The Clinton Legacy. Remember Marc Rich? Clinton granted him a presidential pardon just before his term ended. It was widely believed that Rich's ex-wife bought the pardon through contributions to the Clinton Presidential Library.

The ink on Rich's pardon was still wet when he got into the middle of the oil-for-food scandal.

Former American fugitive Marc Rich was a middleman for several of Iraq's suspect oil deals in February 2001, just one month after his pardon from President Clinton, according to oil industry shipping records obtained by ABC News.

"Without that kind of middleman, the system would not work because the major oil companies did not want to deal with Iraq because there was a mandated kickback," said human rights investigator John Fawcett.
