Given Trumpolini's legal history I will never understand why folks & companies are so willing to throw money at his businesses...
https://en.wikipedia.org/wiki/Personal_and_business_legal_affairs_of_Donald_TrumpFrom 1973 until he was elected president in 2016, Donald Trump and his businesses were involved in over 4,000 legal cases in United States federal and state courts, including battles with casino patrons, million-dollar real estate lawsuits, personal defamation lawsuits, and over 100 business tax disputes
Fact is that he manages to bankrupt most of his business ventures.

His companies have filed for Chapter 11 bankruptcy six times. But he was always smart to put the burden of his business failures on investors while he made more money through salary, bonuses, and other benefits. He has never filled for personal bankruptcy which shows that he was making money from those bankrupt businesses.
Investors who put money into Trump's business are taking high risks. Maybe some of these Investors believe that he could use his position as president to bring more fortune to the company through market manipulation.
