While this topic is somewhat controversial, the US depends on the use of corn and soybeans for a major part of its biofuel production. There is major ongoing research to use other biomass sources for biofuel production, but until these are more economically viable, corn and soy will continue to provide a valuable source of the nation's fuel supply.
It should be noted that, with modern production practices, there will be no shortage of either crop in the near future, barring a natural disaster. Were there no use of these crops for fuel, the nation would have a huge surplus of both crops.
