Markets fall after Greece's credit rating downgraded

Senate Democrats sent a letter to Hayward on Monday asking for the creation of a $20 billion escrow fund to ensure there is enough money to pay for the damage caused by the oil spill. 

The company's board met today to discuss a planned dividend but no information was expected out of those meetings until Wednesday, when BP CEO Tony Hayward and Carl-Henric Svanberg, BP's chairman of the board, are scheduled to meet with Obama at the White House. 

Hayward will testify on Capitol Hill before several committees on Thursday. 

Obama made his fourth visit to the Gulf Coast on Monday and will address the nation from the Oval Office on Tuesday night.
