Obama First?

Obama campaign spokesman Bill Burton just sent out the following statement:

At 8:30 this morning, Senator Obama called Senator McCain to ask him if he would join in issuing a joint statement outlining their shared principles and conditions for the Treasury proposal and urging Congress and the White House to act in a bipartisan manner to pass such a proposal. At 2:30 this afternoon, Senator McCain returned Senator Obama’s call and agreed to join him in issuing such a statement. The two campaigns are currently working together on the details.

So, are they now saying that McCain’s statement is actually a result of their initiative?

UPDATE: A senior Obama campaign official says “the debate is on,” ABC News reports.
