AP source: Omarosa also has video

WASHINGTON -- It's not just audiotapes.

Omarosa Manigault Newman has a stash of video, emails, text messages and other documentation supporting the claims in her tell-all book about her time in the Trump White House, a person with direct knowledge of the records told The Associated Press.

Manigault Newman has made clear 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, "Unhinged." 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.

"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. 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 prohibiting 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 claimed 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.

The White House has countered by branding Manigault Newman as a disgruntled former staffer with credibility issues who is now trying to profit from a book based on false attacks against an individual she has called a mentor and has admired for more than a decade.

Trump has also lashed out at Manigault Newman, calling her a "lowlife," "wacky and deranged" and a "dog."

Simon & Schuster this week also dismissed threatened legal action from Trump's campaign. A campaign attorney told Simon & Schuster in a letter "Unhinged" violated Manigault Newman's confidentiality agreement, but the publisher responded it was acting "well within" its rights.

"Unhinged" has spent the past few days at No. 2 on Amazon.com's best-seller list, trailing only Rachel Hollis' lifestyle book "Girl, Wash Your Face."
