"A number of the proposals that the United States has put on the table have little or no support from the U.S. business and agriculture community. It isn't clear who they're intended to benefit", said John Murphy, vice-president of the U.S. Chamber of Commerce. Pat Roberts, the senior US senator from Kansas, called for an outcry against Trump anti-NAFTA moves, saying the "issues affect real jobs, real lives and real people". Kansas is a major agricultural exporter, and farm groups warn that just threatening to leave NAFTA might cause buyers to minimize uncertainty by seeking out non-US sources.
