It's much worse than originally thought.

NASA has released photos of the oil spill in the Gulf and experts are fearing the worst.

The slick is spreading.

The State Department says the U.S. and Cuba have held talks about what's to be done in the Caribbean, and environmental groups are asking the federal government to take over all monitoring and testing related to the Gulf of Mexico oil spill.

CNN's Brian Todd has been following the story and says there's also concern about the oil reaching as far north as North Carolina. He brings us an update today.
