US Health and Human Services Secretary Tom Price resigned under pressure from President Donald Trump on Friday in an uproar over Price’s use of costly private charter planes for government business.

The following is a partial list of officials who have been fired or have left the administration since Trump took office on January 20, as well as people who were nominated by Trump for a position, but did not take the job:

* Stephen Bannon — Trump’s chief strategist, who had been a driving force behind the president’s anti-globalisation and pro-nationalist agenda that helped propel him to election victory, was fired by Trump in mid-August. He had repeatedly clashed with more moderate factions in the White House.

* Philip Bilden — a private equity executive and former military intelligence officer picked by Trump for secretary of the Navy, withdrew from consideration in February because of government conflict-of-interest rules.

* James Comey — the Federal Bureau of Investigation director leading a probe into possible collusion between the Trump 2016 presidential campaign and Russia to influence the election outcome, was fired by Trump in May.

* James Donovan — a Goldman Sachs Group Inc banker who was nominated by Trump as deputy Treasury secretary, withdrew his name in May.

* Michael Dubke — founder of Crossroads Media, resigned as White House communications director in May.

* Michael Flynn — resigned in February as Trump’s national security adviser after disclosures that he had discussed US sanctions on Russia with the Russian ambassador to the United States before Trump took office and misled Vice President Mike Pence about the conversations.

* Mark Green — Trump’s nominee for Army secretary, who had served in the 160th Special Operations Aviation Regiment, withdrew his name from consideration in May.

* Gerrit Lansing — White House chief digital officer, stepped down in February after failing to pass an FBI background check, according to Politico.

* Jason Miller — communications director for Trump’s transition team who was named by the president-elect in December as White House communications director, said days later that he would not take the job.

* Reince Priebus — the former chairman of the Republican National Committee was replaced by John Kelly as Trump’s chief of staff in July. A confidant of the president said Trump had lost confidence in Priebus after major legislative items failed to pass the US Congress.

* Todd Ricketts — a co-owner of the Chicago Cubs baseball team and Trump’s choice for deputy secretary of commerce, withdrew from consideration in April.

* Anthony Scaramucci — the White House communications director was fired by Trump in July after just 10 days on the job after profanity-laced comments to The New Yorker magazine were published.

* Walter Shaub — the head of the US Office of Government Ethics, who clashed with Trump and his administration, stepped down in July before his five-year term was to end.

* Michael Short — senior White House assistant press secretary, resigned in July.

* Sean Spicer — resigned as White House press secretary in July, ending a turbulent tenure after Trump named Scaramucci as White House communications director.

* Robin Townley — an aide to national security adviser Flynn, was rejected in February after he was denied security clearance to serve on the US National Security Council, according to Politico.

* Vincent Viola — an Army veteran and a former chairman of the New York Mercantile Exchange, nominated by Trump to be secretary of the Army, withdrew his name from consideration in February.

* Katie Walsh — deputy White House chief of staff, was transferred to the outside pro-Trump group America First Policies in March, according to Politico.

* Caroline Wiles — Trump’s director of scheduling, resigned in February after failing a background check, according to Politico.

* Sally Yates — acting US attorney general, was fired by Trump in January after she ordered Justice Department lawyers not to enforce Trump’s immigration ban.
