BP sprays more chemicals into main Gulf oil leak

ON THE GULF OF MEXICO (AP) — A remote-controlled submarine shot a chemical dispersant into the maw of a massive undersea oil leak today, further evidence that authorities expect the gusher to keep erupting into the Gulf of Mexico for weeks or more. Crews using the deep-sea robot attempted to thin the oil — which is rushing up from the seabed at a pace of about 210,000 gallons per day - after getting approval from the Environmental Protection Agency, BP spokesman Mark Proegler told The Associated Press.
