Bob Woodward says he hadn't planned on releasing audio tapes of his interviews with Donald Trump for his book Rage until CNN reporter Jamie Gangel and the author's wife convinced him.
That turned out to make a huge difference in the book's reception and impact, the veteran author and chronicler of presidential administrations said at an online conference hosted by CNN on Tuesday.
“It's not the same as it is on the page,” Mr Woodward said. “The microphone really is a microscope.”
Ms Gangel worked in tandem with Elsa Walsh, herself an accomplished reporter who helps edit her husband's books, to encourage release of the tapes. They were first given to CNN and The Washington Post.
For a CNN reporter to help push a news source toward a decision that amplifies the impact of a book that is highly critical of Mr Trump may open Ms Gangel to some criticism. CNN is already one of the biggest targets of the president and his supporters.
But it's an important role for journalists to advocate for public release of as much information as possible, said Kathleen Culver, director of the Center for Journalism Ethics at the University of Wisconsin.
“I have no problem with a reporter telling an author that it's in the public interest to see that the tapes are released,” Ms Culver said.
CNN chief Jeff Zucker, who was interviewing Mr Woodward at the conference, also said that “we're all better” for Ms Gangel pressing the point.
“Being honest, the book would have not received the attention, the focus and the kind of ‘oh, it’s all true, we can hear it,' if I did not have those two women ganging up on me,” Mr Woodward said.
Rage is currently number one on Amazon's list of top-selling books and has likely sold hundreds of thousands of copies.
The former Watergate sleuth, with partner Carl Bernstein, was probably already more aware of the power of presidential tapes than any journalist alive.
“We learn about our own business even after 50 years, and for me very dramatically,” he said in an interview after the CNN session.
