Senator, who conducted the five studies you cite? I would challenge their conclusion. The original Keystone pipeline had fourteen significant spills in the first twelve months of operation; not environmentally friendly. Additionally, if the tar sand isn't brought through the pipeline, it in all likelihood will not touch U.S. soil but will go to tankers straight to China, or India; but certainly not here. The tar sand oil is not destined for the U.S. market. Therefore, I would like you to explain the benefit of the Keystone XL to the U.S. consumer.
