Brent Wilkes, the defense contractor implicated in the Duke Cunningham bribery scandal and possibly in the developing investigation of Rep. Jerry Lewis, talks to the New York Times about his lucrative career trading campaign cash for earmarks - or what he calls "transactional lobbying." Wilkes sheds light on the relationship between lobbyist Bill Lowery, a former congressman, and House Appropriations Committee Chair Jerry Lewis (R-CA).  Lowery taught Wilkes the ropes of flooding the system with money and winning earmarks in return.  Wilkes says:  “Lowery would always say, ‘It is a two-part deal [...] Jerry will make the request. Jerry will carry the vote. Jerry will have plenty of time for this. If you don’t want to make the contributions, chair the fund-raising event, you will get left behind.’ ”
