This isn't the first time people have made comments about how Mr Trump acts around his daughter. When asked about Ivanka in a 2015 interview with Rolling Stone, Mr Trump said: “Yeah, she’s really something, and what a beauty, that one. If I weren't happily married and, ya know, her father..."
Perhaps the most shocking moment was during an interview on The Vine in 2006, when Donald and Ivanka were together promoting season three of The Apprentice.
The host asked Mr Trump how he would react if Ivanka posed for Playboy magazine. He said:
It would be really disappointing — not really — but it would depend on what's inside the magazine.
I don't think Ivanka would do that, although she does have a very nice figure. I've said if Ivanka weren't my daughter, perhaps I'd be dating her.
Isn’t that terrible? How terrible? Is that terrible?
