Didn't Bush's grandpa support the Nazis?
Yes.
Prosecuted under US law (trading with the enemy act).
Look up (Google) Prescott Bush - I.G.Farben (German pharmaceutical giant)
After the seizures in late 1942 of five US enterprises he managed on behalf of Nazi industrialist 'Fritz Thyssen', Prescott Bush, the grandfather of President 'George W. Bush', failed to divest himself of more than a dozen enemy national relationships that continued until as late as 1951, newly-discovered US government (FOI) documents reveal.
Furthermore, the records show that Bush & his colleagues routinely attempted to conceal their activities from government investigators.
Bush's partners in the secret web of Thyssen-controlled ventures included former New York Governor W. Averell Harriman & his younger brother, E. Roland Harriman. Their quarter-century of Nazi financial transactions, from 1924-1951, were conducted by the New York private banking firm, Brown Brothers Harriman.
Very telling, is it not ??
