The National Oceanic and Atmospheric Administration greatly expanded the fishing ban in the Gulf of Mexico on Tuesday in response to spreading oil from the BP well blowout. The prohibited area now covers 19 percent of the gulf, nearly double what it was, according to the agency.
In Washington, Interior Secretary Ken Salazar appeared before Congress for the first time since the well exploded a month ago. Mr. Salazar acknowledged that the Minerals Management Service, the Interior Department agency responsible for policing offshore drilling, had been weakened by corruption and lax enforcement of safety and environmental rules.
