"Trump owes hundreds of millions of dollars to a variety of lenders, giving his bankers a huge amount of potential leverage over the man who will soon occupy the most powerful office in the world. Already there are concerns about Trump's biggest lender, the troubled Deutsche Bank, which he owes at least $364 million. On Friday, Reuters reported that his second-biggest lender, a small Wall Street firm called Ladder Capital Strategies, may be putting itself up for sale to the highest bidder. Public records show Trump owes the firm at least $282 million, on four lines of credit. This means that other big money players—Wall Street firms, American banks, overseas banks, financial institutions partly owned by foreign governments—could move to buy up the debts of a US president and create a host of conflicts of interest."
