(CNN) Omarosa Manigault Newman, a former White House aide and reality TV star, claims in her forthcoming book that President Donald Trump’s re-election campaign offered her a lucrative contract in exchange for her signature on a strict non-disclosure agreement after her ouster from the administration last year, according to an excerpt quoted in The Washington Post.

Manigault Newman writes in “Unhinged: An Insider Account of the Trump White House” that she turned down the proposal, which would have barred her from the public criticism she has leveled at Trump since her departure. Lara Trump, a campaign adviser and the President’s daughter-in-law, extended the offer to Manigault Newman shortly after White House chief of staff John Kelly fired her for “serious integrity issues,” according to The Post’s excerpts.
