Author of Kushner Inc Vicky Ward has claimed Ivanka believes she will eventually become President. Ms Ward said Donald Trump's "greatest weakness" is his daughter after conducting 220 interviews, Harpers Bazaar reported. The book accused the First Daughter and her husband Jared Kushner of being “power-hungry”.
A source told Ms Ward: “The two of them see this as a networking opportunity.”
The pair currently hold senior roles in the Trump administration.
Gary Cohn Trump’s former economic advisor said: “She thinks she’s going to be President of the United States.
“She thinks this is like the Kennedys, the Bushes, and now the Trumps."
Ms Ward also looked into the relationship between Ivanka and her father.
She wrote their relationship is “more complex than anyone could fathom".
She also accused Trump of embarrassing Ivanka in front of senior staff, as "she needed to be publicly reminded who's in charge".
Ms Ward has previously claimed the two are a “threat” to the US.
In response to the remarks, White House press secretary Sarah Sanders released a statement calling the quotes fictitious.
She said: “It's sad, but not surprising, the media would spend time promoting a book based on shady anonymous sources and false information instead of all the incredible work Jared and Ivanka are doing for the country.”
A spokesman for Mr Kushner, Peter Mirijanian, also dismissed the revelations as fictitious.
Mr Mirijanian said: “Every point that Ms Ward mentioned in what she called her 'fact checking' stage was entirely false.
“It seems she has written a book of fiction rather than any serious attempt to get the facts.”
