According to a February 10, 2011 "Reuters" article, Koch Industries—then owned by Charles G. Koch and David H. Koch, commonly referred to as the Koch brothers—were in a position to increase their profits substantially if the Keystone XL Pipeline were approved. By 2011, Koch Industries refined 25% of all crude oil imported into the United States. In response to the article, Congressmen Henry Waxman and Bobby Rush submitted a letter to the Energy and Commerce Committee urging them to request documents from Koch Industries relating to the pipeline.
