ADVANCE FOR TUESDAY, JAN. 27 AND THEREAFTER -M In this photo taken Nov. 6, 2010, Overseas Private Investment Corporation (OPIC) President and CEO Elizabeth Littlefield, is seen in Mumbai, India. A failed U.S. government-backed plan to produce environmentally friendly energy in one of Africa’s poorest countries was marred by insider connections and questionable planning, an Associated Press investigation found. The federal agency at the center of the deal is one of the government’s biggest secrets and routinely escapes public scrutiny. That agency, the Overseas Private Investment Corporation, approved three loans totaling $217 million to help a company, Buchanan Renewables, convert nonproducing rubber trees into biomass chips that would help power Liberia.
