Meet President Donald Trump's inner circle and cabinet.
Vice-President Mike Pence
The former Indiana governor is a favourite among social conservatives and boasts considerable experience in Washington.
Mr Pence was raised Roman Catholic along with his five siblings in Columbus, Indiana, and says he was inspired by liberal icons John F Kennedy and Martin Luther King Jr.
He is known for his staunch opposition to abortion, signing a bill to ban abortion in Indiana on the basis of disability, gender or race of the foetus.
He has said he would favour overturning a 1973 Supreme Court judgement, often referred to as the Roe v Wade case, which bars the US government from prohibiting abortions.
Women's rights advocates have mounted online campaigns against his views, including asking people to call his office to tell them about their periods or to make donations to family-planning organisations in Mr Pence's name.
He served as the chair of the House Republican Conference, the third highest-ranking Republican leadership position.
He also chaired the Republican Study Group, a coalition of conservative House Republicans, which could give him a boost with some evangelicals of the party that have questioned Mr Trump's ideological purity, the BBC's Anthony Zurcher says.
John Kelly - Chief of Staff
The president initially nominated the retired Marine General to oversee Homeland Security before promoting him to chief of staff, replacing Reince Priebus.
Mr Kelly was a key influence on the decision to fire the director of communications, Anthony Scaramucci, after just 10 days in office.
The former four-star general, whose military career spans four decades, quit as head of the military's Southern Command, which oversees military activities in Latin America and the Caribbean, to join the Trump administration.
Mr Kelly is the highest-ranking military officer to lose a child in the wars in Iraq and Afghanistan.
His son Robert, a first lieutenant in the Marines, was killed in combat when he stepped on a landmine in Afghanistan in 2010.
The seasoned commander had previously clashed with the Obama administration on illegal immigration at the US-Mexican border.
In December Mr Trump said Mr Kelly would leave his post by the end of the year. It followed reports that the relationship between the two had deteriorated.
John Bolton - National Security Adviser
Known for his walrus moustache, Mr Bolton has served in the administrations of Ronald Reagan, George HW Bush and George W Bush.
The second Bush appointed him as US envoy to the UN, during which time diplomats privately criticised Mr Bolton's style as abrasive.
A strident neo-conservative, Mr Bolton helped build the case that Saddam Hussein possessed weapons of mass destruction, which turned out to be wrong.
Mr Bolton does not appear to have moderated his views since his last spell in government. He stands by the invasion of Iraq and has called for the US to attack Iran and North Korea.
Stephen Miller - Senior policy adviser
Mr Miller was a top aide to Jeff Sessions before he joined the Trump campaign.
He often warmed up crowds before Mr Trump took the stage at rallies on the campaign trail and was subsequently named the national policy director for Mr Trump's transition team. He also served as the campaign's chief speechwriter.
As a senior adviser, Mr Miller manages White House policy staff, speechwriting functions and ensures the implementation of the president-elect's policy.
"He is deeply committed to the America First agenda, and understands the policies and actions necessary to put that agenda into effect," Mr Trump said.
A combative interview with CNN's Jake Tapper ended prematurely when the CNN host lost patience.
Kellyanne Conway - Counsellor to the President
The Republican strategist and veteran pollster serves as the highest-ranking woman in the White House after having earlier been considered for the role of press secretary.
"She is a tireless and tenacious advocate of my agenda and has amazing insights on how to effectively communicate our message," Mr Trump said.
The mother of four was promoted as Mr Trump's third campaign manager in August 2016 as part of another staff shake-up after the Republican convention.
She has been praised as the "Trump whisperer" and became the first woman to run a successful US presidential campaign.
Michael Cohen - former personal lawyer
Mr Cohen was more than a lawyer, he was a self-professed fixer. And his loyalty was unflinching - he once said he would take a bullet for Mr Trump.
The two were introduced by Donald Trump Jr in 2006 and Mr Cohen soon became part of the family.
But that close personal and professional relationship began disintegrating the moment Stormy Daniels became news.
Ever since the porn actress claimed she had an affair with Mr Trump - and that Mr Cohen paid her off - their friendship has been under strain.
After his offices were raided by the FBI, he said his family was his top priority. In return, Mr Trump and his aides have been disparaging of Mr Cohen.
This soured further when audio was released by Mr Cohen's lawyer of a conversation in 2016 of candidate Trump and Mr Cohen discussing the payment.
Now the news that Mr Cohen had struck a deal with the FBI - as they investigate possible fraud and campaign finance violations - could put even greater distance between them.
A former model born in Slovenia, Melania married Donald Trump in January 2005.
She has stood by her husband despite reports of his infidelities, alleged sexual assaults, and campaign revelations that he boasted about groping women.
In July 2016 she made headlines after making a speech at the Republican National Convention, which she was accused of having plagiarised from one made by Michelle Obama in 2008.
In an October interview with CNN, she was asked what she would change about her husband. She replied: "His tweeting".
She stayed in New York with their son Barron until he finished his school term, before formally moving into the White House in June 2017.
Perhaps the best-known of Donald Trump's children, the only daughter of his marriage to Ivana, his first wife.
A model in her early years, she was a vice-president at The Trump Organization, before stepping down when her father became president. She also launched her eponymous fashion line and was also a judge on her father's reality TV show The Apprentice.
Her brother Donald Junior says Ivanka is the favourite child and is referred to as "Daddy's little girl".
She was given a level of authority in the family business that none of his wives ever had and is said to have handled some of the company's biggest deals.
Since Mr Trump became president, she has regularly been seen at his side. She, rather than the first lady, travelled with him to an air base in early February 2017 to mark the return of the body of a soldier killed in a raid in Yemen.
She joined her father's administration as an unpaid aide with the title Adviser to the President, and has her own office in the West Wing of the White House.
After her father became president, Ivanka said she had resigned from her signature apparel and accessories brand.
She converted to Judaism after marrying Jared Kushner in 2009.
Mr Trump's media-shy son-in-law is the son of a prominent New York property developer and is married to Ivanka Trump.
Mr Kushner arrived at the White House with the broadest of briefs and has come out on top of several rounds of infighting in the West Wing.
But he increasingly faces a battle for relevance - stripped of his top-level security clearance and locked in a power struggle.
It emerged that Mr Kushner had attempted to arrange a communications backchannel with Russia during the presidential transition. But Mr Kushner denies any suggestion of collusion with the Kremlin.
He is a wealthy property developer and publisher. He owns 666 Fifth Avenue, a skyscraper a few blocks down from Trump Tower, and in 2006, aged just 25, he bought the once-venerable New York Observer newspaper.
Mr Kushner was born and raised in comfort in Livingston, New Jersey, alongside two sisters and a brother. His grandparents escaped Poland during the war, arriving in the US in 1949, and his father Charles made his fortune as a New Jersey property mogul.
Donald Trump Jr
Donald Trump's eldest son from his first marriage to Ivana is now executive vice-president of The Trump Organization, but had played a significant role during Mr Trump's campaign.
In July 2017, it emerged that Mr Trump Jr - along with Jared Kushner and former campaign manager Paul Manafort - had met with a Russian lawyer with links to the Kremlin during Mr Trump's presidential campaign.
He initially explained that the meeting was held to discuss Russian adoptions, which were suspended after the US announced sanctions on Russia in 2012.
But emails showed that he decided to attend the meeting after being offered damaging information about Hillary Clinton.
He and President Trump have since described the meeting as "opposition research" that any politician would engage in.
The third child of Mr Trump's marriage to Ivana, he is also an executive vice-president of the Trump Organization.
He is president of the Trump Winery in Virginia and oversees Trump golf clubs.
In 2006, he also set up the Eric Trump Foundation, which was embroiled in a controversy over donations.
Mike Pompeo - Secretary of State-designate
The former hardline Republican Congressman became US spymaster as head of the CIA. Now he has been nominated to take over as America's top diplomat following Mr Trump's abrupt firing of Rex Tillerson.
The three-term Tea Party Republican from Wichita, Kansas, was a vehement critic of the Obama administration's nuclear deal with Iran and has defended the National Security Agency's bulk data collection programme.
He also opposes closing Guantanamo Bay and, after visiting the prison in 2013, he remarked that some inmates who had declared a hunger strike looked like they had put on weight.
In January, he told the BBC that Russia would target the US mid-term elections.
Steven Mnuchin - Treasury Secretary
Not all of Mr Trump's supporters welcomed the idea of handing the levers of national tax policy to a consummate Wall Street insider.
During his time running the OneWest bank, his business oversaw thousands of home foreclosures in the aftermath of the subprime mortgage crisis.
Mr Mnuchin amassed a fortune during his 17 years at Goldman Sachs before founding the movie production company behind such box office hits as the X-Men franchise and American Sniper.
The treasury secretary found himself under investigation after he took a government-subsidised trip to Fort Knox with his Scottish wife Louis Linton, amid claims they were sightseeing.
James Mattis - Secretary of Defense
Gen Mattis served in the Marine Corps for 44 years, fighting in Iraq and Afghanistan. A counterinsurgency expert, he played a key role in fighting in Falluja in 2004.
From 2010-13 he led US Central Command, which covers an area from the Horn of Africa into Central Asia and includes all US military operations in Iraq and Afghanistan.
He is known for his blunt comments. In 2005 he was criticised after saying - in reference to Afghan men who "slap women around... because they didn't wear a veil" - that "it's a hell of a lot of fun to shoot them".
But he is also described as a popular leader, well-liked by those he commanded, and an avid reader of literature on warfare. His nicknames were warrior monk and mad dog.
As Gen Mattis retired in 2013, the law that bans military officers from serving as defence chief for seven years after leaving active duty was waived.
Elaine Chao - Transportation Secretary
Born in Taiwan, she became the first Asian-American woman to hold a position in a presidential cabinet when she led the Labor Department under President Bush from 2001-09.
Ms Chao, who is married to Senate Majority Leader Mitch McConnell, served as deputy secretary of transportation and director of the Peace Corps in former President George HW Bush's administration.
She came to the US with her family at the age of eight and settled in New York, where her father became a shipping magnate.
Jeff Sessions - Attorney General
Mr Sessions had been one of Mr Trump's closest allies throughout the campaign, and his loyalty was rewarded when he became the nation's top prosecutor.
But the former senator from Alabama has appeared isolated after the president said he never would have appointed him if he had known that Mr Sessions would later recuse himself from the Russian investigation.
Mr Sessions later said the president's attacks were "kinda hurtful".
Allegations of racism have dogged him throughout his career, and were raised during his confirmation hearing in the Senate.
He lost out on a federal judgeship back in 1986 when former colleagues said he had used the N-word.
But during the hearing, he acknowledged "the horrendous impact that relentless and systemic discrimination and the denial of voting rights has had on our African-American brothers and sisters".
Gina Haspel - nominated as CIA director
Ms Haspel has been chosen by Mr Trump to take over from Mike Pompeo as he steps up to become secretary of state.
If confirmed, she will become the first female director of the Central Intelligence Agency.
A career intelligence officer with more than 30 years' experience, she was appointed CIA deputy director last year.
Controversially, she ran a prison in Thailand where suspected al-Qaeda members were tortured by waterboarding in 2002.
Nikki Haley - US ambassador to the UN
In the Republican primaries, Nikki Haley, then the governor of South Carolina, first backed Mr Rubio and later Texas Senator Ted Cruz before she finally threw her support behind Mr Trump.
She was highly critical of Mr Trump's proposal to ban Muslim immigrants, calling it "un-American", and also of his refusal to release tax records.
Announcing her as the first woman chosen for his cabinet, Mr Trump called her "a proven dealmaker" who will be "a great leader representing us on the world stage".
The daughter of Indian immigrants, Mrs Haley was the first minority and female governor of South Carolina, a deeply conservative state with a long history of racial tensions.
At times, she has contradicted the White House, and said "everybody knows that Russia meddled in our elections" despite the president's more nuanced stance.
Rick Perry - Energy Secretary
The former Texas governor heads an agency he proposed to eliminate during his failed 2012 presidential campaign.
The former Dancing with the Stars contestant was a vocal critic of Mr Trump, calling him a "barking carnival act" and a "cancer on conservatism" before he dropped out of his second unsuccessful bid for the White House in 2015.
As governor of Texas, Mr Perry called for lighter regulation on the oil industry and referred to the science around climate change as "unsettled".
After being picked by Mr Trump, he stepped down from the board of directors at Energy Transfer Partners, the company behind the controversial Dakota Access Pipeline in North Dakota.
Betsy DeVos - Education Secretary
A wealthy Republican Party donor and a former Michigan Republican Party chairwoman, she became the second woman nominated for a cabinet position.
She had however once described Mr Trump as "an interloper" who didn't represent the Republican Party.
Mrs DeVos is an advocate of Republican-favoured charter schools, which are publicly funded and set up by teachers, parents, or community groups outside the state school system.
She also previously supported the Common Core education standards that Mr Trump and many conservatives have pilloried.
Mr Trump called her "a brilliant and passionate education advocate" but she was criticised after appearing to struggle at times during her nomination hearing.
Alexander Acosta - Secretary of Labor
The former Florida International University law dean has worked for the National Labor Relations Board, the Justice Department's civil rights division, and the US Attorney for the Southern District of Florida.
Before joining the Trump administration, he was chairman of the US Century Bank, the largest domestically owned Hispanic community bank in Florida.
During his time serving as US Attorney in Florida, he cut a secret deal with billionaire financier Jeffrey Epstein, who had been accused of sexual misconduct with underage girls.
The deal was criticised by lawyers representing the alleged victims, saying that the punishment was too lenient.
Ryan Zinke - Secretary of the Interior
The former Navy SEAL was picked to lead the agency that oversees federal land, including national parks such as Yosemite and Yellowstone.
He is a former congressman for Montana, where he was raised near Glacier National Park.
Mr Zinke has bucked his party on the issue of privatisation or transfer of public lands to states, which he believes should remain under federal control.
Environmental advocacy groups condemned the pick, accusing him of being in hock to corporate polluters.
Mr Zinke's time in office has been overshadowed by a series of alleged ethics violations.
President Trump announced on 15 December 2018 that he would leave his post at the end of the month.
Andrew Wheeler- Environmental Protection Agency (EPA) boss
The former energy lobbyist was appointed chief of the EPA after Scott Pruitt resigned amid a string of scandals regarding his spending habits and allegations of ethical misconduct.
Mr Wheeler, who served as the No 2 official at the EPA, was confirmed as Mr Pruitt's deputy in April.
The 53-year-old Ohio native worked for nine years as lobbyist for the coal industry, representing companies that often had business before the EPA.
He worked as a special assistant for the EPA's Office of Pollution Prevention and Toxics during the 1990s before becoming an aide at the Senate's Environment Committee.
He also was a staffer for Republican Senator Jim Inhofe, who served as a chairman for the Senate environmental panel and has dismissed global warming as a hoax.
In announcing Mr Pruitt's resignation, the president tweeted he has "no doubt that Andy will continue on with our great and lasting EPA agenda. We have made tremendous progress and the future of the EPA is very bright!"
Peter Navarro - Director of Trade and Industrial Policy
Mr Navarro is a top economic advisor to the president and director of the White House's Trade and Manufacturing Policy office.
A staunch anti-China and pro-tariff economist, Mr Navarro was sidelined and demoted by Chief of Staff John Kelly and other free trade economists on the National Economic Council last autumn.
However, the former Trump campaign advisor - an economics professor at the University of California, Irvine - still wields influence in the White House, as seen by the tariffs placed on steel and aluminium.
