ALEXANDRIA, Va. – The infamous $90,000 in cash found in the freezer of a former Louisiana congressman accused of taking bribes is evidence of nothing more than a failed FBI sting, a defense lawyer told jurors Tuesday. William Jefferson, a Democrat who represented parts of New Orleans until losing his re-election bid last year, is charged with soliciting bribes, racketeering, money laundering and other crimes. Prosecutors say he received more than $500,000 and sought millions more in exchange for using his influence to broker business deals in Africa.
