BP BLAME: The trial to determine how much more BP and others should pay for the nation's worst offshore oil spill began Monday with the federal government saying the oil giant was mostly to blame for the disaster.
JUDGMENT DAY: Eleven workers died when the rig exploded April 20, 2010, and millions of gallons of oil spilled into the Gulf of Mexico.
DAMAGE DONE: BP capped the well after more than 85 days. It spewed an estimated 172 million gallons of crude into the Gulf, fouling marshes and beaches, killing wildlife and closing vast areas to fishing.
