WASHINGTON, Nov. 23 (UPI) -- U.S. business mogul Donald Trump has threatened to spend millions of dollars on a presidential run if the Republicans fail to nominate a strong candidate.
In his new book, "Time to Get Tough," Trump also details his net worth -- he pegs it at $7 billion -- and says he is ready to sink a sizable chunk of his $270 million in liquid assets into a presidential bid, The Wall Street Journal reported Wednesday.
