TRUMP: She's beautiful.
STERN: Can I say this? A piece of ass?
TRUMP: Yeah.
Think about the fact that this interaction was just "favourited" by Ivanka's Twitter account, and shudder away.
While there was speculation that it may have been a hoax, some users responded to Kaczynski's tweet with similar screenshots.
The CNN reporter also noted that the tweet had been unliked about 30 minutes after he tweeted it.
Asource close to Ivanka Trump later told Us Weekly "a simple mistake was made by a staff member" who liked the post.
For what it's worth, that's not the only time Donald Trump has made a creepy reference to his daughter.
In a 2003 Stern interview, he said Ivanka has "got the best body".
Likewise, during an appearance on ABC'S "The View" in 2006, he infamously said that if Ivanka wasn't his daughter he would be dating her.
In an interview with Rolling Stone last year, he made a similar comment: "Yeah, she's really something, and what a beauty, that one. If I weren't happily married and, ya know, her father...'
The news comes shortly after footage leaked of the Republican candidate bragging in 2005 that he could "grab" women "by the p***y" and get away with it due to his celebrity status.
The recording received global condemnation, with some Republican politicians calling on Trump to resign from the campaign.
