The lawsuit is one of three that accuse Trump University of fleecing students with unfulfilled promises to teach secrets of success in real estate at seminars that cost up to $35,000. The San Diego federal class-action lawsuit says Trump University, which no longer operates and wasn't accredited as a school, gave seminars and classes across the country that were like infomercials, constantly pressuring students to buy more, and in the end, failing to deliver. [...] the lawsuit says students were asked to rate the product when they believed they still had more instruction to come and were reluctant to openly criticize their teachers on surveys that were not anonymous.
