BP has tried several methods to stop or contain the oil gushing into the Gulf of Mexico, but 36 days after it began, all attempts by the company to cap the spill have failed.
So, what's happening today?
The company discussedÂ its latest attempt to contain the oil, a maneuver called a "top kill" that it plans to implement Wednesday.
Oil rig owner Transocean plans to hold a memorial service today to honor 11 workers who have been missing since the rig exploded.
What can we expect to happen next?
BP briefered on the "top kill," which including pumping thick, viscous fluid twice the density of water into the site of the leak to stop the flow so the well can then be sealed with cement. The top kill procedure has worked on above-ground oil wells in the Middle East but has never been tested 5,000 feet underwater. Still not sure how the "top kill" procedure works?

Who is leading the charge?
BP has been working over the past month to find a way to contain the oil, and as time goes on, some people are wondering just how much can the government do to help - and how much of the problem is for BP to solve.
CNN's Tom Cohen reports that legally, President Obama can effectively fire BP and have the federal government take over efforts to stop the Gulf of Mexico oil spill. The question is whether that would help the situation.
Why are the EPA and BP fighting about dispersants?
The federal government has instructed BP to scale back its use of oil dispersants in the Gulf of Mexico.
EPA Administrator Lisa Jackson said that dispersants are breaking up much of the oil but that "we are making environmental tradeoffs" and are "deeply concerned" about potential side effects.
CNN's Ed Lavandera digs deeper into the issue.
Backlash against BP
Public patience is wearing thin in Louisiana, where fishing is a $2.4 billion industry, and the continued threat to seafood means there may be tough times again.
"BP We Want Our Beach Back" read one of many signs posted in Grand Isle, Louisiana.
Louisiana Gov. Bobby Jindal has publicly expressed frustrations at the red tape hampering the oil cleanup in his state.
And on a major publicity front, BP is finding rough waters too: A fake BP public relations Twitter account is mocking the cleanup efforts and gaining a lot of attention. With posts from the account @BPGlobalPR directing people not to clean up the shores because the oil is BP's property and they will be sued, and one saying "the ocean looks just a bit slimmer today. Dressing it in black really did the trick! #bpcares" it is clear that frustration is growing against the company in some form.
And while it seems to be painfully obvious that the Twitter account is fake, it has more than double the number of followers of BP's actual Twitter account (@BP_America).
