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 ??
The Anti-Defamation LeaguePrescott Bush's Alleged Nazi "Ties" "Rumors about the alleged Nazi "ties" of the late Prescott Bush, the grandfather of President George W. Bush, have circulated widely through the Internet in recent years.
These charges are untenable and politically motivated.
Despite some early financial dealings between Prescott Bush and a Nazi industrialist named Fritz Thyssen (who was arrested by the Nazi regime in 1938 and imprisoned during the war),
Prescott Bush was neither a Nazi nor a Nazi sympathizer."
