Trump has been debanked since the late 90s by almost all US banks, because when you bankrupt two casinos and frequently spend time with mobsters they considered loans to you "high risk" for some reason.
He's been getting loans via Europe (mostly Deutschbank.. which is also Putin's bank of choice), and Russia, for 30 years.
That is, until he won the lottery by convincing the stupidest people alive to vote him into the highest seat of power.
So now it's payback time against all the banks he thinks wronged him.
