Republican politicians in the United States are fighting President Barack Obama's decision to reject a controversial pipeline project.
They are trying to strip the president of his authority to decide the fate of the Keystone oil pipeline, which would carry oil from Canada through the United States to the Gulf of Mexico.
Republicans say Obama made the decision based on political considerations, and that the project would create thousands of jobs. Democrats, however, argue that a full environmental assessment must be carried out before the deal can be approved.
