In a speech today, President Obama stated that he "will do whatever it takes for as long as it takes" to deal with the oil spill. He further promises that "We're going to fight back with everything that we've got."

President Obama is scheduled to address the nation tonight to lay out plans for dealing with the BP oil disaster in the Gulf of Mexico.

So how much oil has leaked into the gulf?

No one can say for certain how much oil is leaking into the Gulf of Mexico, however, some experts are now estimating that between 1 million and 2 million barrels. That converts to bewteen 42 million and 84 million gallons of oil.  The lowest estimate is nearly four times the size of the 1989 Exxon Valdez spill.
