Ivanka Trump once told a gathering of friends and acquaintances she had never seen "a mulatto cock," BuzzFeed chief executive Jonah Peretti alleged Wednesday.

"Surprised Ivanka would be shocked by lewd language," Peretti tweeted. I met her once & she casually said: 'I've never seen a mulatto cock, but I'd like to."

Reached by phone, Peretti said he wrote the tweet in an airport lounge in Burbank, California, after having read a BuzzFeed News report about the daughter of the Republican presidential nominee reacting to a 2005 tape of him making lewd remarks about grabbing women's genitals.

"That's not language consistent with any conversation I've ever had with him, certainly, or any conversation I've overheard," she said at Fortune's Most Powerful Women Summit. "So it was a bit jarring for me to hear."

Peretti said the encounter with Ivanka occurred at a Manhattan dive bar called Tropical some about 10 years ago with roughly five other people present.

"She was saying how she first said she had never seen an uncircumcised cock and then she said, 'I've never seen a mulatto cock. There's lots of cocks I've never seen,' or something like that," Peretti said.

"Of course, it was memorable just because of the use of the lewd language and racist language. It was also memorable being in the environment of being... in New York, sometimes liberal and progressive people make comments meant as jokes and not necessarily earnest. I didn't know how to take it."

Peretti said he "sat" on the quote, not revealing it until now, because it was "personal."

"I have conversations with people all the time and I never share things said in private. I only shared this because I read the article and it felt like that experience was relevant," he said.

Spokespersons for the Trump campaign and Ivanka Trump did not immediately respond to requests for comment.
