The second transaction that Green made with the credit card, in June of 2007, is described as "Romney for President" for $100. The Romney campaign was also the beneficiary of a later donation, as well campaigns conducted by Gov. Rick Perry and U.S. Rep. Michele Bachmann.
The system failed at two levels. First, internal controls failed to ensure Water District funds were spent appropriately. Who reviewed and signed off on Green's monthly credit card statements?
Second, who conducted the Water District's annual fiscal audit? Sarbanes-Oxley was intended to identify fraudulent use of funds by higher ups.
Five years with no internal controls and no effective audit? It sounds like the National Republican Congressional Committee (NRCC).
Update 1-29-13: Green will serve one year in federal prison, face two years parole and pay a $3,000 fine for his crimes.
