HOUSTON (Reuters) - Energy giant BP Plc said on Tuesday it had sharply increased the amount of oil it was capturing from its blown-out Gulf of Mexico well, but U.S. officials want to know exactly how much oil is still gushing out.
The London-based company's share price fell 6 percent in London trading after U.S. President Barack Obama said he wanted to know "whose ass to kick" over the massive spill.
