Here is the most complete article on the "scandal" to which you refer.

Good luck convincing folks that what he did was corrupt. Pork maybe, but if that is the case, all members of congress would be in jail. $7000 in campaign contributions over several years is peanuts.
I don't know why you pulled the $7000 number out to post, when the article clearly ALSO states:
"Between 1992 and 1997, Audre employees and family members donated $77,000 to members of Congress.Rep. Duncan Hunter"
It is clear to me that Hunter is the typical politico; accepting contributions of large proportions, through various screened contributors to funnel them, and rewarding specific donrs with millions in contracts.
I don't know where Fred Thompson has done the same....
