10 Jack Abramoff
Prison sentence: 6 years
Before he was convicted for financial crimes, he was a lobbyist. To some, being a lobbyist is a crime itself. He confessed to his crimes in 2006, pleading guilty to fraud, conspiracy, and tax evasion. He also admitted to cheating a casino for around $85 million. Additionally, he was guilty of bribing Republican Ohio Representative Bob Ney.
