Once again, for the really, really slow (stupid) people in the class, if you can't remember this please write it down.The Dept of the Treasury!!
The Treasury isn't a source of money. It is a repository for money collected from a source of money.
To say "debt of the treasury" you are referencing either money that has already been spent and doesn't exist anymore, or additional debt to be incurred by accepting money from some source of money.
To answer the question, you actually have to identify a source of money.
Where will the money come from to pay for Obama's government?
