Meanwhile, a number of mayors from across the country visited Louisiana on Monday, including Houston Mayor Annise Parker, to get a first-hand look at the spill.
Over the weekend, it was revealed that a BP document given to congress in early May says 100,000 barrels a day could leak if the blowout preventer is removed, as it has been. It's just the latest estimate in an ever growing list.
"BP has either been lying or grossly incompetent from day one," said US. Rep. Ed Markey of Massachusetts. "I think that they have been trying to limit their liability."
In addition, BP CEO Tony Hayward drew even more criticism when he was photographed this weekend yachting off the English coast.
As for Houston Mayor Annise Parker, she and other mayors visited New Orleans and other coastal communities in Louisiana to get a better understanding of efforts to contain the spill. They also met with local fishermen and took a boat tour of the oil soaked marshes, before sitting down to a seafood lunch to show confidence in food safety in the wake of the spill.
