Portugal ($0.40b), Luxembourg ($0.29b) and New Zealand ($0.26b). 
USAID states that "U.S. foreign assistance has always had the twofold purpose of furthering America's foreign policy interests in expanding democracy and free markets while improving the lives of the citizens of the developing world."  However, some critics say that the US government gives aid to reward political and military partners than to advance genuine social or humanitarian causes abroad.

In June 2003, C-SPAN followed USAID Admin. Andrew Natsios as he toured Iraq. The special program C-SPAN produced aired over four nights.  
USAID itself is transparent on the information distributed to the public about its operations in Iraq.  Detailed weekly reports, contracts and special reports are a part of the agency's web site on Iraq.
