Joe Biden has formally nominated the members of his cabinet, as he prepares to take office in the White House on 20 January.
Mr Biden’s team vetted potential candidates for cabinet positions after he was announced as the winner of 3 November’s election, despite Donald Trump repeatedly refusing to concede and initially blocking the transition process.
Mr Trump seemed to soften his stance in late November, as he accepted that a formal transition for Mr Biden to take office should begin, though still has not accepted defeat.
After the General Services Administration acknowledged Mr Biden as the “apparent winner” of the presidential election in late November, Mr Trump said that the agency must “do what needs to be done with regard to initial protocols”.

Vice-president elect Kamala Harris, Mr Biden’s chief of staff Ron Klain and his deputy chief of staff Jen O’Malley Dillon were previously announced as part of the president-elect’s team, before he revealed more nominations in late November and December. He filled out the final positions in January.
A number of Mr Biden’s first picks for his national security and foreign policy teams have worked with him before, while the hires are more diverse than any previous US cabinet.
Here are Mr Biden’s picks for his cabinet.

Antony Blinken, secretary of state
Antony Blinken was announced as Mr Biden’s pick for secretary of state on Monday 23 November, to replace Mike Pompeo in Mr Trump’s administration.
Mr Blinken was born in New York City. He went on to study at Harvard University and earned a law degree from Columbia Law School.
Between 1994 and 2001 he served on the National Security Council at the White House and then worked as staff director for the Senate Foreign Relations Committee. He joined Mr Biden’s unsuccessful 2008 presidential campaign, before he was selected by Barack Obama as his running mate.
The longtime diplomat was part of the Obama transition team in 2008. He worked directly with Mr Biden when he was vice president, serving as national security adviser from 2009 to 2013.
Mr Blinken then served as deputy secretary of state from 2015 to 2017 during president Obama’s second term.
He reunited with Mr Biden to work as a foreign policy adviser for his 2020 campaign and has publicly spoken about the president-elect’s plans in regards to foreign policy.
In October, he said that the Biden administration will “undertake a strategic review” of America’s relationship with Saudi Arabia, and confirmed that it will “will continue non-nuclear” sanctions against Iran.
He previously called Brexit a “total mess” and compared the decision to the far-right French politician Marine Le Pen.
However, Mr Blinken has praised the Trump administration’s normalisation agreement between Bahrain, the United Arab Emirates and Israel.
In an interview with the Washington Post, Mr Obama described Mr Blinken as “outstanding. Smart, gracious, a skilled diplomat, well-regarded around the world”.
John Kerry, special presidential envoy for climate
John Kerry was announced as Mr Biden’s special presidential envoy for climate on 23 November, becoming only the second person appointed to the role.

While in the role, he played an important part in the creation of the Paris climate agreement, which commits countries to reducing greenhouse gas emissions.
Mr Trump then withdrew the US from the agreement but Mr Biden has promised to immediately rejoin it.
Mr Kerry was part of the climate taskforce during Mr Biden’s presidential campaign. The president-elect’s transition team said that his appointment shows that Mr Biden sees climate change as an “urgent national security issue”.
Mr Kerry tweeted: “America will soon have a government that treats the climate crisis as the urgent national security threat it is.”
He does not need to be confirmed by the Senate for his role.

After working as chief counsel to Minnesota senator Amy Klobuchar, he served as an adviser for Hillary Clinton during the 2008 Democratic primaries, and then to Mr Obama for the 2008 presidential election.
After Ms Clinton was made secretary of state during Mr Obama’s presidency, Mr Sullivan worked as her deputy chief of staff and director of policy planning until she stepped down in 2013.
He then taught at Yale Law School and joined the London and New York–based firm, Macro Advisory Partners.
A statement from Mr Biden’s transition team read: “During his time in government, Sullivan was a lead negotiator in the initial talks that paved the way for the Iran nuclear deal and played a key role in the US-brokered negotiations that led to a ceasefire in Gaza in 2012.
“He also played a key role in shaping the Asia-Pacific rebalance strategy at both the State Department and the White House.”
Mr Sullivan also tweeted that president-elect Biden “taught me what it takes to safeguard our national security at the highest levels of our government. Now, he has asked me to serve as his national security advisor”.
