Crews mop up oil on Yellowstone River

LAUREL — The scope of Exxon Mobil Corp.'s oil leak into the Yellowstone River could extend far beyond a 10-mile stretch of the famed waterway, the company acknowledged under political pressure Monday.

As the company intensified its cleanup of tens of thousands of gallons of spilled crude, Exxon Mobil Pipeline Co. President Gary Pruessing pledged to do "whatever is necessary" to find and mop up oil from the 12-inch pipeline that broke at the bottom of the river over the weekend.
