Donald Trump hired former top casino regulator Mike Rumbolz to head his Nevada operations, an indication that the financier intends to become an active player in that state’s gambling industry. Trump, who recently sold a large part of his New Jersey gambling empire to Merv Griffin, last month got federal antitrust clearance to buy more than 15% of the stock of Caesars World Inc., which owns one of the premier Las Vegas hotel-casinos, Caesars World. Rumbolz, whose term as chairman of the Nevada Gaming Control Board expired in December, said he had been negotiating with Trump since January.
