A list of officials who have left the Trump administration

A running list of who has left the White House and administration.

— -- Donald Trump's campaign had its fair share of staff shake-ups before the election and that continued into his administration.

Now more than a year into the Trump administration, over a dozen notable members of both the White House and the administration at large have left their posts.

Here are the departures of White House staffers and other administration officials, starting with the most recent:

David Shulkin

Role: Secretary of Veterans Affairs

Officially started: Feb. 14, 2017

Left: March 28, 2018

408 days in his tenure

A lone holdover from the Obama administration, Shulkin has butted heads with Trump over issues of veterans' care, but it was an internal investigation alleging ethics violations and a misuse of taxpayer dollars that helped seal Shulkin's fate.

Trump announced Shulkin's departure via tweet, after declaring that Adm. Ronny L. Jackson, who has been serving as the president's physician, will be replacing him to head the agency.

The day after reports of his departure, Shulkin penned an op-ed in The New York Times criticizing the “toxic, chaotic, disrespectful and subversive” environment in Washington that he says prevented him from accomplishing work veterans need and deserve.

He wrote that his character had been attacked by politically motivated people “who wanted me out of the way.”

H.R. McMaster

Role: National Security Adviser

Officially started: Feb. 20, 2017

Left: His resignation was announced on March 22, 2018, and will become effective on April 9, 2018

413 days in his tenure

The White House confirmed that Gen. H.R. McMaster’s departure from the administration was mutually agreed upon.

McMaster's departure in early 2018 had been planned and expected, especially as Trump re-tools his team ahead of historic talks with North Korea, sources with direct knowledge told ABC News.

He was seen as adding a steady and intellectual voice to Trump’s security team, but the president chafed at his style and disposition in Oval Office briefings, the sources said. He also clashed with former Trump adviser Steve Bannon and other top military brass, including Defense Secretary Jim Mattis.

He is being replaced by John Bolton, who served as one of former President George Bush's ambassadors to the United Nations.

Rex Tillerson

Role: secretary of state

Officially started: Feb. 1, 2017

Left: March 13, 2018 (though remaining during the transition, the White House said)

406 days in his tenure

Rex Tillerson became the second agency secretary to leave Trump's Cabinet after the president announced he was being replaced by CIA Director Mike Pompeo.

Tillerson and Trump have had tumultuous points in their relationship in the past. One public dispute came in October amid reports that Tillerson called the president a "moron."

"We got along quite well but we disagreed on things," Trump told reporters shortly after tweeting his decision to replace Tillerson with CIA Director Mike Pompeo, noting how he and Tillerson "felt a bit differently" on the Iran nuclear weapons deal.

John McEntee

Role: personal aide

Officially started: Jan. 20, 2017

Left: March 12, 2018

417 days in his tenure

John McEntee was escorted out of the White House March 12, 2018, sources told ABC News. There were issues with his background clearance, according to the sources.

The review of White House staffers security clearance was ordered by the White House Chief of Staff John Kelly after staff secretary Rob Porter's departure. That list, a source told ABC News, followed standard procedures that included such options as considering whether the individual should be relieved of duty or reassigned to another administration post.

McEntee is the latest original Trump campaign aide to depart the White House.

Gary Cohn

Role: Director of the National Economic Council and the chief economic adviser to the president

Officially started: Jan. 20, 2017

Left: His resignation was announced on March 6, 2018, and his last day was on March 8, 2018

411 days in his tenure

Cohn announced his resignation amid reported ongoing debate inside the White House about the taxes Trump proposed on aluminum and steel imports. Cohn was believed to be against the tariffs.

Trump issued a statement confirming the departure, calling Cohn “a rare talent” who “did a superb job in driving our agenda, helping to deliver historic tax cuts and reforms and unleashing the American economy once again.”

Cohn did not explicitly say why he was leaving, saying in a statement that it was “an honor to serve my country” and thanking Trump “for giving me this opportunity.”

Hope Hicks

Role: Her most senior title was communications director

Officially started: Jan. 20, 2017

Left: Her resignation was announced on Feb. 28, 2018, and her last day was March 29, 2018

405 days in her tenure

Hicks was Trump's longest-serving aide when she announced that she will resign her post in the coming weeks.

Her announcement came the day after she was interviewed by the House Intelligence Committee during which she said she had occasionally told white lies on Trump's behalf, according to a source familiar with the interview. That said, White House press secretary Sarah Sanders said that her decision to resign was not related to the interview, saying that it's "something she's been thinking about for a while."

After the news broke, Trump said he "will miss having her by my side."

"Hope is outstanding and has done great work for the last three years. She is as smart and thoughtful as they come, a truly great person," the president said in a statement provided to the media by Sanders.

Rob Porter

Role: White House staff secretary

Officially started: Jan. 20, 2017

Left: Feb. 7, 2018

384 days in his tenure

Porter resigned amid multiple allegations of domestic violence from two ex-wives. Porter has denied the accusations.

While senior White House staff were aware for months of the domestic abuse allegations by Porter’s ex-wives, they were not aware of the full extent of those allegations, senior administration officials told ABC News.

Even as news of the scandal broke, White House officials initially defended Porter, with chief of staff John Kelly calling him a “man of true integrity and honor.”

Deputy press secretary Raj Shah said Trump did not know that Porter was operating under a temporary clearance during his time at the White House and said the president was "saddened" by the news and for all the individuals involved.

Omarosa Manigault-Newman

Role: Director of communications for the Office of Public Liaison

Officially started: Jan. 20, 2017

Left: She resigned on Dec. 13, 2017, but remained a White House employee until Jan. 20, 2018.

366 days in her tenure

She was fired three times from various seasons of "The Apprentice," but former reality star and Trump confidante Manigault-Newman said that she resigned, denying reports that she was fired and had to be removed from the White House.

A White House official said in a statement on Dec. 13, 2017, that Manigault-Newman resigned “to pursue other opportunities.”

Manigault-Newman spoke about her departure on "Good Morning America" the next day, saying that she and Kelly "had a very straightforward discussion of concerns that I had, issues that I raised and, as a result, I resigned."

Manigault-Newman, 43, stayed on until Jan. 20, 2018.

She was in charge of outreach to the leaders of HBCUs (historically black colleges and universities) and also oversaw the president’s visit to the Smithsonian’s African American Museum in Washington, D.C. But Manigault's day-to-day duties could not be pinpointed and, according to Politico, she used the White House as a backdrop for her 39-person bridal party to take wedding photos.

Dina Powell

Role: Deputy national security adviser

Officially started: Jan. 20, 2017

Left: Her departure was announced on Dec. 8, 2017, but she continued to serve in the White House until Jan. 12, 2018, according to Bloomberg.

358 days in her tenure

The announcement of her departure came on Dec. 8, 2017, and her final day of work in the administration was not been publicly released.

Powell has been a key player in the administration's Middle East policy, with senior adviser Jared Kushner releasing a statement saying that she "has been a valued member of the Israeli-Palestinian peace team."

White House press secretary Sanders released a statement saying Powell has been "a key, trusted adviser" and "has always planned to serve one year before returning home to New York, where she will continue to support the president's agenda and work on Middle East policy."

The kind words didn't end there, as national security adviser H.R. McMaster also released a statement asserting that "she is one of the most talented and effective leaders with whom I have ever served."

The Associated Press reported in mid-February that Powell is going to teach seminars and study groups as a non-resident senior fellow at Harvard University. And on Feb. 27, CNBC reported that a Goldman Sachs memo said that she would be returning to the bank.

Tom Price

Role: Secretary of Health and Human Services

Officially started: Feb. 10, 2017

Left: Sept. 29, 2017

232 days in his tenure

Price resigned in the midst of a controversy over his use of private jets for government travel. The former congressman and orthopedic surgeon took as many as 26 chartered planes during his short tenure a spent an estimated $1 million of taxpayer money on both the domestic trips and military flights to Africa, Asia and Europe.

"I have spent forty years both as a doctor and public servant putting people first," wrote Price to Trump in his resignation letter. "I regret that the recent events have created a distraction from these important objectives."

The HHS Office of Inspector General launched an investigation into the matter a week prior to the resignation. He was the first Cabinet member to leave his post.

Sebastian Gorka

Role: Deputy assistant to the president

Hired: Jan. 30, 2017

Left: Aug. 25, 2017

208 days in his tenure

Gorka was a deputy adviser focused on national security and counterterrorism who had worked as a paid policy consultant for Trump's campaign.

Web magazine The Federalist obtained and posted what it says is Gorka's resignation letter. "[G]iven recent events, it is clear to me that forces that do not support the MAGA promise are -- for now -- ascendant within the White House," the Federalist quotes Gorka as saying. "As a result, the best and most effective way I can support you, Mr. President, is from outside the People’s House."

The White House, however, disputed the claim that Gorka had tendered his resignation. A White House official told ABC News, "I can confirm he no longer works at the White House."

What he's doing now: Gorka will return to Breitbart News.

Steve Bannon

Role: Chief strategist and senior counselor

Hired: Nov. 13, 2016

Role: White House communications director

Officially started: July 26, 2017

Left: July 31, 2017

6 days in his tenure

Scaramucci didn't officially start in his position until July 26, so he was on the job for only six days. When his role was announced, however, he took questions from White House reporters during a press briefing.

"Mr. Scaramucci felt it was best to give chief of staff John Kelly a clean slate and the ability to build his own team," White House press secretary Sanders said in a statement.

"The president certainly felt that Anthony's comments were inappropriate for a person in that position, and he didn't want to burden Gen. Kelly," Sanders told said at a press briefing the day Scaramucci resigned.

What he's doing now: Having sold his stake in the hedge fund SkyBridge Capital to join the White House, Scaramucci has turned to doing media appearances. His first televised interview since leaving the White House was with ABC News.

Reince Priebus

Role: White House chief of staff

Role: White House press secretary

Hired: Dec. 22, 2016

Officially started: Jan. 20, 2017

Left: July 21, 2017

183 days in his tenure

Spicer officially took on the role the day Trump was sworn in as president. But Spicer was named incoming press secretary on Dec. 22, 2016, during the presidential transition. A few hours after Anthony Scaramucci was brought on the team as communications director, Spicer resigned. Spicer told ABC News that he felt "relieved" and that "organizationally" the White House communications team needed a "fresh start." Though he's no longer the press secretary, Spicer is still assisting the communications office.

Mike Dubke

Role: White House communications director

Hired: March 6, 2017

Left: May 18, 2017

74 days in his tenure

According to Axios, Dubke left on good terms, but during his time in the White House he didn't gel with those who had been with Trump since the campaign. After he resigned, Dubke offered to stay on until the end of Trump's first foreign trip and "until a transition is concluded," then–chief of staff Priebus said. Dubke's last day was June 2, 2017.

What he's doing now: Dubke has returned to his work at the strategic communications and public affairs firm he co-founded, Black Rock Group.

James Comey

Role: FBI director

Hired: June 21, 2013

Officially started: Sept. 4, 2013

Left: May 9, 2017

1,344 days in his tenure

Comey was dismissed by Trump, who the White House originally said was acting on the counsel of Attorney General Jeff Sessions and Deputy Attorney General Rod Rosenstein, after they criticized Comey's handling of the investigation into Hillary Clinton's emails. Trump later portrayed the decision as his alone and said that he was thinking about the FBI's Russian election interference probe when he resolved to fire Comey.

What he's doing now: Comey testified before the Senate Intelligence Committee on June 8, when he detailed his interactions with Trump before his firing. In early August, Flatiron Books announced a deal to publish a book by Comey in the spring of 2018.

Mike Flynn

Role in the Trump administration: National security adviser

Hired: Nov. 18, 2016

Officially started: Jan. 20, 2017

Left: Feb. 13, 2017

25 days in his tenure

Flynn, who spent much of 2016 on the campaign trail supporting Trump at rallies and events, was rewarded with the national security adviser position shortly after the election. He lasted just over three weeks before being forced to resign after it was revealed that he misled Vice President Mike Pence about the nature of multiple meetings with Russian Ambassador to the U.S. Sergey Kislyak before Trump's inauguration.

What he's doing now: Flynn and his business ties to Turkey have been part of special counsel Robert Mueller's investigation into Russia's interference in the 2016 election and possible connections to the Trump campaign.

Sally Yates

Role: Acting attorney general

Promoted: Jan. 20, 2017

Left: Jan. 30, 2017

11 days in her tenure

After nearly three decades in a career with the Department of Justice, Yates took the reins of the department with the resignation of Barack Obama's Attorney General Loretta Lynch. Yates was fired for instructing DOJ lawyers not to defend Trump's Jan. 27 executive order barring immigration from seven predominantly Muslim countries.

"For as long as I am the acting attorney general, the Department of Justice will not present arguments in defense of the executive order, unless and until I become convinced that it is appropriate to do so," Yates wrote in a letter to DOJ lawyers. She was fired hours after sending the letter. In a statement, the White House said Yates "betrayed the Department of Justice."

What she's doing now: Since she left the Department of Justice, Yates has penned two op-eds in The Washington Post and The New York Times that are critical of Trump and Attorney General Jeff Sessions.
