On Tuesday, after returning from the Gulf, President Obama will deliver a prime-time address from the Oval Office:

“We’re at a kind of inflection point in this saga, because we now know that, what essentially what we can do and what we can’t do, in terms of collecting oil, and what lies ahead in the next few months,” senior adviser David Axelrod said on NBC’s “Meet the Press. “And he wants to lay out the steps that we’re going to take from here to get through this, through this crisis.”

In a preview interview, Obama tells Roger Simon that the BP oil spill “echoes 9/11.”

“In the same way that our view of our vulnerabilities and our foreign policy was shaped profoundly by 9/11,” the president said in an Oval Office interview on Friday, “I think this disaster is going to shape how we think about the environment and energy for many years to come.”
