It's something of a turnaround from 2007 and 2008, as the two raced through Iowa and New Hampshire and onward. In increasingly bracing language, the two excoriated the other. At one point, a visibly angry Clinton seethed, "Shame on you, Barack Obama."
Obama now jokes about the rivalry.
"Made for tough debates, by the way, because we could never figure out what we were different on," the president said.
Both acknowledged disagreements continue but said they had common goals.
"Are there going to be differences? Yeah. Deep differences? Of course," Clinton said. "You had a lot of strong-willed, -minded people. But the president deserves our best judgment, our advice and then he deserves us to stand with him and to execute."
