Omarosa opens up about Trump and the White House in new book 'Unhinged'

Former White House aide Omarosa Manigault-Newman, known for her role on "The Apprentice," is telling all about working for mentor and colleague Donald Trump in her new book "Unhinged."

The book dishes on working in the Trump administration. Manigault-Newman was fired from the White House in January 2018.

In a series of interviews on NBC, Manigault Newman revealed two audio recordings from her time at the White House, including portions of a recording of her firing by Kelly, which she says occurred in the high-security Situation Room, and a phone call with Trump after she was fired.

She has made clear that she plans to continue selectively releasing the pieces of evidence if President Donald Trump and his associates continue to attack her credibility and challenge the claims in her book.

She's already dribbled out audio recordings of conversations, and video clips, texts or email could follow, according to the person who described what Manigault Newman has called a multimedia "treasure trove." The person was not authorized to discuss the issue publicly and asked for anonymity, The Associated Press reports.

"I will not be silenced. I will not be intimidated. I'm not going to be bullied by Donald Trump," the former Trump aide told The Associated Press this week as she seemed to dismiss a threat from Trump's campaign.

Manigault-Newman tells FOX 5's Steve Chenevey that after their 15-year-relationship, she says she started to notice Trump's decline. "So many different moments throughout that first year in the white house, um, you know it started to sour once he thought Frederick Douglass was still alive," she said.

She defends her taping meetings and releasing them, citing their history as reasoning for coming out with the hairy details.

"You know, I was completely disappointed. Donald Trump has reduced the presidency to playground name calling. He has no respect for the office of the highest office of this land, and to be on the receiving end as you've so eloquently pointed out after 15 years, to call me the worst name that you can call a woman," she says.

"If he says that publicly, just imagine the things that he says about me privately. Its not unacceptable for the leader of this country to be behave that way and that's why he basically completely backs up my statement about him being unhinged."

She spoke to the AP hours after Trump's campaign announced it was filing an arbitration action against her alleging she'd violated a signed agreement with the campaign that prohibits her from disclosing confidential information.

She told PBS in a separate interview this week: "I have a significant amount, in fact, a treasure trove, of multimedia backup for everything that's not only in "Unhinged," but everything that I assert about Donald Trump."

Manigault Newman claims Trump officials offered her a job on the campaign as a way of silencing her, after she was fired from the White House. She's accused Trump of being racist and suffering from a mental decline.

Manigault Newman says she has more recordings. Asked on MSNBC's "Hardball" if special counsel Robert Mueller -- investigating possible coordination between the Trump campaign and Russia -- would be interested in any of them, she said, "If his office calls again, anything they want, I'll share.

She also alleges that Trump allies tried to buy her silence after she left the White House, offering her $15,000 a month to accept a "senior position" on his 2020 re-election campaign along with a stringent nondisclosure agreement.
