10. Trump University
Trump University was open from 2005-2011 and offered business classes in a for-profit non-accredited model. The idea behind the school was to offer Trump’s business expertise in a series of classes that cost over $35,000. However, many students sued Trump when they claimed the classes were nothing more than extended infomercials. It officially shut down in 2011 and has been a topic of much debate in the 2016 presidential election.
