An Egyptian newspaper has published allegations that the Mubarak family skimmed monies from ticket sales of travelling exhibits of Egyptian antiquities. See
The report also indicates that Zahi Hawass (is he in or out?) has denied the allegations.
One suspects this is just the tip of the iceberg. The other question that should be investigated is whether US archaeologists or institutions that helped facilitate these exhibits also helped facilitate such corrupt practices.
US Government prosecutors have shown how aggressive they can be in breaking up alleged smuggling rings for Egyptian artifacts of limited cultural and artistic value. But, how aggressive are they when it comes to investigating corrupt practices that may have bilked US institutions and tax payers out of millions of dollars? Not very, apparently.
