The company previously owned and operated the now-demolished Trump Plaza and Trump World's Fair, the now-closed Trump Marina, Trump Casino & Hotel in Gary, Indiana, Trump 29 in Coachella, California, and Trump Taj Mahal in Atlantic City. It was founded in 1995 as Trump Hotels & Casino Resorts by Donald Trump, who after 2004 held only a minority ownership. The company filed for bankruptcy in 2004, 2009 and 2014.
