Republican gubernatorial candidate Bruce Rauner speaks to business students Aug. 29 in Barsema Hall. Rauner gave advice on investing in start-up businesses and discussed how he will use his experience in venture capitalism to promote job growth in Illinois if elected in November. “My favorite people in the world are entrepreneurs,” Rauner said. “They take risks, take a lot of grief. They have to be lucky, but they also have to be smart and good and tough, and it’s all about team building.”
