DAN RATHER: Dan Rather, CBS News, became sort of all part of my name. A part of my identity.
LEE COWAN: And you have interviewed how many presidents?
RATHER: I'd have to count. Every one since Truman.
COWAN: Gosh!
This is the first time he has appeared on this network since.
RATHER: Without apology or explanation. I miss CBS. I’ve missed it since the day I left there.
COWAN: Even at 92, how and why he left still stings.
RATHER: In the heart of every reporter worthy of the name, Lee, there is a message that news, real news, is what somebody somewhere, particularly somebody in power, doesn't want you to know. That's news.
COWAN: And that's what got him into trouble.
TOM BROKAW: NBC News in depth tonight, the black eye at CBS News. Today, CBS News anchor Dan Rather and the news division…
COWAN: In 2004, Rather filed a report for 60 Minutes 2 that questioned George W. Bush's service record in the Texas Air National Guard.
RATHER: Tonight, we have new documents and new information on the president's military service…
COWAN: But the documents on which Rather and his producer based their reporting could not be later authenticated.
RATHER: It was a mistake. CBS News deeply regrets it. Also, I want to say personally and directly, I'm sorry.
COWAN: Was that the lowest point for you, you think?
RATHER: Of course it was the lowest point. I gave CBS News everything I had. They had smarter, better, more talented people, but they didn't have anybody who worked any harder than I did.
CBS’s Lee Cowan tells us one firehouse within sight of Ground Zero has had its heart cut out.
COWAN: I’d only been at CBS a few years by then, during which Dan Rather had kindly and unexpectedly taken me under his wing and made me feel welcome.
You told me once it's not the question, but it's the follow-up. That that's…
RATHER: Yes. Well, that’s true.
COWAN: That's more important?
RATHER: I hope you’ll not be following up today.
COWAN: Minus the suspenders and his cigars, Rather remains just as I remember him. An intently curious…
RATHER: I'll ring you back in about ten. Thanks.
COWAN: Thoughtful, well-read skeptic who wants nothing more than to wear out his shoe leather chasing the next headline.
