The pipeline he closed down construction on, Keystone XL, would replace train cars and carry Canadian Tar Sands to a refinery, where it is processed and sent to other countries. The 10,000 jobs you cite are disinformation. It was estimated that up to 10,000 temporary jobs would be created over the life of the pipeline. The company that owns the pipeline, says the number is now about 1,000. So, the products created by the tar sands would not be sold in this country and would not affect the price of our oil/gas. Try a few facts, next time. Spreading disinformation just makes you look like a sore loser.
