Obama to do everything 'humanly possible' on spill

No remedy in sight, President Barack Obama on Sunday warned of a "massive and potentially unprecedented environmental disaster" as a badly damaged oil well a mile (1.6 kilometers) deep in the Gulf of Mexico spewed a widening and deadly slick toward delicate wetlands and wildlife. He said it could take many days to stop.

Obama rushed to southern Louisiana to inspect forces arrayed against the oil gusher as Cabinet members said the situation was grave and insisted the administration was doing everything it could. (AP)
