Howard Stern said he won't air old interviews with Donald Trump that feature the now GOP presidential nominee discussing his sexual exploits.

"I feel Donald Trump did the show in an effort to be entertaining and have fun with us," Stern said. "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."

Stern noted that his conversations with Trump were broadcast and not "done in private like the Billy Bush tapes."

"I knew I had a guy who loved to talk about sex," Stern said. "I had a guy who loved to evaluate women on a scale of 1 to 10. These are avenues I went down because I knew it would entertain the audience."

In past interviews with the shock jock, Trump has given Stern permission to call daughter Ivanka Trump a "piece of (expletive)," boasted about walking in on undressed contestants at his beauty pageants, bragged that he could have had sex with Diana, princess of Wales, and admitted to cheating on ex-wife Ivana Trump.
