"The federal government is heightening the pressure on BP, pushing the oil company to do more to stop well leaks gushing thousands of barrels of oil into the Gulf of Mexico and to beef up its response to the potential environmental impact on the coast. ""We'll continue to urge BP to leverage additional assets,"" U.S. Secretary of Homeland Security Janet Napolitano told reporters on Friday as the massive oil slick approached the Louisiana coast. ""It is time for BP to supplement their current mobilization as the slick of oil moves toward shore."" BP, which owns the ruptured well, said officials expect oil to reach land sometime Friday, with Venice and Port Fourchon the first places likely to be affected. Doug Suttles, chief operating officer of BP, said the company has had only three priorities since the April 20 rig explosion that led to the oil spill: stop the flow of oil, minimize its impact and keep the public informed."
