That is where the US officials/Government always sound fishy in such matters because at present Hosni Mubarak is of no use to them thus the investigation. Of course Mubarak has been doing this siphoning for years and they knew (partner in crime in fact to the people of Egypt..); I am in fact very impressed with how Egypt is handling the issue for it is an old time story were we always here frauds of milllions in pounds and dollars but they just let go of the sit but not what they got while in the sit. The US have been said to have head been aware since Regan's time (late 70s..) HAYA mambo ya US na mambo of their interference always has to do with what they wll get at end of the day!! the part of the story below shows how they have always been tangled with Gaddafi as well as Mubarak though then declared as the bag of Anwar Sadat PLEASE observe the following;
White House Knowledge The mysterious fortune of ousted Egyptian president Hosni Mubarak got an early boost from millions of dollars in cash bribes delivered by CIA-connected arms merchants in the late 1970s
Former CIA officers Thomas Clines and Edwin P. Wilson claimed that President Ronald Reagans White House knew of the bribery and how much Mubarak and Sadat walked away with. Besides helping Sadat and Mubarak build their personal fortunes, the cash from the EATSCO deal strengthened their ties to the U.S. government, according to Wilson. However, the sweetheart EATSCO contract ran into trouble in the early 1980s when Pentagon investigators found that EATSCO had skimmed some $8 million from U.S. weapons sales. As a result of the investigation, EATSCO paid over $3 million in penalties. Clines was personally assessed $110,000 for filing false invoices. Hussein Salem, a close friend and associate of Mubaraks, pleaded guilty and paid a $40,000 fine.
In that same time frame, Wilson was arrested on charges of shipping explosives to Muammar Gadhafis regime in Libya. Though Wilson claimed he was sent to Libya by senior CIA official Ted Shackley to spy on Gadhafis terrorist operations, a CIA affidavit was submitted at Wilsons trial denying any substantive CIA contacts with Wilson after his intelligence career officially ended in 1976. At the 1983 trial, that affidavit persuaded the jury that the CIA had not authorized Wilsons assistance to Gadhafi. The ex-CIA officer was convicted and sentenced to 52 years in prison. However, in 2003, Wilson managed to pry loose an internal memo describing doubts among government lawyers regarding the truthfulness of the affidavit. The lawyers nevertheless had used it to secure Wilsons conviction.
The discovery of this prosecutorial abuse after Wilson had been imprisoned for two decades, including much of it in the high-security prison in Marion, Illinois led a furious U.S. District Judge Lynn N. Hughes to vacate Wilsons conviction for selling military items to Libya.
There were, in fact, over 80 contacts, including actions parallel to those in the charges, Hughes declared. The government discussed among dozens of its officials and lawyers whether to correct the testimony. No correction was made.
Editors Note: After publication of this story, former U.S. intelligence officer Edwin Wilson contacted us and disputed the quotes and other comments attributed to him. When asked about Wilson's complaint, author Morgan Strong said he stands by the accuracy of the quotes.
