(CNN) — President-elect Joe Biden is set to announce who will serve in top roles in his administration in the coming days and weeks.

He has already announced that Ron Klain, one of his most trusted campaign advisers, will serve as his incoming chief of staff. And Jen O’Malley Dillon, Biden’s campaign manager, and Rep. Cedric Richmond of Louisiana, a co-chair of Biden’s transition team and presidential campaign, will serve in top roles in the White House.

The Biden campaign also announced several White House senior staff members on November 17, including: Mike Donilon, chief strategist for the Biden campaign; Steve Ricchetti, chairman of the Biden campaign; Dana Remus, general counsel to the Biden campaign; Julie Rodriguez, deputy campaign manager on the Biden campaign; and Annie Tomasini, Biden’s traveling chief of staff. Members of soon-to-be first lady Jill Biden’s office were also announced.

Each of Biden’s Cabinet nominees will need to be confirmed by the US Senate, which is currently controlled by Republicans. Two runoff elections in Georgia on January 5 could determine which party controls the chamber and impact the Cabinet confirmation process.

The Cabinet includes the vice president and the heads of 15 executive departments: Agriculture, Commerce, Defense, Education, Energy, Health and Human Services, Homeland Security, Housing and Urban Development, Interior, Justice, Labor, State, Transportation, Treasury and Veterans Affairs.

Several key positions also have Cabinet-level rank: White House chief of staff, Environmental Protection Agency administrator, Office of Management & Budget director, United States Trade Representative ambassador, Council of Economic Advisers chairman and Small Business Administration administrator.

This list will be updated based on conversations with Biden allies and advisers and Democrats with knowledge of the matter.

Here’s who has been mentioned in conversations about potential top roles in the Biden administration:

Secretary of State

Antony Blinken

Blinken served in the Obama administration as the deputy secretary of state, assistant to the president and principal deputy national security adviser. He served as the national security adviser to then-Vice President Biden and deputy assistant to the president during Obama’s first term. He has been a senior fellow at the Center for Strategic and International Studies, and the Democratic staff director at the US Senate Committee on Foreign Relations.

During the Clinton administration, Blinken served as a member of the National Security Council staff at the White House, and held roles as the special assistant to the president, senior director for European affairs, and senior director for speechwriting and then strategic planning. He was Clinton’s chief foreign policy speechwriter.

Blinken is also being considered as national security adviser.

Chris Coons

Coons currently occupies the same Delaware Senate seat that Biden held for decades. A longtime Biden ally, Coons was one of the first members of Congress to endorse the former vice president when he declared his 2020 presidential candidacy. Coons sits on the following committees in the Senate: Foreign Relations, Appropriations, Judiciary, Small Business & Entrepreneurship and Select Committee on Ethics. Throughout his Senate career, Coons has been known for working across the aisle and forging strong relationships with high-profile Republicans who shared common interests.

Susan Rice

Rice served in the Obama administration as UN ambassador and national security adviser. She served in Clinton’s administration as the special assistant to the president and senior director for African affairs at the White House, the assistant secretary for the Bureau of African Affairs at the State Department and the director of international organizations and peacekeeping at the National Security Council. Rice was one of a handful of women on Biden’s shortlist for a running mate.

Rice at one point was thought to be the clear choice to succeed Hillary Clinton as secretary of state, but in 2012 withdrew her name from consideration to avoid a bitter Senate confirmation battle. Rice was the target of Republican criticism after comments she made on Sunday morning TV shows defending the Obama administration’s handling of the September 11, 2012, attacks on the Benghazi consulate that killed Ambassador Chris Stevens and three other Americans.

Secretary of the Treasury

Lael Brainard

Brainard currently serves as a member of the Board of Governors of the Federal Reserve System. She previously served as the Under Secretary of the US Department of the Treasury and counselor to the secretary of the Treasury during the Obama administration. Brainard was the US representative to the G-20 Finance Deputies and G-7 Deputies and was a member of the Financial Stability Board. During the Clinton administration, Brainard served as the deputy national economic adviser and deputy assistant to the President. She also served as Clinton’s personal representative to the G-7/G-8.

If chosen, the Federal Reserve governor would be the first woman to hold the powerful position. Brainard is not quite a consensus pick. Party progressives have other favorites, but neither would her nomination set off the kind of internal ideological war the incoming administration surely wants to avoid.

Sarah Bloom Raskin

Raskin was the deputy secretary of the US Department of the Treasury during the Obama administration. She was previously a governor of the Federal Reserve Board. Prior to joining the Federal Reserve Board, Raskin was the commissioner of financial regulation for the state of Maryland.

Outside of Sen. Elizabeth Warren, Raskin, a former deputy secretary at the department, would be the top choice for most progressives. That she is less well known to the wider political world could also work in favor.

Secretary of Defense

Michèle Flournoy

If chosen and confirmed, Flournoy would be the first female secretary of defense. She served as the under secretary of defense for policy under Obama. Prior to her confirmation, Flournoy helped lead Obama’s transition team at the Defense Department. During the mid-1990’s, she served as principal deputy assistant secretary of defense for strategy and threat reduction, as well as deputy assistant secretary of defense for strategy. She co-founded the Center for a New American Security, a bipartisan think tank, and WestExec Advisors, a strategic advisory firm. Flournoy was a senior advisor at the Center for Strategic and International Studies.

Secretary of Veterans Affairs

Patrick Murphy

Murphy, America’s first Iraq War veteran elected to Congress, represented the state’s 8th Congressional District. He served on the House Armed Services, Select Intelligence and Appropriations committees. He later served as the 32nd under secretary of the Army under President Barack Obama.

Secretary of Homeland Security 

Alejandro Mayorkas

Mayorkas was deputy secretary of Homeland Security during the Obama administration, and served as the director of the Department of Homeland Security’s United States Citizenship and Immigration Services. While at USCIS, Mayorkas oversaw the implementation of the Deferred Action for Childhood Arrivals program, which was an executive action under Obama that protected young undocumented immigrants who came to the US as children from deportation. President Donald Trump moved to end the Deferred Action for Childhood Arrivals program in 2017 and was ultimately blocked by the Supreme Court from doing so.

Lisa Monaco

Monaco played a critical role in Biden’s vice presidential selection committee, and served as Homeland Security and counterterrorism advisor to Obama. Prior to that job, Monaco served as an assistant attorney general for national security at the Department of Justice, and was a chief of staff to then-Director of the FBI Robert S. Mueller III.

Attorney General 

Jeh Johnson

Johnson was the Secretary of the Department of Homeland Security from 2013 to 2017 under the Obama administration. Previously, Johnson had been appointed by Obama to be general counsel of the Department of Defense. In the Clinton administration, Johnson served as general counsel of the Department of the Air Force.

Doug Jones

Jones is the junior United States Senator from Alabama. He lost his reelection bid earlier this month to Republican Tommy Tuberville. President Bill Clinton appointed Jones as US Attorney for the Northern District of Alabama, and Jones was the lead prosecutor suing KKK members responsible for the 16th Street Baptist Church bombing. Jones was also involved in the prosecution of Eric Rudolph, whose 1998 attack on a Birmingham abortion clinic killed an off-duty police officer.

Sally Yates

Yates was fired by Trump from her role as acting attorney general. The stunning move came after CNN and other outlets reported that Yates told Justice Department lawyers not to make legal arguments defending Trump’s executive order on immigration and refugees. Trump’s executive order, signed in January 2017, barred citizens of seven Muslim-majority countries from entering the United States for the following 90 days, suspended the admission of all refugees for 120 days and indefinitely suspended the Syrian refugee program. The executive order was later blocked by a federal judge, but the Supreme Court ultimately upheld a revised version of the ban.

Yates had been appointed by Obama and was set to serve until Trump’s nominee for attorney general was confirmed.

Secretary of the Interior

Deb Haaland

Haaland is a congresswoman from New Mexico, and is one of the first Native American women to serve in Congress. Biden has said he wants an administration that looks like the country. Haaland, the vice chair of the House Natural Resources Committee, would be the first Native American Cabinet secretary if she were to get an offer and accept it. Haaland also leads the Subcommittee on National Parks, Forests and Public Lands.

Tom Udall

Udall is the senior senator from New Mexico. He previously was the US representative for the state’s 3rd Congressional District. In 1990, hr was elected New Mexico attorney general, and was reelected in 1994. Udall also was chief counsel to the New Mexico Department of Health and Environment, and he fought for stronger environmental and health protections.

Secretary of Commerce

Andrew Yang

Yang is an entrepreneur and former 2020 Democratic presidential candidate. He rose from obscurity to become a highly-visible candidate, and his supporters are sometimes referred to as the “Yang Gang.” His presidential campaign was centered around the idea of universal basic income, and providing every US citizen with $1,000 a month, or $12,000 a year. His campaign slogan was “MATH,” or “Make America Think Harder.” Yang joined CNN as a political commentator in February, after dropping out of the presidential race.

Secretary of Labor

Andy Levin

Levin is a popular progressive who is also growing his base of support with labor leaders, including at the Communications Workers of America. The United Auto Workers and National Nurses United unions are backing the Michigan congressman for the role. Like Walsh, Levin has a background as an organizer with major unions. But he also has credibility with climate activists for having helped create Michigan’s Green Jobs Initiative.

Sara Nelson

Nelson is the international president of the Association of Flight Attendants-CWA. She cemented her image as a rising star of the labor movement during a prolonged government shutdown that stretched from December 2018 to January 2019. During the shutdown, Nelson appeared on cable television and used social media to warn of the dangers of not paying airport workers, and called for a general strike at an AFL-CIO gathering in January.

Bernie Sanders

Sanders is reaching out to potential supporters in labor to ask for their support as he mounts a campaign for the job. But he is viewed as a long shot and so far has received mix reactions from labor leaders. In his public comments before and after the election, he focused on a 100-day agenda for the Congress. But with Democrats likely needing to win both Georgia runoffs to take control of the Senate, running a powerful agency might have become more appealing.

Sanders told CNN’s Wolf Blitzer on Wednesday that if Biden asked him to join his Cabinet as Labor secretary, he would accept the nomination. “If I had a portfolio that allowed me to stand up and fight for working families, would I do it? Yes, I would,” Sanders said.

Marty Walsh

Walsh is the mayor of Boston, and is AFL-CIO President Richard Trumka’s pick for the job, a big endorsement in what could soon turn into a contentious debate between moderate Democrats and progressives, who will favor Sen. Bernie Sanders or Michigan Rep. Andy Levin. Walsh grew up in a union family and became a top Boston labor leader before being elected mayor.

Health and Human Services Secretary

Michelle Lujan Grisham

Grisham was the first Democratic Latina to be elected governor in the US. Grisham was elected to Congress in 2011 and served three terms representing New Mexico’s 1st congressional district. She was chair of the Congressional Hispanic Caucus. Grisham was under consideration to serve as Biden’s vice president.

Vivek Murthy

Murthy, a doctor of internal medicine, is the co-chair of Biden’s coronavirus advisory board. He previously served as the US surgeon general after being nominated by Obama. He resigned in April 2017 at the request of the Trump administration. He was confirmed by the Senate after facing opposition from Senate Republicans for calling to treat gun violence as a public health issue.

Gina Raimondo

Raimondo is the first woman governor of Rhode Island. She previously served as the general treasurer of the state. Raimondo was elected governor in 2014 and won reelection in 2018. That same year, Raimondo was elected to serve as the chairwoman of the Democratic Governors Association. Raimondo was among the women considered for Biden’s running mate.

Department of Housing and Urban Development Secretary

Keisha Lance Bottoms

Bottoms is the mayor of Atlanta and is a rising star of the Democratic Party. Bottoms stepped into the national spotlight when she denounced vandalism in her city as “chaos” after demonstrations over the death of George Floyd, a Black man who was killed by police in Minneapolis. Bottoms is a former judge and city council member. She was considered as a potential running mate for Biden.

Transportation Secretary 

Eric Garcetti

Garcetti is the mayor of Los Angeles. He was first elected to the role in 2013 and won reelection in 2017. He was previously a member of the Los Angeles City Council and served as council president. Garcetti is the first Jewish mayor of Los Angeles.

She also chaired New York City’s Municipal Labor Committee.

Administrator of the Environmental Protection Agency

Jay Inslee

Inslee is the governor of Washington state, and previously served in the US House of Representatives. He was a Democratic presidential candidate in the 2020 election. Inslee is dedicated to addressing climate change and other environmental issues, and made the environment the central focus of his 2020 presidential bid. While in the US House of Representatives, he served on the House Committee on Energy and Commerce and on the House Select Committee on Energy Independence and Global Warming.

UN ambassador

Pete Buttigieg

Buttigieg is the former mayor of South Bend, Indiana, and a former 2020 Democratic presidential candidate. Buttigieg’s presidential bid was historic — he was the first out gay man to launch a competitive campaign for president, and he broke barriers by becoming the first gay candidate to earn primary delegates for a major party’s presidential nomination.

White House Press Secretary

Kate Bedingfield
