Washington CNN  — 

Several of President-elect Joe Biden’s nominees would make history if confirmed by the United States Senate to serve in top roles in his incoming administration.

Since winning the election, Biden has made moves to carry out his campaign promise of building an administration that looks like and reflects the diversity of America. Vice President-elect Kamala Harris has already shattered a monumental barrier by becoming the first woman elected Vice President.

Here are other people who would be historic firsts, if confirmed by the Senate:

First Black Deputy Secretary of the Treasury

Adewale “Wally” Adeyemo

Wally Adeyemo

Adeyemo currently serves as the president of the Obama Foundation. Adeyemo served during the Obama administration as the President’s senior international economic adviser, and also served as deputy national security adviser, deputy director of the National Economic Council, the first chief of staff of the Consumer Financial Protection Bureau and senior adviser and deputy chief of staff at the Department of the Treasury.

First Black Secretary of Defense

Lloyd Austin

WASHINGTON, DC - SEPTEMBER 16:  Gen. Lloyd Austin III, commander of U.S. Central Command, testifies before the Senate Armed Services Committee about the ongoing U.S. military operations to counter the Islamic State in Iraq and the Levant (ISIL) during a hearing in the Dirksen Senate Office Building on Capitol Hill September 16, 2015 in Washington, DC. Austin said that slow progress was still being made against ISIL but there have been setbacks, including the ambush of U.S.-trained fighters in Syria and the buildup of Russian forces in the country.

Austin would make history as the first Black person to lead the Pentagon if confirmed by the Senate. Austin is a retired Army general and is the former commander of the US Central Command. He has worked closely with Biden in the past. While Biden was vice president, Austin served as the vice chief of staff of the Army and commanding general of US forces in Iraq, and later the commander of CENTCOM. Biden and Austin had discussions on a range of issues, including those in the Middle East and Central and South Asia. Austin would need a congressional waiver to be confirmed for the civilian post because federal law requires seven years of retirement from active duty before taking on the role. Austin retired from active-duty service only four years ago.

Becerra would be the first Latino to lead the Department of Health and Human Services if confirmed by the Senate. He currently serves as California’s attorney general, and is the first Latino to hold that office in the history of the state. Becerra has been a chief defender of the Affordable Care Act in court. As the Trump administration and a coalition of Republican state attorneys general fight to invalidate the landmark health reform law, Becerra has led a group of Democratic attorneys general arguing why the law remains valid. Becerra served 12 terms in Congress as a member of the US House of Representatives and held several leadership posts. He was the chair of the House Democratic Caucus, the chair of the Congressional Hispanic Caucus and the ranking member of the Ways and Means Subcommittee on Social Security. He was also the first Latino to serve as a member of the Ways and Means Committee. Becerra also served one term in the California Legislature and is a former deputy attorney general with the California Department of Justice.

Buttigieg would make history if confirmed by the Senate as the first out LGBTQ Cabinet secretary approved by the chamber. The former South Bend, Indiana, mayor is the youngest member named so far in Biden’s Cabinet, at 38 years old. He is also the only one of Biden’s former Democratic presidential opponents to be named so far as a Cabinet secretary nominee. The former mayor is seen as a rising star in the Democratic Party and rose to national prominence during the 2020 Democratic primary. Once an unknown mayor of a small city, Buttigieg became a top presidential contender and made history as the first LGBTQ presidential candidate to win primary delegates from a major party. During his tenure as mayor, Buttigieg in 2014 deployed to Afghanistan as an intelligence officer. After returning from his deployment, Buttigieg in 2015 came out as gay in an essay for the South Bend Tribune while serving as mayor. Later that year, Buttigieg won reelection.
