WASHINGTON, Aug 5 (Reuters) – Former U.S. Representative William Jefferson, who was caught with $90,000 in cash in his freezer, was found guilty on 11 of 16 charges related to a bribery and money laundering scandal, a U.S. official said on Wednesday. The ex-Louisiana lawmaker was accused in 2007 of soliciting millions of dollars in bribes from a dozen companies while using his office to broker business deals in Africa. In a search of his residence, FBI agents said they had found the $90,000 in a freezer. Jefferson faces up to 150 years in prison and could face forfeiture of payments totaling $456,000, plus stock certificates, according a spokesman for the U.S. Attorney’s Office in Virginia, where Jefferson was tried. Jefferson can appeal his conviction.
