This week's guest on Open Mic is Ed Hamberger, President and CEO of the American Association of Railroads. In this week's interview Hamberger discusses the longstanding relationships between agriculture, railroads and feeding the world. But the industry is facing economic and regulatory challenges that could negatively affect the rail industry and its customers. The AAR supports expanded global trade through the Trans-Pacific Partnership and is hopeful a new Congress can bring needed change to corporate tax laws.Jeff NalleyEd Hamberger, Pres.
