Fortune: Big Oil's big man in Washingtonupdated: Tue Jun 21 2011 09:19:00

Shortly after he arrived at the powerful oil-industry lobbying group, President Obama and a wave of Democrats swept into office, promising to fund alternative energy sources and take action on climate change. Last year the BP disaster poured more than 200 million gallons of oil into the Gulf of Mexico, and Gerard spent the summer prepping his members for more than 50 congressional hearings and eight separate investigations related to the spill and its aftermath. Then, in mid-May, executives from five oil companies appeared before a committee of the U.S. Senate and defended their earnings, which could hit record highs in 2011. "Don't punish our industry for doing its job well," Chevron CEO John Watson said. The performance was, by all accounts, a public relations disaster.
