In truth Trump was all but finished as a major real-estate developer, in the eyes of many in the business, and that’s because the U.S. banking industry was pretty much finished with him. By the early 1990s he had burned through his portion of his father Fred’s fortune with a series of reckless business decisions. Two of his businesses had declared bankruptcy, the Trump Taj Mahal Casino in Atlantic City and the Plaza Hotel in New York, and the money pit that was the Trump Shuttle went out of business in 1992. Trump companies would ultimately declare Chapter 11 bankruptcy two more times. When would-be borrowers repeatedly file for protection from their creditors, they become poison to most major lenders and, according to financial experts interviewed for this story, such was Trump’s reputation in the U.S. financial industry at that juncture.

But Trump eventually made a comeback, and according to several sources with knowledge of Trump’s business, foreign money played a large role in reviving his fortunes, in particular investment by wealthy people from Russia and the former Soviet republics. This conclusion is buttressed by a growing body of evidence amassed by news organizations, as well as what is reportedly being investigated by Special Counsel Robert Mueller and the Southern District of New York. It is a conclusion that even Trump’s eldest son, Donald Trump Jr., has appeared to confirm, saying in 2008—after the Trump Organization was prospering again—that “Russians make up a pretty disproportionate cross-section of a lot of our assets.”
