Oil spill becoming an environmental concern.
Crews have been trying to stop an environmental nightmare in the Gulf of Mexico with crude oil pouring into the ocean, NBC reporter Leanne Gregg has the latest.
Robot submarines have been unable to shut off a well spewing thousands of gallons of oil into the Gulf of Mexico and so the idea of lighting the oil on fire has been mentioned. Officials are not sure it will work, but officials say they have to try it. It's part of a massive effort since last week's explosion of a drilling platform off the Louisiana coast that killed 11 people.
