Hitting out at the former aide after the release of the recording, Mr Trump tweeted: "Wacky Omarosa, who got fired 3 times on the Apprentice, now got fired for the last time". And yet, here she has an opportunity to confront Trump in the immediate aftermath of her firing, and Omarosa sounds as if she wants to get Trump to get her job back for her.
Former adviser Omarosa Manigault Newman surreptitiously recorded a conversation that she says took place in the Situation Room.
The latest recording Manigault made public is allegedly of a phone call she shared with the president after her firing. She was vicious, but not smart.
"Nasty to people and would constantly miss meetings and work", the president continued. "I told [Mr Kelly] to try working it out, if possible, because she only said GREAT things about me - until she got fired!" She said Kelly was running the administration.
Trump tweeted a scathing criticism of his former top-level aide just as her book-promoting media tour was gaining steam, all but guaranteeing the kind of made-for-cable feud that made them both reality TV stars and ultimately brought them to the White House.
The audio release comes a day after Manigault Newman released audio she said was of her firing by Kelly inside the White House Situation Room. I just saw in the news you're thinking about leaving.
"They continue to deceive this nation by how mentally declined he is, about how hard it is for him to process complex information, how he is not engaged in some of the most important decisions that impacts our country", she said on NBC.
NBC News said it does not know what was heard before or after the exchange between the two. She said she had recorded the conversation because otherwise no one would believe her.
Here's a montage of her whining about how America is doomed at the hands of Trump mashed up with footage of her gleefully declaring a year earlier that everyone who criticized Trump was going to have to eat crow.More news: Parker Solar Probe launches Saturday on mission to 'touch' the sun

Asked during a photo-op at his New Jersey golf club Saturday about the developments, Trump responded, "Low-life".
But the incident isn't in her book because she didn't hear the tape until after the book was published.
She told NBC's Today show there were "multiple tapes" and warned that there were more to come.
"It's actually really sad to watch him become unhinged", she added.
In a statement Friday, White House press secretary Sarah Huckabee Sanders described the book as "riddled with lies and false accusations".
"I was complicit with this White House deceiving this nation", she said.
When asked if Trump was aware of Kelly's decision, the West Wing leader told Manigault-Newman, "Don't do - let's not go down the road".
It's unclear whether Trump really didn't know about the firing, or actually did and just wasn't fearless enough to admit it.
"Whether it's thirty pieces of silver or a seven-figure book advance for you, your publicist, your ghost-writers and others, all that's changed is this book deal and her being fired, so I think he probably feels very betrayed", Conway said. The AP has independently listened to the recording of Kelly and Manigault Newman. She claims to have heard a tape of Trump using the racial slur after she wrote the book. I don't love you leaving at all.
