Just read the WaPo article about Woodward's book. It sounds like a doozy - Trumpy will not be best pleased.
And as for Princess Perfect...
The president’s family members, while sometimes touted as his key advisers by other Trump chroniclers, are minor players in Woodward’s account, popping up occasionally in the West Wing and vexing adversaries.
Woodward recounts an expletive-laden altercation between Ivanka Trump, the president’s eldest daughter and senior adviser, and Stephen K. Bannon, the former chief White House strategist.
“You’re a goddamn staffer!” Bannon screamed at her, telling her that she had to work through Priebus like other aides. “You walk around this place and act like you’re in charge, and you’re not. You’re on staff!”
Ivanka Trump, who had special access to the president and worked around Priebus, replied: “I’m not a staffer! I’ll never be a staffer. I’m the first daughter.”
