I recently started listening to the podcast Behind the Bastards, and in the first episode I listened to (The Business Plot), the hosts claim that Prescott Bush provided funding for a cabal of Wall Street investors who wanted to create a fascist shadow state in America. It even goes on to say that due to Bush's financial involvements in Nazi Germany, Bush was positioned by this group as the liason between their potential shadow state and the state of Nazi Germany.

While I can find a good deal of evidence for the "Business Plot" as a whole, and other aspects of how this podcast told and represented the story, this seems a sticking point. It seems they got the idea from an attorney named Scott Horton, who wrote out a lot of what BtB later reported as fact in his 2007 article 1934: The Plot Against America. A contributor on Wikipedia claims, without source itself, that "no evidence from the source material of the congressional report, or from news reports at the time, make any mention of Bush's involvement."

Is this true? I'm finding difficulty verifying this one way or the other. Is there a location where such news reports, Smedley Butler's writings, and the congressional report are archived?

Another link is Prescott Bush's financial interests. This 2004 article pointed out documents showing that Prescott Bush was a director and shareholder of a number of companies involved with Thyssen, the German steel magnate. Herbert Parmet is a historian who acknowledges the several financial ties between Prescott Bush and Nazi Germany, but concludes that Bush was not a Nazi sympathizer in ideology, but merely a capitalist who wasn't very discriminating in how he would make it (though that, of course, is worthy of its own criticism).

Is there any links that show this connection with Nazi interests went beyond a financial nature?
