He was very critical of Federal Reserve policy but was not as up-front as Murrary Rothbard on the "parasitic" evils of fractional reserve banking.  However, he was clearly supportive of the "controversial" information contained in the "Money Masters" videos, which was extremely critical of unhinged frb.  His support of the Monetary Reform Act is mentioned here.  No doubt others can find more "reputable" sources for his criticism of the Federal Reserve (which he clearly accused of causing the Great Depression).
