Just running the family business:

Rumours of a link between the US first family and the Nazi war machine have circulated for decades. Now the Guardian can reveal how repercussions of events that culminated in action under the Trading with the Enemy Act are still being felt by today's president

George Bush's grandfather, the late US senator Prescott Bush, was a director and shareholder of companies that profited from their involvement with the financial backers of Nazi Germany.
The Guardian has obtained confirmation from newly discovered files in the US National Archives that a firm of which Prescott Bush was a director was involved with the financial architects of Nazism.
