Stern considers Trump a friend who has repeatedly been a guest on his radio program over the years.
"Why don't I play all the tapes? I have to tell you why: I feel Donald Trump did the show in an effort to be entertaining and have fun with us and I feel like it would be a betrayal to any of our guests if I sat there and played them now (when) people are attacking him," said Stern, according to The Washington Post and Billboard.
Trump comments to Stern have already been a factor in the election reporting —including giving Stern his permission to call his daughter Ivanka a "piece of a--" in 2006, boasting about walking in on undressed contestants backstage at his beauty pageants during a 2005 chat, and an admission of infidelity (in 1990) during a 2004 conversation.

When the Republican candidate started winning primaries last year, Trump called Stern at home. Stern recalled asking, "Why are you doing this?' Why would a guy with billions of dollars (run for president)? ... Don't you know what they're gonna do to you? Don't you know they're gonna open up everything?"
Still, Stern — no stranger to stirring up controversy talking about sex and women's bodies on his show – drew a line at the lewd language used in Trump's leakedAccess Hollywood tape.
"But this idea of 'locker room talk' ... all the times I've been around guys — and believe me when I'm around guys, 85% of the times you're talking about p----. But I have never been in the room when someone has said, 'Grab them by the p----,' " said Stern, mimicking comments used by Trump in 2005 while on a bus with Billy Bush.
"No one's ever advocated going that step where you get a little bit, 'Hey I'm going to invade someone's space.' ... A lot of (locker room banter is) real kind of desperate talk. The reason it's in a locker room is because no one's proud of it."
