Donald Trump Jr. and Ivanka Trump tried to divert inheritance money away from half-sister Tiffany Trump, according to a tape of a conversation President Trump had on "The Howard Stern Show" published Monday.

"Do your older children get nervous every time you have another child?" Stern asked Trump in December 2005 when he appeared as a guest on the controversial radio show.

In response, the president relayed a discussion he had with a "very rich" friend of his, per the 15 hours of recordings obtained by Newsweek.

"And he said how his children hate the new children coming along and everything else," Trump said. "I said, 'Yeah, because every time you have a child, it's 20 percent less to the people [Inaudible].'"

Stern returned to the subject of inheritance later in the segment and asked the president whether his eldest children, Donald Jr. and Ivanka, were "trying to bump off a child."

"Is there any truth to that? [Inaudible] Tiffany?" Stern pressed.

"Yes," Trump replied after first trying to dodge the question.

Trump has three children with first wife, Ivana Zelníčková: Donald Jr., Ivanka and Eric. Tiffany is the product of his second marriage to Marla Maples.

The tapes, dating from 1993 to 2015, also record Trump talking about "making love to Melania during pregnancy" and groping her in public, as well as Ivanka "looks down" on him.
