Crews work to stop oil leak from last week's rig explosion | al.com: "NEW ORLEANS -- Crews were using a robot submarine Sunday to try to stop an oil leak nearly a mile below the surface of the Gulf of Mexico, but officials said it would take at least another day before they knew whether the job was completed.
The Coast Guard said the oil spill was expected to stay 30 miles off the coast for the next three days, but officials are still keeping a watchful eye because the slick has the potential to threaten shores from Louisiana to Florida."
