Statoil is one of the companies who started moving oil by rail to get around Obama.

There are those that think that “getting around Obama” was designed to put money in the pockets of Warren Buffet and Bershire Hathaway, since they apparently own a lot of the key railroads. I never looked into it closely, but it seemed plausible. Warren has a lot of rent-seeking behavior in his interactions with government.
