In less than two weeks, at least three Trump administration officials have either tender their resignation letter or left the White House. 

This followed the exit of Secretary of State Rex Tillerson who was fired on March 13. 

Tillerson's sack comes just weeks after White House Communications Director Hope Hicks and Staff Secretary Rob Porter resigned.

Bounce News takes a look at some of the top Trump administration departures.

1) Lt General HR McMaster

National Security Adviser

A White House source said Trump and McMaster "mutually agreed" on the decision for the national security adviser to resign.

The source denied that the reshuffle was related to recent developments in Trump's cabinet, saying it was the result of "ongoing conversations" between the two officials. 

In confirming his resignation, McMaster also announced his retirement from the US Army. 

2) Andrew McCabe 

Deputy FBI Director 

After his firing in March as the FBI deputy director, Andrew McCabe said he had been targeted because he is a crucial witness into whether President Donald Trump tried to obstruct the Russia investigation. 

According to the Justice Department, McCabe had leaked information to reporters and misled investigators about his actions - allegations he denied. 

McCabe corroborated former FBI Director James Comey's claims that Trump tried to pressure him into ending the Russia probe. 

3) Rex Tillerson - Fired

Secretary of State

Tillerson, a former top executive of the energy giant Exxon, took office on February 1, 2017.

His relationship with Trump quickly turned rocky over the Iran nuclear agreement, the Gulf crisis and North Korea's nuclear weapons. 

But things took a serious turn for the worse in October after news reports broke that Tillerson described the US president as a "f$@&ing moron".

Tillerson denied he had insulted his boss, but their relationship apparently couldn't recover.

4) Steve Bannon - Resigned

Chief Strategist 

Bannon co-founded Breitbart News, a website with the purported goal of countering mainstream media and providing a platform for movements at the right-end of the political spectrum.

The 64-year-old's relationship with the president soured following speculation he was leaking compromising information to the press, and complaining about not receiving enough credit for his policy contributions.

He presented his resignation on August 4, 2017.

5) Michael Flynn - Resigned

National Security Adviser 

Flynn, a former army general, joined Trump early on the campaign trail and assumed the national security adviser role in January 2017 - only to resign less than a month later amid an ongoing investigation into alleged Russian meddling in the 2016 elections.

He has since pleaded guilty to lying to the FBI in that investigation.

6) James Comey - Fired

FBI Director 

Former FBI director James Comey was fired by Trump in May 2017.

Comey was leading an ongoing investigation into alleged Russian interference in the 2016 presidential election.

His dismissal raised fears the president was looking to disrupt the integrity of the inquiry.

It is certain the last has not been heard of the sacks and resignations, the question is "Who is next?"
