New attempt to stop leak upcoming

BP will try this week to dump heavy mud on the well leaking in the Gulf of Mexico, but whether that will work remains to be seen. Some 6 million gallons of crude has flowed into the Gulf, though some scientists think the amount is higher. Interior Secretary Ken Salazar said he's not completely confident BP knows what it's doing. The spill's impact now stretches across 150 miles, from Dauphin Island, Ala. to Grand Isle, La., with 65 miles of Louisiana oiled. BP said Sunday that the amount of oil siphoned by the mile-long tube inserted into the well had sharply dropped over a 24-hour period. (Source: AP, 05/23/10)
