McConnell's got to know someone in the 'hemp' business and stands to profit is the only thing I can figure. He has already successfully attached language to broader legislation in the 2014 Farm Bill and annual spending packages, that protects state industrial hemp research programs from federal interference.
More than 30 states have 'industrial hemp' projects. Florida is thinking of jumping on the bandwagon. Right now they are researching the risk of any hemp plants becoming invasive threats to Florida’s environment. I saw some humor in that one; as I couldn't help but wonder how from an aerial view you'd be able to tell the difference between marijuana and hemp?
