A few years ago, Donald Trump was mainly famous for shouting "you're fired".

And since become president, his firing trigger finger is still as itchy.

His casualties have included both his own hires and some leftovers from the Obama administration.

Some of the firings have been more controversial than others, but the recent White House shakeup has just highlighted the number of figures that have come and gone over the past eight months.

Sally Yates

Yates, in her role as the acting attorney general, was the first notable firing.

After just 10 days in the role, she defied Trump by ordering the Justice Department to not enforce his new travel ban.

At the time, then press secretary Sean Spicer said that Yates had "betrayed the Department of Justice by refusing to enforce a legal order designed to protect the citizens of the United States".

Michael Flynn

Flynn lasted just 23 days in his role as Trump's national security adviser after it was revealed that he had contacts with Russia.

It had emerged that he had discussed lifting US sanctions on Russia with their ambassador in Washington.

He misled Vice President Mike Pence about these meetings, and eventually resigned.

James Comey

Arguably the most controversial firing, and one that sent shockwaves around Washington.

Unlike Flynn, Comey was hired in the Obama era, but presidents don't often fire their FBI directors.

However, Trump is unlike most presidents. As the Russia investigations grew, Trump became restless. After Comey refused to pledge his loyalty, the axe was brought down.

Trump claims it was because of his handling of the Hillary Clinton email scandal, but under oath, Comey suggested he was fired to "change the way the Russia investigation was being conducted."

Sean Spicer

The embattled former press secretary got off to a rough start when back in January he got into a row over the size of Trump's inauguration crowd.

Spicer kept on fighting with the press, Trump at one stage said that he was "doing a good job but he gets beat up".

Eventually, the hiring of Anthony Scaramucci brought about his resignation, ending months of speculation about his future.

Reince Priebus

In 2012, Trump criticised Obama for having three chiefs of staff in as many years. But Trump is now on his second in six months.

Priebus's time as chief of staff was one of the shortest ever. And once Scaramucci was in the White House, he soon began gunning for Priebus.

He called Priebus "a f****** paranoid schizophrenic" and accused him of leaking to the press.

Anthony Scaramucci

"The Mooch", as he is known by his friends and colleagues, was brought into the White House to bring a new period of calm to the White House.

Ten days after he joined the West Wing as communications director, he was let go by Trump.

His departure came days after his "schizophrenic" rant about Priebus and on the same day that General John Kelly was sworn in as the new chief of staff.

Steve Bannon

Much like in the final days of Sean Spicer, the rumour mill went into overdrive over a possible Bannon firing.

The controversial former Breitbart editor came under the spotlight in the wake of the Charlottesville attack, when a neo-Nazi mowed down anti-fascist protesters, killing a woman.

Once seen as the most important figure in the White House other than Trump himself, he quickly fell out of favour with the president and was eventually cast aside.

The list goes on...

Those mentioned above are simply the big names to have been let go. Others who have also walked out of the door or been pushed include Deputy White House Chief of Staff Kate Walsh; Director of Communications Mike Dubke; Assistant Press Secretary Michael Short; and government ethics adviser Walter Schaub.

But question marks remain over several people include Attorney General Jeff Sessions, who has been attacked regularly by Trump in recent weeks.

However, the biggest target is on the back of special counsel Robert Mueller, who leads the Russian investigation.

He recently started looked into Trump's business interests, which angered the president. However Republicans have warned that if Mueller is removed, it will cause a whole new storm over Washington.
