Back in the United States, a new scandal is unfolding at the Justice Department today. Nine months before agreeing to delay an environmental cleanup by the energy giant ConocoPhillips, the government’s top environmental prosecutor purchased a million-dollar vacation home with the company’s vice president and its top lobbyist. The prosecutor, Assistant Attorney General Sue Ellen Wooldridge, resigned last month. Just before departing, she agreed to grant ConocoPhillips as much as three more years to install pollution controls at nine of its refineries.
