US President-elect Joe Biden took office on Wednesday, starting off with several measures to tackle the Covid-19 crisis, revive the battered economy and reverse many of former president Donald Trump’s controversial policies. FRANCE 24 takes a look at his cabinet nominees. The 78-year-old Democrat took office a day after the US Covid-19 death toll passed 400,000. Biden has pledged to vaccinate 100 million Americans against Covid-19 in his first 100 days in office and hopes for quick congressional approval of his $1.9 trillion economic stimulus plan.Biden has also vowed to restore US global leadership after four years of former president Donald Trump’s “America First” agenda and reverse many of his predecessor’s controversial policies on climate change and immigration. FRANCE 24 takes a look at Biden and Vice President Kamala Harris’s key cabinet picks – the majority of whom await confirmation from the US Senate.Secretary of State: Antony BlinkenA longstanding Biden aide, Blinken, 58, served as deputy secretary of state during former president Barack Obama’s second term from 2015 to 2017. Prior to that, he was deputy assistant to Obama with responsibility for foreign affairs and national security adviser to then vice president Biden from 2009 to 2013.Blinken was also staff director for the Senate Foreign Relations Committee, then headed by Biden, from 2002 to 2008, and was a member of Bill Clinton’s National Security Council from 1994 to 1998.Blinken’s father and uncle both served as US ambassadors. He spent much of his childhood in Paris and speaks fluent French.White House Chief of Staff: Ron KlainKlain, 59, has served as a key aide to Biden since the 1980s, first in the Senate, and later during the first two years of his vice presidency from 2009 to 2011. He fell out with Biden briefly in 2015 by choosing to support Hillary Clinton’s presidential bid while Biden was still hoping to win his party’s nomination.A former lawyer and veteran political insider, Klain also worked as former vice president Al Gore’s chief of staff from 1995 to 1999.Klain served as former president Barack Obama’s “Ebola Tsar” for a short period in 2014 and has been an outspoken critic of Trump’s handling of the Covid-19 pandemic.As White House chief of staff, Klain will serve as gatekeeper to the Oval Office, managing the president’s daily schedule and the White House staff. His role does not require confirmation by the Senate.Treasury Secretary: Janet YellenYellen, 74, is one of Biden’s most experienced cabinet picks. In 2014 she became the first woman to chair the Federal Reserve, a role she held until 2018. Trump did not appoint her to a second term.Prior to that, she was vice-chair at the bank from 2010-2014 and president of the San Francisco branch of the Federal Reserve from 2004 to 2010. From 1997 to 1999 she chaired former president Bill Clinton’s Council of Economic Advisers and from 1994 to 1997 she sat on the Federal Reserve’s Board of Governors.She is professor emeritus at the University of California at Berkeley.National Security Adviser: Jake SullivanSullivan, 44, is seen as particularly close to Hillary Clinton, having been her chief foreign policy adviser during her 2016 presidential campaign.He was director of policy planning at the State Department and Clinton’s deputy chief of staff during her 2009-2013 tenure at the State Department.When Clinton stood down as secretary of state at the end of Obama’s first term, Sullivan became national security adviser to then vice president Biden.He was previously director of policy planning at the State Department.Attorney General: Merrick GarlandGarland, 68, has been a federal appeals court judge since 1997. In 2016 Obama nominated him to fill the vacancy on the Supreme Court after the death of former Justice Antonin Scalia. But Republican Senate Majority Leader Mitch McConnell blocked his nomination by declining to consider his appointment in a presidential election year.Garland is viewed as a moderate in the US jurisprudential divide between originalists such as former Justice Scalia and exponents of the living constitution theory such as the late Justice Ruth Bader Ginsburg.He is currently the Chief Judge of the US Court of Appeals for the Washington, DC Circuit.Defence Secretary: Lloyd AustinAustin, 67, is a retired four-star general who served as the head of the United States Central Command (CENTCOM) – the all-important military command encompassing the Middle East – from 2013 to 2016, after serving as the army’s vice-chief of staff from 2012 to 2013.Austin would need a waiver from a provision of the 1947 National Security Act decreeing that former military members must wait seven years before being appointed defence secretary – a clause designed to keep politics and the military separate. However, a precedent for this was set when Trump appointed former general James Mattis to the Pentagon in 2016, three years after Mattis stepped down as head of CENTCOM.Ambassador to the UN: Linda Thomas-GreenfieldThomas-Greenfield, 69, was Obama’s chief diplomat on Africa between 2013 and 2017, playing a major role in the US response to the Ebola outbreak in West Africa from 2013 to 2016.This followed decades of experience in foreign affairs. She joined the Foreign Service in 1982, holding postings in countries including Switzerland, Nigeria, Kenya and Pakistan and serving as ambassador to Liberia from 2008-2012.CIA Director: William BurnsA veteran diplomat, Burns, 64, preceded Blinken as Obama’s deputy secretary of state from 2011 to 2014.

She served as national security adviser throughout Obama’s second term, from 2013-2017, and ambassador to the UN in the first, from 2009-2013.Rice’s foreign policy experience dates back to the Clinton administration, in which she was assistant secretary of state for African affairs from 1997 to 2001.Prior to that, she worked as a management consultant at McKinsey and as an aide to the unsuccessful 1988 Democratic presidential candidate Michael Dukakis.Office of Management and Budget Director: Neera TandenSince 2011, Tanden has been president of the Center for American Progress, the liberal American think tank she helped found in 2003.As assistant to Obama’s then secretary of health and human services Kathleen Sibelius, Tanden played a major role in the development of the Affordable Care Act, known as Obamacare, which became law in 2010.Tanden was Hillary Clinton’s policy director in her unsuccessful 2008 run for the Democratic nomination.Secretary of Homeland Security: Alejandro MayorkasMayorkas was deputy secretary of homeland security under Obama from 2013 to 2016, preceded by another senior role in the department as director of US Citizenship and Immigration Services from 2009 to 2013.Before that, Mayorkas became the youngest United States Attorney in 1998, working in this prosecutorial role with responsibility for California’s Central District until 2001.Secretary of Health and Human Services: Xavier BecerraBecerra has been attorney general of the largest US state, California, since 2017, the latest in a string of powerful roles in the Democratic Party.He was a Congressman representing a central Los Angeles seat from 1993 to 2017, taking the role of chairman of the House Democratic Caucus from 2013 to 2017.

He came in second to Sanders in the New Hampshire primary.Biden was humiliated in Iowa and New Hampshire, coming in fourth. But he staged a remarkable comeback with a resounding victory in South Carolina – supplanting Buttigieg as the frontrunner of the moderates. After that result, Buttigieg dropped out and backed Biden.Secretary of Education: Miguel CardonaCardona has been Connecticut’s education commissioner since 2019 after a career as a primary school teacher – allowing Biden to fulfil his goal of putting a former teacher in charge of the department.Secretary of Agriculture: Tom VilsackThe nominations of figures like Blinken, Sullivan and Rice show Biden’s desire to create some continuity with the Obama years. Vilsack’s nomination is even more emblematic of this link: he was secretary of agriculture during the entirety of Obama’s tenure – the only one of his cabinet appointees to stay in office for the whole eight years.Before that, Vilsack was governor of Iowa from 1999 to 2007.Secretary of the Interior: Deb HaalandHaaland has been a Congresswoman representing New Mexico’s 1st district – which encompasses most of Albuquerque and its suburbs – since 2019.

Bush.He also succeeded Hillary Clinton as Obama’s secretary of state, in charge of US foreign policy from 2013 to 2017, playing a notable role in developing the Paris climate change agreement signed in 2015.
