Not likely because the really, really big fish in that pond was a democrat
Assuming this Harriman did work with the Nazis as Prescott Bush did, did he and his family go on to lead the Democratic party?
Now I know Prescott Bush wasn't prosecuted for collaborating with the enemy here in the states, but he was stripped of his companies and wealth in England under the Trading with the Enemy Act. Perhaps Harriman was as well?
I only know that you're defending a Nazi collaborator indeed an important Nazi financier, by saying someone else did it too. Bravo. Next you'll explain how the people who attacked us on 9/11 own lots of politicians, not just the Bush family.
