The struggle to organize the steel industry, and after 1938, business attempts to erode Walsh-Healy and the Fair Labor Standards Act provided the backdrop for the feud. But activities of Nazi agents, working through William Rhodes Davis, increased Lewis' suspicions of Roosevelt's interventionist foreign policy and were important in the decision to support Wendell Willkie.
