Ken Silverstein at Harpers.org provides a look back at a career that looks to be coming to a premature close, that of Rep. William Jefferson’s (D-LA) job as a water carrier for Chevron. Here is one example of the "Congressman from Chevron’s" many actions:

In the mid-1990s, Chevron and several other oil companies led a successful campaign to block tough sanctions on the regime of Nigerian general Sani Abacha, who had a habit of stringing up his political enemies, and who also plundered the Nigerian treasury to the tune of about $1 billion a year during his five-year rule. The oil companies helped to produce a lobbying brochure that lauded the special quality of Nigerian crude and said that "any disruption to this supply of imported petroleum will severely impact the American economy.” Jefferson was one of only two members of the Congressional Black Caucus who opposed sanctions on the Abacha dictatorship.

According to Opensecrets.org Jefferson’s third largest contributor for his career is the lobby shop representing ChevronTexaco Jones, Walker. They have given Jefferson $47,379 since 1993.
