Transcript for Donald Trump Faces Controversy for 1990s Audio Recording
We'll hear more from her coming up. Donald Trump in the middle of yet another stranger than fiction controversy. Now, this involves newly surfaced audiotapes from the 1990s in which trump allegesly pretends to be someone named John miller who claims to be a publicist for Donald Trump. Well, this John miller person can be heard bragging about trump's business successes, as well as his romantic exploits. Meantime, candidate trump is denying it was him on those audiotapes and ABC's Mary Bruce is here with more. Good morning, Mary. Reporter: Hi, good morning. This is one of the more bizarre twists in a campaign that certainly has been full of them. This morning, Donald Trump is tangled in a new controversy not just for what he reportedly said but for denying he said it at a all. What's your name again. John miller. Mi What is your position. Well, I'm sort of hamming pr because you get so much of it. Reporter: He insists this voice isn't here. He's starting to do tremendously well financially. But it sure sounds like him. Leading tremendously big. Reporter: Presumptive nominee under fire this morning for this 1991 recording reportedly of trump pretending to be his own spokesman bragging about himself. He's somebody that has a lot of options and, frankly, you know, you know he gets called by everybody. He gets called by everybody in the book in terms of women. Reporter: He's heard boasting to a "People" magazine reporter about trump's exploits with women saying he isn't ready to commit to girlfriend Marla maples. He's living with Marla and he's got three other girlfriends. And he's finding off stars like Madonna. She called and wanted to go out with him. Sound familiar? That I can tell you. That I can tell you. That I can tell you, okay. Reporter: According to "The Washington post" trump routinely made calls like this to reporters in the '80s and '90s using various names including John mill sfler people who said he spoke with all the mannerisms that you knew from Donald Trump and you can hear them in this tape. Reporter: A few weeks after the call trump reportedly admitted it was a joke gone awry. But now trump denies it was him. Now, trump also reportedly had a publicist named John baron who bore an uncanny resemblance to trump. Baron the name of his son. I have to imagine the campaign is scrambling. How are they explaining all this? Reporter: Trump is sticking by that denial but in another strange twist "The Washington post" was interviewing trump on the phone and when they asked if he ever employed a John miller, the line suddenly went dead. All right. Mary. As you said, stranger than fiction. Yeah, all right, Mary, thank you. Thank you. Let's bring in lz Granderson to weigh in on this. Lz, good morning, sir. So let me just ask you straight up, do you buy trump's denia here? Of course not. I don't think anyone who's paid attention to his cadence over the past six to eight months can read a transcript and not think it's Donald Trump but him denying this is kind of par for the course. Yeah, it sounds just like him but, of course, he has denied it so how does he walk this back if at all? Well, he doesn't need to walk it back and he's proven through his entire primary season he can say things that aren't true, say things about himself that aren't true, get caught in the untruth and still go forward without it harming his impact on voters and so I don't think he does walk it back. I think he denies, denies, denies and hope we move on to something else. Let me pick up on that point. This is far from the first campaign controversy he has endured and during the primaries nothing seemed to hurt him. However, now that we're basically in the general election do you think this whole teflon Donald thing may change? Well, do you remember the song back in 2000 by the artist shaggy? He had a song called "It wasn't me." It was very, very popular because it was about this guy who was caught cheating on his girlfriend visually looking at him cheating and his excuse is it wasn't me. This is like Donald Trump's entire strategy. Is that when he gets caught, whether he says things that's on his actual website, whether it's an audio recording, whether people to corroborate the fact he lied about something he's continued to say it wasn't me and so I don't expect that to change at all. Lz, you may or may not be aware of this but Paula set out this rule within the staff, anybody who can work in a reference to the 2000 hit "It wasn't me" by reggae artist gets a gold star so congratulations, my friend. Actually and you also happen to tie in a song from Dan's playlist so congratulations, lz. I will be working out to that later today. Much more on this tomorrow morning on "This week" right here on ABC with chief anchor, George stephanopoulos.
