If you paid attention to what was being revealed you might realize that the evolving story indicates that his "billion dollar industry" might be built in significant part on favors that relate to Deutsche Bank loans, Russia mafia real estate complexes in Florida, and a huge number of new businesses ventures in places like Moscow and shoulder-rubbing with oligarch investors tied closely to Putin and the Kremlin (he has also done this in Saudi Arabia, btw).
In other words, a rational suspicion is that he helped rebuild his "billion dollar industry" following one of his six major bankruptcy filings using dirty Russian money and unsavory favors that may go all the way back to the Kremlin itself. Considering that much of the man's "industry" consists of stranding time share purchases and other independent builders who have participated in his branded projects, not to mention his large settlement with the government to make his Trump U fraud case go away, where he swindled hundreds (possibly thousands) of people who believed in him most, a deal that wouldn't be available to anyone not sitting in the President's chair, and probably would have sunk him if Hillary had won, it's quite credible.
A substantial portion of his "industry" is the con artist business.
