President Donald Trump called former White House adviser Omarosa Manigault Newman a “lowlife” Saturday.

Trump was responding to a question from New York Times reporter Maggie Haberman about Manigault Newman’s tell-all memoir that was announced this week.

When Haberman asked Trump if he felt betrayed by Omarosa, the president laughed, cupped his hand around his mouth, and said, “Lowlife. She’s a lowlife.”

Trump was in front of the press for an event with bikers as part of his working vacation this week at Trump National Golf Club in Bedminster, New Jersey.

Reports of the bombshell allegations in the book against Trump caught fire this week, including her calling him a "racist," "misogynist," and a "bigot" alongside accounts of him using a racial slur on the set of The Apprentice, and eating a piece of paper in the Oval Office.

But Manigault Newman has already contradicted that claim - though she said in the book that she was informed by a source that Trump used a racial slur, she told NPR in an interview Friday that she had heard a recording of the comments herself.

Manigault Newman also wrote in the book she was offered $15,000 a month contract to sign a nondisclosure agreement after she was fired from the White House last year, which she said she turned down.

Manigault Newman also reportedly secretly recorded Trump, then used those recordings as leverage while shopping her book.

White House press secretary Sarah Sanders released a statement Friday afternoon, in which she said the book is "riddled with lies and false accusations."

"It's sad that a disgruntled former White House employee is trying to profit off these false attacks, and even worse that the media would now give her a platform, after not taking her seriously when she had only positive things to say about the President during her time in the administration," Sanders said.

Manigault Newman worked in the White House for nearly a year as an assistant to the president and the director of communications for the Office of Public Liaison.

"Unhinged: An Insider's Account of the Trump White House" is set to be published by Gallery Books on August 14.
