It would be nice if you people would look stuff up for yourselves.
Buried in the Department of the Treasury’s 2003 Financial Report of the United States Government is a short section titled “Unreconciled Transactions Affecting the Change in Net Position,” which explains that these unreconciled transactions totaled $24.5 billion in 2003.[2]
The unreconciled transactions are funds for which auditors cannot account: The government knows that $25 billion was spent by someone, somewhere, on something, but auditors do not know who spent it, where it was spent, or on what it was spent. Blaming these unreconciled transactions on the failure of federal agencies to report their expenditures adequately, the Treasury report concludes that locating the money is “a priority.”
The unreconciled $25 billion could have funded the entire Department of Justice for an entire year.
And this shows that NASA has been stealing money how... It says the government can't account for the money, that doesn't mean NASA is pocketing it all.
Edit: Correct me if I'm wrong, but does the government not give NASA a set amount of money? If this is the case, than how could NASA be the one making money if their money is accounted for, and it's the GOVERNMENT who can't find their money?
