U.S. President Barack Obama said Wednesday the United States will take swift, coordinated and aggressive measures to respond to the earthquake disaster in Haiti, and he has directed the administration to focus on saving lives. Obama said the U.S. military has already mobilized its aerial relief team, overflying Haiti to assessed the damage. He said civilian search and rescue teams will begin to arrive within a few hours. He has tasked Rajiv Shah, director of the United States Agency for International Development (USAID) to be the administration's unified disaster coordinator. 'The people of Haiti will have the full support of the United States in the urgent effort to rescue those trapped beneath the rubble and to deliver the humanitarian relief -- the food, water and medicine -- that Haitians will need in the coming days,' he said.
