You'll hear the name of the eventual forty-fifth President of the United States throughout WrestleManias IV and V, and "The Donald" popped up in the front row of both. Gorilla Monsoon and Jesse Ventura made copious references to the events taking place at Trump Plaza, but that's a wee bit untrue.
Trump Plaza was the name of a hotel/casino on the Atlantic City Boardwalk that opened in 1984, while the event itself took place at Boardwalk Hall, site of future episodes of Raw and SmackDown, as well as an annual house show these days, usually in the weeks before WrestleMania.
So why was the show billed as being from "Trump Plaza"? Because Vince McMahon's old friend Trump sponsored both 'Manias IV and V, getting the "naming rights" in trade.
