This week's guest on Open Mic is US Senator Heidi Heitkamp. As an outspoken advocate for agriculture and rural America, the North Dakota Democrat was instrumental in crafting the 2014 farm bill and now has proposed legislation to address uncertainty over renewable fuels and waters of the US as well as expanding trade with Cuba. In this interview Senator Heitkamp shares her thoughts on food labeling and outlines senate debate over Trade Promotion Authority for President Obama. While trade dominates the legislative agenda this week, Heitkamp hopes for timely action on the highway trust fund, the export-import bank and national security issues.Jeff NalleySenator Heidi Heitkamp
