Republican lobbyist Jack Abramoff was sentenced Thursday to four years in jail for corruption and tax offenses. Abramoff is already serving a nearly six-year term on unrelated charges. The new sentence will be served at the same time, meaning he will not spend any extra time behind bars once his original sentence ends in 2012. We speak with journalist Peter Stone, author of Heist: Superlobbyist Jack Abramoff, His Republican Allies, and the Buying of Washington. [includes rush transcript]
