Politics: Powerful White House staffer Rob Porter resigns — here are all the casualties of the Trump administration so far

From Steve Bannon and Tom Price to Anthony Scaramucci and Reince Priebus, here's everyone who has left the Trump administration.

Powerful White House staffer Rob Porter resigned Wednesday after both of his ex-wives accused him of physically and emotionally abusing them during their marriages.

The administration has been rocked by a series of high-profile exits — including Sean Spicer as press secretary and James Comey as FBI director — since President Donald Trump took office in January 2017.

Here are the top-level people who've either been fired or resigned from the administration, and why they left:

Rob Porter

Rob Porter, a powerful White House staffer whose profile has increased in recent months, resigned February 7 after two of his ex-wives accused him of physical and emotional abuse.

Porter denied the allegations in a statement, and said he will "ensure a smooth transition" when he leaves the White House.

The White House did not give a specific date for Porter's departure.

Here's his full statement:

"These outrageous allegations are simply false. I took the photos given to the media nearly 15 years ago and the reality behind them is nowhere close to what is being described. I have been transparent and truthful about these vile claims, but I will not further engage publicly with a coordinated smear campaign. My commitment to public service speaks for itself. I have always put duty to country first and treated others with respect. I am deeply grateful for the opportunity to have served in the Trump Administration and will seek to ensure a smooth transition when I leave the White House."

Brenda Fitzgerald

Dr. Brenda Fitzgerald resigned on January 31 after Politico reported that Fitzgerald purchased stock in Japan Tobacco while serving as CDC director.

Fitzgerald had also bought shares of the pharmaceutical companies Merck and Bayer and of the health insurer Humana.

The purchase of the tobacco shares especially raised concerns, because one of the CDC's goals is to prevent and reduce smoking.

Andrew McCabe

FBI deputy director Andrew McCabe was forced to step down on January 30, after FBI Director Christopher Wray raised concerns about an upcoming Justice Department inspector general report examining McCabe's and other senior officials' actions during the 2016 presidential campaign.

Trump had been increasingly vocal about his criticism of McCabe before his ouster.

McCabe served as the acting FBI director for a period of time in 2017 after Trump fired James Comey from the position. He began his career at the FBI in 1996.

Omarosa Manigault

Omarosa Manigault, the director of communications for the White House's Office of Public Liaison, had her official last day on January 20.

White House Press Secretary Sarah Huckabee Sanders announced December 13 that Manigault was leaving to "pursue other opportunities."

Trump fired Manigault twice on her two seasons appearing on his television show, "The Apprentice."

Tom Price

The secretary of health and human services had elicited bipartisan condemnation over the cost of his air travel.

Tom Price had cost taxpayers more than $1 million between his use of private planes for domestic travel and military jets for recent trips to Africa, Europe, and Asia, Politico reported.

He resigned September 29.

Sebastian Gorka

A White House official confirmed Gorka's departure from the Trump administration on August 25.

The former Breitbart News staffer and ally of chief strategist Steve Bannon served as a deputy assistant to President Donald Trump.

In his departing letter, first published on a pro-Trump website, Gorka told Trump he could better serve the president's "America First" agenda from the outside.

Gorka was aligned with a once prominent nationalist arm of the Trump administration, occupied most prominently by Bannon and Stephen Miller, a senior policy adviser.

Bannon's departure a week earlier was seen as a significant blow to other nationalist, far-right figures in the White House, and Gorka implied as much in his letter, saying it was clear to him that "forces that do not support the MAGA promise are — for now — ascendant within the White House."

Steve Bannon

White House officials confirmed that Trump had dismissed Bannon, his chief strategist, on August 18 after reports of clashes between Bannon and other members of the White House reached a fever pitch in recent days.

Bannon, who was instrumental in focusing the message of Trump's 2016 campaign, was considered the main conduit between Trump and his base of far-right voters. Bannon submitted his resignation to Trump earlier in August, The New York Times reports.

Matt Drudge, the conservative blogger, said Bannon might return to his former job as executive chairman of Breitbart News.

Anthony Scaramucci

Scaramucci was hired as the White House communications director and then dismissed in less than two weeks. The decision came at the urging of John Kelly, the new White House chief of staff, according to a Times report.

Scaramucci most notably made headlines for his interview with The New Yorker in which he unleashed an expletive-filled tirade against members of the Trump administration.

Reince Priebus

Priebus resigned as White House chief of staff six months into his tenure after a public feud with Scaramucci.

Trump announced in a tweet on June 28 that Kelly, the secretary of homeland security at the time, would take over for Priebus. Priebus resigned less than a week after Sean Spicer, the former press secretary, who was considered a Priebus ally in the White House.

Sean Spicer

Spicer, the embattled White House press secretary, resigned on July 21 after telling Trump he vehemently disagreed with the selection of Scaramucci as White House communications director.

Spicer's tenure was marred by controversy and a sometimes awkward relationship with the president. Spicer said at the time that he would stay in his role until August.

Michael Dubke

Dubke resigned as the White House communications director in May. Dubke was replaced by Scaramucci, the founder of a hedge fund and a top Trump donor.

Walter Shaub

Shaub resigned as the director of the Office of Government Ethics in July after clashing with the White House over Trump's complicated financial holdings.

Shaub called the Trump administration a "laughingstock" after his resignation, and he advocated strengthening the US's ethical and financial disclosure rules, according to The Times.

James Comey

Trump fired Comey as FBI director in May.

At the time of his firing, Comey was handling the bureau's investigation into whether the Trump campaign colluded with Russia to meddle in the 2016 election, creating a firestorm of controversy for the Trump administration.

Comey was the second FBI director to be fired by a president — Bill Clinton fired William Sessions in 1993.

Michael Flynn

Flynn resigned in February after serving as national security adviser for less than a month.

Flynn had misled Vice President Mike Pence and other administration officials about what he and Sergey Kislyak, Russia's ambassador to the US, talked about in phone conversations during the transition — according to reports, they had discussed the Obama administration's sanctions against Russia.

Sally Yates

Trump fired Yates, an appointee of President Barack Obama, as acting attorney general within his first 10 days in office. Yates had refused to uphold Trump's executive order on immigration and denounced it as unlawful.

Yates was also instrumental in the events that led to Flynn's ouster, as she had informed Trump days after his inauguration that Flynn could be vulnerable to Russian blackmail.

Preet Bharara

Trump fired Bharara as the US attorney for the Southern District of Manhattan in March after he refused to submit his resignation to Attorney General Jeff Sessions.

Bharara was fired along with several other Obama-era US attorneys, though Trump had initially asked Bharara during the transition to remain in his position.

Katie Walsh

Walsh, the former deputy chief of staff and close ally of Priebus, left the White House after nine weeks to run America First Policies, a pro-Trump group outside the government.
