U.S. charges Obama fund-raiser in $290 million fraud

The announcement follows last month's indictment of Nemazee, head of a private equity firm and an Iranian American Political Action Committee board member, on one count of defrauding Citigroup's Citibank.

The new indictment adds allegations that he defrauded two other banks, Bank of America and HSBC Bank USA, in a similar fashion by falsifying documents and signatures to purportedly show he had hundreds of millions worth of collateral.
