Senior White House aide Omarosa Manigault Newman, the former star of the initial season of "The Apprentice" and a longtime supporter of President Trump, is leaving the White House next month.

Her resignation is effective Jan. 20, according to White House press secretary Sarah Huckabee Sanders.

Manigault Newman serves as director of communications for the White House Office of Public Liaison.

The White House aide was better known as a reality television star, beginning with the first season of "The Apprentice." She was famous enough to go by one name: Omarosa.

Manigault Newman had served as Trump's chief adviser on African-American issues in the White House. In June, she attacked the Congressional Black Caucus for "showboating" and refusing to meet with President Trump.

Her resignation comes after the White House announced earlier this month that deputy national security adviser Dina Powell will step down from her position early next year.

The two are among several aides expected to leave the administration following Trump's first year in office.
