The president's speech: A breakdown
Quotes of note
-- "Make no mistake: We will fight this spill with everything we've got for as long it takes. We will make BP pay for the damage their company has caused. And we will do whatever's necessary to help the Gulf Coast and its people recover from this tragedy."
-- "Because there has never been a leak of this size at this depth, stopping it has tested the limits of human technology."
-- "Already, this oil spill is the worst environmental disaster America has ever faced. And unlike an earthquake or a hurricane, it is not a single event that does its damage in a matter of minutes or days. The millions of gallons of oil that have spilled into the Gulf of Mexico are more like an epidemic, one that we will be fighting for months and even years."
-- "Now, a mobilization of this speed and magnitude will never be perfect, and new challenges will always arise. I saw and heard evidence of that during this trip. So if something isn't working, we want to hear about it. If there are problems in the operation, we will fix them"
