What the investigators realized about the BAE money and the US was that almost 2 billion dollars in Britain was gone to the west from Bae system.
This large sum of money was transferred into the Saudi Ministry of Defence and Aviation bank accounts controlled by Prince Bandar. It was found out that the BAE have been spending large amounts of money for personal pleasures - the company has lost billions of dollars because its important employees were using the company's money within their personal lives.
