Yes but no. What happens is, an actual journalist does their job and people get up in arms. Commercial media will slowly start to cover the topic. In this case, the audio will come out and the world is aghast. Commercial media will interview Trump or his cabinet and ask "how do you respond to the rumors of this audio?" As if the audio isn't real and as if we've not all heard it. Like it's an anomalous thing that he's accused of like a case of he said-she said between rival politicians. Like it's not obviously real and factual. That's how it gets covered.

i was thinking broadcast media. I suppose a book is media, but does it reach a broad audience?

I've heard Chris Christie tell an anecdote about the 2016 campaign a few times:

To hear him tell it, Christie was watching the live interview where Trump said McCain wasn't a war hero because heroes don't get captured. When Christie heard that line, he picked up the phone and called Jeb Bush, and said, "Looks like it's down to just you and me. Do you want to be my VP?"

Because any other candidate at any point in modern history dismissing a veteran like that would've been immediately unelectable.
