Outgoing presidential aide Omarosa Manigault Newman said she saw things at the White House that made her “very uncomfortable” — as she shot down reports she was fired and physically removed, insisting Thursday that she resigned.

The former “Apprentice” star told “Good Morning America” that reports that the Secret Service escorted her out after she tried to barge into President Trump’s office were false.

“The White House is the most secure place in the world,” she said. “I think you should take the word of the Secret Service over someone who has a personal vendetta.”

She apparently was referring to April Ryan, White House bureau chief for American Urban Radio Networks, who tweeted Wednesday that chief of staff John Kelly “kicked her [Manigault Newman] out with high drama.”

Ryan also reported that Manigault Newman “was very upset and said that she wanted to speak to the president.”

But Manigault Newman threw water on the account by Ryan, with whom she has feuded, though she didn’t mention her name.

“This is the person who has attacked me for the last year, so you know it’s personal,” she said, blaming reports of a dramatic and combative exit on “one individual who has a personal vendetta against me.”

“John Kelly and I had a very straightforward discussion about concerns that I had, issues that I raised and, as a result, I resigned,” Manigault said, adding that they chatted in the secure White House Situation Room.

Manigault Newman was asked about reports that she was displeased with the president’s handling of the rally by white nationalists in Charlottesville, Va., and with his support for Alabama Senate candidate Roy Moore.

“I have to be very careful how I answer this, but there were a lot of things I observed during the last year that I was very unhappy with,” she said.

“But when I have my story to tell as the only African-American woman in this White House, as a senior staff and assistant to the president, I have seen things that have made me uncomfortable, that have upset me, that have affected me deeply and emotionally, that has affected my community and my people.

“And when I can tell my story, it is a profound story that I know the world will want to hear,” she added.

Manigault Newman said her resignation from “this very interesting administration” as communications chief for the Office of the Public Liaison takes effect Jan. 20.

The outgoing aide — who enjoyed unfettered access to the president before Kelly, a retired Marine Corps general, replaced Reince Priebus as Oval Office gatekeeper — said she and other staffers “all had to adjust to his militaristic style.”

“John Kelly brought much-needed order to the West Wing,” she added. “I was very respectful of the process. I had more access than most and people had a problem with that. People had problems with my 14-year relationship with the president.”

A White House official told the Washington Post that Kelly had grown frustrated with Manigault Newman’s caustic and attention-seeking style, which included a misguided appearance in the West Wing in the spring with her bridal party for a photo shoot.

On Thursday, Manigault Newman also denied reports that she had a blow-up with Kelly at a holiday party, saying they were “100 percent false.”

“The assertion that I would do that in front of 600 guests at a Christmas party . . . I have to tell you are completely false,” she said.

If there had been such a fight, she added, “Where are the pictures or videos?”

Manigault Newman also denied that Secret Service agents escorted her off the premises after she set off an alarm at the White House — an assertion the agency backed in a tweet Wednesday.

But she did confirm that the Secret Service deactivated her pass, saying the move was only meant to keep her from accessing more classified areas.

Manigault Newman, a former Democrat, and Trump have known each other since the first season of “The Apprentice,” in 2004, when she emerged as the villainous breakout star.

“Thank you Omarosa for your service! I wish you continued success,” Trump, who once famously fired her on his NBC show, tweeted late Wednesday.

At the White House, she was in charge of outreach to the leaders of HBCUs (historically black colleges and universities), but her day-to-day duties remained ill-defined, which was wearing thin among her colleagues.

When asked if Trump has managed to unify the country, Manigault Newman said: “To unify a nation that was truly divided … to do this in 11 months is almost impossible.

“Did Donald Trump try? I think he tried — in his own way,” she added.
