Donald Trump is getting hit with a lawsuit for a whopping $4 billion in Las Vegas. The plaintiff, Nights at Vegas, Inc., is a licensed management company that handles the leasing of many properties in the Donald's new Trump International Hotel & Tower. According to legal papers obtained by TMZ.com, their complaint is that the real-estate mogul, who runs a competing leasing organization for units in the building, won't let them use his own name in order to market the rentals. In other words, they can't use the Trump brand to drum up interest. Trump's own leasing agency charges owners more (50 percent of rental income, as opposed to the 20 percent that Nights at Vegas charges), which put it at a disadvantage without the no-branding rule. Still, both the suit and Trump's marketing mandate come as a surprise. This may officially be the first time in history the Donald has ever asked people to stop saying his name.
