PDFs are [link|http://www.gao.gov/new.items/d02124.pdf|here] and [link|http://www.gao.gov/new.items/d02125.pdf|here]. I've only skimmed them them myself. The second seems to be what Huffington's addressing.
If anyone's intested in this topic, it might be better to read the original report than to take Huffington's article as gospel. The second report doesn't sound (to me) nearly as damning as Huffington claims.
Cheers,
Scott.
