This week’s guest on Open Mic is U.S. Senator John Thune. In this interview, the South Dakota Republican shares his frustration with the chamber’s failure to craft a national voluntary labeling bill for foods that contain ingredients from genetically enhanced crops. Senator Thune points attention to the role the minority must play in bringing the issue to a successful conclusion. Thune also addresses President Obama’s plan to cut crop insurance funding and questions the administration’s commitment to seeing congressional approval of the Trans-Pacific Partnership trade deal. While Senator Thune supports additional trade with Cuba, he has reservations about the steps President Obama has taken to normalize trading between the two countries.Jeff NalleySenator John Thune- SD
