Omarosa Manigault Newman says she saw things in the White House that she was unhappy with and which made her uncomfortable during her abbreviated tenure in President Donald Trump's "very interesting administration."

"There were a lot of things that I observed during the last year that I was very unhappy with, that I was very uncomfortable with," Manigault Newman said in an interview Thursday with Michael Strahan on ABC's "Good Morning America."

She continued: "I can't expand upon it because I still have to go back and work with these individuals, but when I have a chance to tell my story, Michael, quite a 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 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."

The White House confirmed Wednesday that Manigault Newman had resigned her position as the director of communications for the White House Public Liaison Office, and that the departure would take effect Jan. 20. White House press secretary Sarah Huckabee Sanders said the administration was "grateful for her service" and Trump tweeted his well-wishes later Wednesday, but longtime White House reporter April Ryan suggested on Twitter that Manigault Newman's departure from the administration was less than amicable.

"According to multiple sources Omarosa did not resign," Ryan tweeted. "She was even escorted out of [t]he building and off campus."

Manigault Newman on Thursday confirmed that she resigned the position, but said that reports of how the resignation came to fruition were inaccurate. Manigault Newman clarified that she did not resign publicly and was not escorted from the White House, but instead had a "straightforward discussion" with chief of staff John Kelly in the Situation Room.

The U.S. Secret Service released a statement via Twitter that also rejected reporting that Secret Service personnel physically removed Manigault Newman from the White House premises.

"The Secret Service was not involved in the termination process of Ms Manigault Newman or the escort off of the complex. Our only involvement in this matter was to deactivate the individual's pass which grants access to the complex," the statement said.
