the background facts are
that no bank other than DB would refinance the Trump organization (probably not because they were all in cahoots with Crooked Hillary?)
Ergo, it would be fair to suspect that something more than the standard collateral was involved.
DB had earned a reputation as the second go to choice for Russian money laundering., perhaps behind Wilbur Ross' Bank of Cyprus.
These are all previously established facts, but you know, TDS.
BTW, I assume that stiffing Russian oligarchs results in approximately the same as if you don't come up with the vig for Guido the Shark?
