Bush's grandfather, Prescott Bush, and Prescott's father-in-law, George Herbert Walker, helped finance the rise of the Nazi Party through their intimate entanglements with Nazi industrial, shipping and banking interests. This long (and well-documented) collaboration continued even after America was at war with Nazi Germany. … The Walker-Bush cabal's Nazi partners also helped finance – then profited from – the Auschwitz camp.Federal documents show that the Bush/Nazi dealings continued until at least 1951. Also here and here and here.
Finally, in 1942, the U.S. government seized the Walker-Bush Nazi assets under the Trading With the Enemy Act (the cash value was returned to Prescott in the 1950s, helping to fund his Senatorial race, and going into a trust fund that helped G.H.W. Bush in his political bids, including his runs for President, as well).
P.S.: Another DU poster notes that Cheney "and his daughter went back the next day to lay flowers at the wall. He was dressed appropriately then. … I'm sure the 2nd day photo will be the official one ..."
