(CNN) -- As the first week of the John Edwards federal criminal trial comes to an end, where the former Democratic senator and presidential candidate is accused of using hundreds of thousands of dollars of donations to conceal his affair with a campaign videographer without reporting the money to federal authorities, we wanted to take a look back at some statistics about other politicians in trouble.
