Donald Trump is yet to announce who his closest aides in the White House will be.
Earlier this year, the only clue he would give was: "I'm going to find the smartest and most successful people to do those jobs - they will be winners, that I can tell you."
As Vice President, .....
Mike Pence, with his extensive experience in Washington, is expected to fill a vital rolein guiding the businessman - who has no political experience - through the presidency.
But other members of the President-elect's campaign team could join him in the West Wing, including:
:: Steve Bannon, executive chairman of Mr Trump's presidential campaign
Mr Bannon was hired in August, taking a leave of absence from his other job as chief executive of the conservative Breitbart News website.
His hiring was described by the New York Times as "formally complet(ing) a merger between the most strident elements of the conservative news media and Mr Trump's campaign"
Previously an investment banker, conservative filmmaker and naval officer, he reportedly enforced pro-Trump coverage at Breitbart, having final approval on all stories written about the billionaire.
:: Kellyanne Conway, campaign manager
Ms Conway had been an adviser on the campaign but was promoted at the same time Mr Bannon was hired.
A former lawyer, she owns a polling company and has worked with a number of other Republican politicians, including Newt Gingrich, Ted Cruz and Mike Pence.
The day after Mr Trump made Ms Conway his campaign manager, he publicly expressed "regret" if his past remarks had hurt anyone, an apparent turnaround that insiders said was due to her influence.
Mr Trump has praised her as "a data and messaging expert and terrific on TV".
:: Michael Glassner, deputy campaign manager
Mr Glassner was an aide to Alaska Governor Sarah Palin, former Senator Bob Dole and an adviser on George W Bush's 2000 presidential campaign.
The consultant was hired by Mr Trump in July 2015 as national political director and played a major role in Mr Trump's idea to ban Muslims from coming to the US.
He told the Washington Post in June that he had worked at the World Trade Center and his perspective was "very much formed by 9/11".
He added: "Why wouldn't you start by trying to identify this demographic coming into the United States and see what they're doing?"
:: John Mashburn, policy director
After graduating from law school, Mr Mashburn worked with several Republican Senators and joined the Trump campaign in May.
He is described by a number of sources as a dedicated pro-lifer, although he joined the campaign a few months after Mr Trump said that, if abortions were illegal in the US, women should be given "some form of punishment" for having them.
Mr Mashburn has also spoken against public funding for what he deems to be "blasphemous" art.
:: Walid Phares, foreign policy adviser
Originally from Beirut, he moved to the US in 1990 where he teaches, writes and works for Fox News as their Middle East and terrorism expert.
He joined Mr Trump's team in March with previous political experience as national security adviser for Mitt Romney's 2012 presidential campaign.
He had criticised parts of Mr Trump's foreign policy but said he took his place on the team "because I think there needs to be a major change in our policy".
