Here are the notable firings and resignations of the Trump administration, starting with the most recent departure:

Dec. 13: Omarosa Manigault Newman

Newman, who rose to notoriety when she was on The Apprentice with Trump, was left her job in the White House's Office of Public Liaison. She later denied that she had been fired or escorted from White House grounds, though the Secret Service did say it terminated her access.

Dec. 8: Dina Powell

Trump's deputy national security adviser, who was a driving force behind the president's Middle East policy, plans to depart the administration early next year, the White House announced in December.

Sept. 29: Tom Price

The Health and Human Services secretary resigned after revelations that he had racked up around $400,000 in private flights while traveling on official business.

Aug. 25: Sebastian Gorka

When the controversial counterterrorism adviser stepped down, he said Trump's populist campaign agenda had been hijacked by establishment figures.

Aug. 18: Steve Bannon

The chief strategist, who had a turbulent time at the White House, left his post after pressure to remove him from his post following violent clashes in Charlottesville, Va. For his part, Bannon said he resigned two weeks prior.

July 31: Anthony Scaramucci

The controversial communications director stepped down after 11 days on the job, the same day John Kelly took over as chief of staff.

July 28: Reince Priebus

In his six-month tenure, marked by staff infighting and political reversals, the chief of staff was often a target of Trump loyalists who said he had failed to help the president win congressional legislation.

July 25: Michael Short

The senior assistant press secretary, brought on by Priebus, resigned after Scaramucci said he was going to fire him for allegedly leaking to the press.

July 21: Sean Spicer

The press secretary's tumultuous tenure, marked by standoffs with the press, culminated in his resignation when Trump went against his advice to hire Scaramucci as his new communications director.

July 6: Walter Shaub

The director of the Office of Government Ethics clashed repeatedly with the president before announcing his resignation.

May 18: Mike Dubke

Trump's first communications director did not work on the Trump campaign and did not know Trump before his hire. He handed in his resignation after three months on the job.

May 9: James Comey

The White House initially said the FBI director's firing was based on the Justice Department's recommendation, over his handling of the Clinton email probe. Since then, Trump has said he had considered firing Comey even without that recommendation and has said the Russia investigation was on his mind when he made the decision.

May 5: Angella Reid

The chief usher was fired for unclear reasons; it is unusual for a chief usher to be dismissed and they typically hold their positions for several years and over a number of administrations.

Feb. 13: Michael Flynn

The national security adviser was mired in controversy after news reports surfaced that he had misled officials, including Vice President Pence, about his communications with Russian Ambassador Sergey Kislyak. He resigned shortly afterward.

Jan. 30: Sally Yates

The acting attorney general, a holdover from the Obama administration, was dismissed after she refused to defend the first iteration of Trump's travel ban on citizens from seven Muslim-majority countries.
