Lawrence Summers was the president of Harvard University and a former Secretary of the Treasury of the United States.
Gerry Rankin claimed to have met with Summers regarding his supposed work as a United Nations economist. A check of Summers' office by Detectives Robert Goren and Alexandra Eames proved that no such meeting took place, as Summers had been in Africa at the time. This showed that Rankin's claim was part of his bogus lifestyle. (CI: Phantom)
