Thank you. That's very helpful.
Just to clarify a point made earlier by Mr. Strahl, he made an analogy between the United States' position on buy American and its position on Keystone XL, stating that Keystone and buy American were campaign commitments. I was just on the Biden campaign website to be sure and there was no specific campaign commitment to buy American like there was for Keystone XL. I wonder if you see these two situations as quite different.
