The Louisiana Democrat began serving a 13-year prison sentence in May after he was convicted three years ago for orchestrating a plot to bribe African officials that culminated with government investigators finding $90,000 hidden in his freezer.

The appeals court rejected Jefferson's argument that the federal bribery statute prosecutors used to convict him wasn't applicable because the scheme wasn't related to his official duties.
