"They respect each other," Borger said.
The last time they worked together was six months ago. During the last budget battle in March, Obama invited Ryan and his Democratic counterpart on the Budget Committee, Rep. Chris Van Hollen, D-Maryland, to lunch. It was the first time Obama and Ryan had sat down together since the presidential race.
Van Hollen said at the time that "their relationship is developing."
One of their first public encounters, however, was mixed. When Obama invited himself to a Republican retreat in Baltimore in 2010, he took questions from the members while the television cameras rolled.
Ryan introduced himself as "a ranking member of the Budget Committee," indicating he wasn't sure the president knew who he was.
After a back and forth about the budget, the president abruptly cut Ryan off, ending the discussion.
Obama later complimented Ryan, saying, "I think Paul Ryan is a pretty sincere guy and has a beautiful family." Obama joked. "And by the way, in case he's going to get a Republican challenge, I didn't mean it. Don't want to hurt you, man."
Fast forward to today. While they have been on different sides of nearly every debate, their relationship is not broken. And in today's Washington, that's saying a lot.
