You're Fired: The Many Trump Campaign Aides Who've Heard Those Famous Words

Paul Manafort is the latest to leave.

— -- Paul Manafort has become the latest senior Donald Trump campaign adviser who must now add the word “former” to his campaign title.

Manafort stepped down as campaign chair just two days after Trump hired Kellyanne Conway to be his new campaign manager and Steve Bannon to serve in the position of campaign chief executive.

In a statement, Trump thanked Manafort for his service to the campaign.

"I am very appreciative for his great work in helping to get us where we are today, and in particular his work guiding us through the delegate and convention process," according to the statement.

While campaign shake-ups are not unusual, the Trump campaign has seen an unusually high number of departures for a candidate who didn’t have many campaign staffers to begin with.

Here’s a look at some of the other senior staffers who have parted ways with the campaign:

Corey Lewandowski

The firing of campaign manager Corey Lewandowski was the most high-profile firing of the campaign.

His exit came amidst reported infighting between Lewandowski and new campaign chairman Paul Manafort, with sources telling ABC News at the time that the final push came to remove Lewandowski came from Trump's three eldest children, his son-in-law Jared Kushner, Manafort and other longtime aides.

Lewandowski is now a paid commentator at CNN.

Ed Brookover

Brookover, who served as a liaison between the Trump campaign and the Republican National Committee, and who also served as Trump's delegate manager, was fired from the campaign in early August.

“The campaign has parted ways with Ed, but we are thankful to him for his many contributions and appreciate his continued support,” the Trump campaign said in a statement about Brookover.

Brookover worked as campaign manager for Ben Carson before joining Trump's staff.

Rick Wiley

Rick Wiley, who served as the campaign manager to Scott Walker’s short-lived 2016 campaign, was hired as the Trump campaign’s national political director in April. But his time at the Trump campaign would also prove to be short-lived, parting ways with the campaign in late May, just weeks after he was hired.

The campaign sought to cast Wiley’s short tenure as a temporary role, saying in a statement that he was “hired on a short-term basis as a consultant until the campaign was running full steam” and thanked Wiley for “helping us during this transition period.”

Michael Caputo

Caputo was an adviser and a high-ranking communications staffer at the Trump campaign before he tweeted “Ding dong the witch is dead” after Lewandowski’s firing. After the controversial tweet, Caputo resigned from the campaign.

Kevin Kellems

Kellems, a former George W. Bush administration staffer, was brought into the campaign with the task of building out the campaign’s surrogate operations in late June.

But after less than two weeks on the job, Kellems resigned.

Roger Stone

Gone but not forgotten, Roger Stone ceased to be a senior adviser to the Trump campaign last August.

Though Stone may no longer be on Trump’s payroll, he continues to be a confidante of Trump’s in an unofficial capacity.

Sam Nunberg

Sam Nunberg became Trump's first full-time paid political adviser back in 2014. But he was also one of the first to hear the famous words "You're fired." Nunberg was booted by Trump last August after racially charged Facebook posts from years earlier were made public.

Nunberg has since been sued by Trump for $10 million on allegations that he leaked confidential campaign information to the press in violation of a confidentiality agreement — a charge Nunberg denies.

Barry Bennett

Another senior adviser who has since parted ways with Trump is Barry Bennett.
