Michael Barbaro at the New York Times got access to a set of audio interviews in 2014 with Donald Trump, his ex-wife Ivana and his kids. 

It was presented in a two-part Run-up podcast. 

It's totally worth a listen with the caveat that some of it is cringe-worthy. 

In some ways Trump seems normal to me, for a guy raised in Queens in the 50s. But not all guys from Queens end up running for President after hosting a hit reality TV show, and all the other things Trump has done. 

Some of the judgements by the commentators are pretty harsh and condescending. But some, especially near the end of the second part, are insightful. 

There hasn't been anything else like this. I wonder if they're going to make the source audio available. It seems like a good idea.
