The sums that Trump owes are unprecedented for a US president. Richard Painter, a University of Minnesota law professor who served as George W. Bush’s chief ethics officer, says Trump’s situation is unique. There have been presidents who possessed enormous wealth, including John F. Kennedy and Franklin D. Roosevelt, and the main concern at the time about them was whether they would use the presidency to enrich themselves further. That might be true for Trump, too. But Painter points out that in the case of the Deutsche Bank loans, Trump is not the party with the leverage because he owes the bank.
