Even now there is no evidence that anyone involved in the Nixon operation was going to threaten us.

I have gone on the air and announced my telephone number at the Washington Post. I go into the night, talking to people, looking for things. The great dreaded thing every reporter lives with is what you don't know. The source you didn't go to. The phone call you didn't return.

The central dilemma in journalism is that you don't know what you don't know.

I recently read some of the transcripts of Nixon's Watergate tapes, and they spent hours trying to figure out who was leaking and providing information to Carl and myself.

I don't think it's useful for somebody to argue with reviews.

They need to review this secret world. We have an incredibly powerful government that gets on automatic pilot.

Some newspapers have a hands-off policy on favored politicians. But it's generally very small newspapers or local TV stations.
