While the networks are taking some heat for devoting so many resources to the trip, McCain aides have accused Obama of staging an overseas campaign "rally."
McCain gave a different message Thursday, saying that Obama's trip to the two war zones is welcome and long overdue.
On Friday, McCain added that Obama "would be going to a very different Iraq" if the U.S. military had listened to his advice about withdrawing troops.
"There would be chaos. There would be an increase in sectarian violence. There would be widening Iranian influence, and we would be facing disaster — certainly if not disaster, a lost war," he said.
