Bob Schieffer: "This is what I always wanted to be"

It was business as usual Friday for CBS News' Bob Schieffer. The longtime moderator of "Face the Nation"was in Nashville, Tenn., to interview Jeb Bush for this Sunday's broadcast -- Schieffer's last.

"Today marks my official debut, as it were, as moderator of 'Face the Nation,'" said Schieffer in 1991. "Our aim is going to be very simple here: to find interesting people from all segments of American life who have something to say, and give them a chance to say it."

Schieffer did just that for the last 24 years and this Sunday, he'll do it one last time before entering a well-deserved retirement. His CBS News colleague Charlie Rose spoke with him on Friday about his storied career.

"This is what I always wanted to be when I was a little boy," said Schieffer. "It wouldn't have dawned on me back in those days that I'd get to talk to all the people I talked to and cover the stories I got to cover ."

Watch the video above to see Schieffer's chat with Rose, including what Schieffer finds to be the "great allure of journalism."
