Steve Bannon, President Donald Trump’s chief strategist, is leaving the White House.

Trump’s Chief of Staff John Kelly and Bannon mutually agreed that Friday would be Bannon’s final day, according to White House Press Secretary Sarah Huckabee Sanders.

But Bannon is just the latest of many to leave his role at the White House under Trump.

There have been several high-profile exits during Trump’s early tenure. These are the key officials who have left their positions thus far:

Sally Yates

Acting Attorney General Sally Yates, an Obama appointee, was fired in January after she refused to defend Trump’s controversial travel ban in court. White House Press Secretary Sean Spicer accused her of having “betrayed the Department of Justice” and encouraged others who opposed the executive order to resign.

“I am responsible for ensuring that the positions we take in court remain consistent with this institution’s solemn obligation to always seek justice and stand for what is right,” Yates wrote in a letter at the time.

Mike Flynn

Mike Flynn was asked to resign from his post as National Security Advisor in February, amid revelations that he misled Vice President Mike Pence about the content of his discussions with the Russian Ambassador to the U.S.

Craig Deare

Craig Deare, who Trump had appointed to be director of the National Security Council’s Western Hemisphere division, was fired in February after criticizing the President and other top officials in a private speech.

“I don’t think that any person that is there in order to carry out the President’s agenda should be against the President’s agenda,” Principal deputy press secretary Sarah Sanders told reporters at the time. “It seems pretty silly that you would have somebody that’s not supportive of what you’re trying to accomplish there to carry out that very thing.”

Preet Bharara

Preet Bharara was fired from his post as U.S. Attorney for the Southern District of New York in March, after he refused an order from Attorney General Jeff Sessions seeking the resignation of all 46 Obama-appointed U.S. attorneys.

“I did not resign. Moments ago I was fired. Being the US Attorney in SDNY will forever be the greatest honor of my professional life,” Bharara tweeted at the time.

Angella Reid

Angella Reid, the first woman to hold the post of White House chief usher, was abruptly dismissed from her position this month. The White House said her dismissal was part of the transition of staff at the start of the Trump Administration.

James Comey

Trump fired FBI Director James Comey on May 9, citing his handling of the investigation into Hillary Clinton’s use of a private email server. The dismissal has elicited outrage from members of both parties, and Democrats have called for a special prosecutor to continue investigating potential links between the Trump campaign and the Russian government.

“It is essential that we find new leadership for the FBI that restores public trust and confidence in its vital law enforcement mission,” Trump wrote in his letter to Comey. “I wish you the best of luck in your future endeavors.”

Mike Dubke

Communications Director Mike Dubke resigned on May 18 after just under three months on the job. “The reasons for my departure are personal, but it has been my great honor to serve President Trump and this administration,” Dubke emailed friends, Politico reports.

Sean Spicer

Sean Spicer abruptly resigned as the White House press secretary on July 21. By that time Spicer had stepped back from most day-to-day press briefings and was planning on a larger role in the communications shop, but he thought his position was diminished by Anthony Scaramucci’s hire and resigned instead.

Reince Priebus

Trump bluntly tweeted on July 28 that he had replaced Chief of Staff Priebus with Secretary of Homeland Security John Kelly. Trump had been increasingly directing his anger at Priebus after the failure of the Republican health care repeal bill, other stalled legislative hopes and dramatic infighting in the White House leaking to the press. Priebus also had an enemy in new White House communications director Scaramucci, who had threatened to push him out.

Anthony Scaramucci

Scaramucci lasted just ten days as White House communications director. “Anthony Scaramucci will be leaving his role as White House Communications Director,” White House Press Secretary Sarah Huckabee Sanders said in a statement on July 31. “Mr. Scaramucci felt it was best to give Chief of Staff John Kelly a clean slate and the ability to build his own team. We wish him all the best.”

Scaramucci’s White House tenure may have been brief, but it was dramatic. The New Yorker published an explosive account of a conversation reporter Ryan Lizza had with Scaramucci at the end of July, in which Scaramucci said that White House Chief of Staff Reince Priebus had “c–k-blocked” him for six months and, “I’m not Steve Bannon, I’m not trying to suck my own c–k.”

Steve Bannon

News broke on Aug. 18 that Chief Strategist Steve Bannon would be leaving the White House.

Trump’s Chief of Staff John Kelly and Bannon both agreed that Friday would be Bannon’s final day in the role, according to White House Press Secretary Sarah Huckabee Sanders. “We are grateful for his service and wish him the best,” she said in a statement. Bannon’s ouster came after weeks of controversy and staff changes at the White House, and after he apparently contradicted the president on North Korea strategy in an interview earlier in the week.

Tom Price

Health and Human Services Secretary Tom Price resigned from his position on Sept. 29, following a scandal over his use of costly private planes.

Price spent more than $1 million on private jets to travel to Europe, Asia and around the U.S. He apologized for using taxpayer funds to pay for his work trips a day before announcing his resignation, saying he would pay back the Treasury Department for the costs he incurred. The $51,887.31 he promised to pay covers merely a fraction of what taxpayers doled out.

Price’s use of private planes embarrassed the White House and angered congressional Republicans. His resignation came hours after Trump announced he would make a decision by the end of Friday on firing Price.
