More oil flows into Gulf of Mexico after accident

While BP struggled to restart its oil collection operation, the U.S. government said it would impose a more flexible ban on new deepwater drilling after a federal judge overturned an initial moratorium as too far-reaching.

Oil companies, trying to stop the government from keeping the ban in place, swiftly returned to court to ask the judge to enforce his ruling, accusing the Obama administration of choosing to "ignore and disobey it."
