I heard an hour long documentary on him on Sirius radio.
Home Depot wanted to open a new store in New Orleans. They were having lots of zoning problems etc.
Nagin cleared up all the problems and allowed Home Depot to build the new store.
In exchange, Home Depot had to sign a contract with a granite countertop company owned by Nagin, and managed by his two sons.
They had it set up where Home Depot would buy over a quarter million dollars a year in countertops from this company.

After about 7 months, Home Depot cancelled the contract, despite being in political debt to Nagin.
The countertops were not installed on time and the quality was crap.

Nagin was a crooked as they come. He is doing 10 years in federal prison and still denies any wrongdoing in all the bribes concerning the Katrina rebuilding. He says that all his problems are due to "racism."
What a piece of work.
