Omarosa was later appointed as the vice-chair of the National Diversity Coalition for Trump.

She landed a formal role with the Trump campaign as its director of African-American outreach in July 2015, and eventually became a member of his transition team after Trump was elected president.

During a testy exchange with Omarosa near the Oval Office, Ryan said she felt "physically intimidated" by her.

Ryan accused Omarosa of saying she was included in supposed White House "dossiers" of negative information on several journalists.

"She stood right in my face like she was going to hit me," Ryan said in The Washington Post.

Omarosa denied that she had threatened Ryan and also accused her of hurling insults.

Trump appointed the former four-star Marine Corps General John Kelly to be White House chief of staff, which ultimately signaled the beginning of Omarosa's departure.

In a White House that was teeming with embarrassing leaks, Kelly began regulating the staffers's facetime with the president and attempted to limit the scores of unflattering news reports.

Omarosa's reportedly unfettered access to Trump was curtailed and that set the stage for a more explosive encounter in the weeks ahead.

Kelly fired Omarosa in January.

Multiple news reports recounted a less-than-amicable departure, with some suggesting she was forcibly escorted off the White House grounds.

April Ryan, the reporter from American Urban Radio Networks who previously had an altercation with her, said sources told her that Omarosa used vulgar language towards Kelly and "tried to get in" Trump's residence.

At the time, Omarosa disputed reports that she was fired.

However, in a secretly recorded conversation between Omarosa and Kelly inside the Situation Room, the chief of staff indicated she was being let go. Omarosa later described the conversation as a veiled threat that if she did not leave, her future career might be in jeopardy.

In another audio file Omarosa later released, Trump suggested he was unaware of her firing, saying "I don't love you leaving at all."

Omarosa conducted several interviews and made reality TV show appearances after she was booted from the White House.

In July, publishing company Gallery Books announced she would be releasing the tell-all book, "Unhinged: An Insider's Account of the White House," in August.

"Omarosa is finally ready to share her side of the story in this explosive, jaw-dropping account," the company said.

In the days leading up to her book's release, Omarosa teased several audio tapes of her secretly recorded conversations with Trump's campaign and White House staffers.

She also made several explosive claims about Trump, including an assertion that she heard Trump say the N-word "multiple times" in reference to Kwame Jackson, a black contestant on NBC's "The Apprentice."

"It sounded as if he used it every day," Omarosa told MSNBC host Chris Matthews of the N-word. "It rolled off his mouth."

The White House and Trump's surrogates countered Omarosa's claims with their own media blitz.

On Twitter, Trump said there were "NO TAPES" of him using a racial slur and described his former apprentice as "Wacky and Deranged," "lowlife," "crazed," and "that dog."

Other Trump associates who were implicated in the secret recordings took swings at their former colleague, calling her "a dog with a bone" and downplayed her claims of having heard a recording of Trump saying racially insensitive remarks.

Katrina Pierson, a Trump campaign official, admitted Omarosa mentioned the tape's alleged existence in multiple conversations, but said she was forced to "placate" her "obsession" by looking into the claim.

Former campaign aide and regional director at the Department of Housing and Urban Development Lynne Patton echoed Pierson's remarks.

"There were a lot of times that we talked about this tape because Omarosa was literally obsessed with it," Patton said on CNN. "She brought it up constantly. It's clear now that the reason why she did was because she was surreptitiously recording us."

Trump's presidential campaign also filed arbitration proceedings in light of her book, claiming she breached a nondisclosure agreement for her role in the White House.

Following the White House's denials, Omarosa stood her ground, saying she "will not be silenced" by Trump.

"I will not be intimidated," Omarosa told The Associated Press. "I'm not going to be bullied by Donald Trump."
