President Barack Obama will hold a news conference at the White House on Thursday, a day before his second trip to the Gulf of Mexico region and amid growing criticism of the administration's response to the month-long oil spill.
Meantime, the oil company at the center of the storm, BP, is still running tests and expected to decide Wednesday morning if it will go ahead with an effort to choke off its oil gusher with a process known as a "top kill."
Chief Executive Tony Hayward said on NBC's TODAY that if he gives the green light, "it will be a day or two before we can have certainty that it's worked."
