BP accused of withholding 'critical' spill data

WASHINGTON: The company that owned the oil rig that exploded in the Gulf of Mexico is accusing BP of withholding critical evidence needed to investigate the cause of the worst offshore oil spill in U.S. history, according to a confidential document obtained by The Associated Press. BP called the claims a publicity stunt.

The new complaint by Transocean follows similar complaints by U.S. lawmakers about difficulties obtaining necessary information from BP in their investigations.
