A New York man who laundered bribes for former Rep. Randy "Duke" Cunningham (R-Calif.) was sentenced to more than eight years in a federal prison, the Associated Press reports.

Thomas Kontogiannis had pleaded guilty to one count of money laundering. Prosecutors said that he had helped Cunningham launder hundreds of thousands of dollars in bribes to Cunningham from defense contractors.

Cunningham, who pleaded guilty in 2005 to accepting about $2.4 million in bribes, is serving more than eight years in prison.

Two contractors also linked to Cunningham have been convicted on charges that they gave kickbacks to Cunningham for help in obtaining government contracts.
