"Thank you very much, Mr. Secretary," McCain addressed Kerry. Although much of the speculation of who might succeed Secretary of State Hillary Clinton includes Ambassador Susan Rice, the Massachusetts Democrat is also thought to be on any short list for the post.
Returning to the podium next, Kerry began, "Thank you very much, Mr. President." McCain, a Republican from Arizona, was the GOP nominee for the Oval Office in 2008.
"This is what happens when you get two losers up here, folks. We're just having fun," Kerry continued. He was the Democratic presidential nominee in 2004.
