According to CNN the Justice Deparment wants the guilty verdict against former Republican Senator Ted Stevens of Alaska set aside. The article cites the request amid charges by an FBI agent of prosecutorial misconduct. Evidently there was an interview of the contractor that was withheld by the government from the defense. The contractor valued the services provided to Stevens much less than he testified to during the trial.
Stevens lost a re-election bid in November to Democrat Mark Begich, who had been Anchorage's mayor. I wonder whether the FBI agent was a Democrat.
