Update Dec 13, 2017 8:44 PM EST: Manigault Newman's departure came after a dust-up with White House Chief of Staff John Kelly, according to White House correspondent April Ryan, who described a "vulgar" exchange on CNN between Manigault Newman and Kelly when the former reality TV star was barred from the president's residence Tuesday night.
The Wall Street Journal confirmed Ryan's account, although the Secret Service denied its agents were the ones that "physically" removed Manigault Newman from the White House.
Original report: White House press secretary Sarah Huckabee Sanders confirmed Manigault Newman's resignation is effective Jan. 20, 2018, on the one-year anniversary of Trump's inauguration.
"We wish her the best in future endeavors and are grateful for her service," Huckabee Sanders said.
Contrary to the White House statement, sources told reporter April Ryan and The New York Times's Yamichi Alcindor that Manigault Newman did not resign. Instead, sources said she was fired Tuesday.
Manigault Newman serves as the director of communications for the Office of Public Liaison. She previously served as Trump's chief adviser on African-American issues in the White House, according to The Hill.
Manigault Newman was one of Trump's most prominent African-American supporters. The president thanked her in February during an event for African-American History Month, saying that she was "very special."
"I want to thank my television star over here," Trump said at the Feb. 1 event, referencing Manigault Newman's time on his business reality show competition, "The Apprentice."
"Omarosa is actually a very nice person. Nobody knows that, but I don’t want to destroy her reputation. She is a very good person and she’s been helpful right from the beginning of the campaign. And I appreciate it. I really do."
Her exit comes amid an anticipated round of Trump administration official departures headed into the New Year, according to The Associated Press. Last week, White House officials said deputy national security adviser Dina Powell her post will be leaving early next year.
