President-elect Trump is assembling his Cabinet and senior staff for his second term in the White House before taking office in January.

Trump must nominate leaders for 15 government agencies and other top administration jobs that require Senate confirmation, along with appointing senior staff.

Here’s a look at who has been tapped to serve so far. 

Cabinet

Secretary of State: Marco Rubio

The Republican Florida senator is seen as a foreign policy hawk who is tough on China and Iran. His selection to serve as Trump’s top diplomat completes a drastic turnaround from 2016, when the two were fierce rivals in the GOP presidential primary. Rubio was also in consideration for Trump’s running mate this year, before he selected Sen. JD Vance (R-Ohio).

Attorney general: Matt Gaetz

The Florida Republican just reelected to his fifth term in the House is known for his bombastic style. Gaetz is a loyal congressional ally of Trump who himself was the subject of a Justice Department investigation. Trump said in naming Gaetz as his pick to lead the department that he would “end Weaponized Government, protect our Borders, dismantle Criminal Organizations and restore Americans’ badly-shattered Faith and Confidence in the Justice Department.”

Defense secretary: Pete Hegseth

Hegseth served as an officer in the Army National Guard and did tours in Afghanistan and Iraq, earning two Bronze Stars. He is currently a co-host for “Fox & Friends Weekend.” Trump has pledged to fire generals involved in the 2021 Afghanistan withdrawal and to eliminate “woke” initiatives that focus on diversity and equity in the military. The choice of Hegseth came as a surprise even to some Trump allies, as he was not among the names considered in the running for the job.

Homeland Security secretary: Kristi Noem

Noem, a Republican who has served as South Dakota governor since 2019, is a loyal Trump ally and would help oversee his immigration crackdown in a second term. She was also in consideration for Trump’s running mate before early excerpts of her book revealed she killed her hunting dog 20 years ago.

Director of national intelligence: Tulsi Gabbard

Gabbard, a four-term Democratic congresswoman from Hawaii who ran against President Biden in the 2020 primaries, left the party in 2022 but did not officially become a Republican until earlier this year. She is a National Guard veteran who served two tours of duty in the Middle East and has long been critical of the Democratic establishment, especially of the country’s engagement in wars in that region. She is on Trump’s transition team.

CIA director: John Ratcliffe

Ratcliffe, the former head of national intelligence in the last Trump administration, was selected to lead the CIA. He previously served as a congressman from Texas; Trump, in a statement, called him “a warrior for Truth and Honesty with the American Public.” Ratcliffe also served as a member of Trump’s impeachment team during the Democrats’ first effort to boot the then-president from office.

Environmental Protection Agency director: Lee Zeldin

Trump’s selection to lead the EPA is Zeldin, a Republican former New York congressman and gubernatorial candidate who was an outspoken defender of the 45th president during his first impeachment trial in 2020. Trump mentioned Zeldin’s legal background, a sign he will likely lean on the EPA to roll back environmental regulations.

United Nations ambassador: Elise Stefanik

The House GOP conference chair who just won her fifth term representing an upstate New York district, Stefanik has limited diplomatic experience but has been an outspoken critic of the United Nations and a staunch ally of Israel.

Ambassador to Israel: Mike Huckabee

Huckabee, the former Arkansas governor from 1996-2007, was selected for a major diplomatic role amid heightened tensions in the Middle East.  Huckabee has never held a diplomatic post previously but has at times weighed in on the war in Gaza, including when he told NewsNation that he did not see a reason to support an Israel-Hamas cease-fire and that the only way to end the war would be to eradicate the terrorist group.

Trump has urged Israel to “finish the problem” in the fight against Hamas following its October 2023 attacks, even as he has been critical of how the country has carried out the military campaign.

White House

Chief of staff: Susie Wiles

Wiles spent the past two years co-running Trump’s campaign and is well-respected as a political operative. She will become the first woman to serve as a White House chief of staff. 

Wiles, among the people Trump thanked after his 2024 victory, was largely a behind-the-scenes figure during his run. She has also worked for Sen. Rick Scott (R-Fla.) and Florida Gov. Ron DeSantis (R) and was a deputy director during former President Reagan’s 1980 campaign.

Deputy chief of staff for policy: Stephen Miller

Miller was one of Trump’s closest advisers during his first term and was an architect of policies like a ban on travel from several Muslim-majority countries and family separation. He is expected to lead efforts to enact Trump’s immigration crackdown in a second term.

Border czar: Tom Homan

A former Immigration and Customs Enforcement director, Homan was named Trump’s “border czar,” tasked with cracking down on immigration and overseeing the “the Southern Border, the Northern Border, all Maritime, and Aviation Security,” according to a statement from the president-elect.

Homan has said he will crank up workplace raids as a way to address labor and sex trafficking and will prioritize “public safety threats and national security threats” for deportation as border czar. He was an early proponent of the “zero tolerance” policy that separated more than 4,000 children from their parents in the first Trump administration, and recently said “families can be deported together” while discussing plans for the upcoming term.

National security adviser: Mike Waltz

Waltz, an Army veteran who was the first Green Beret elected to Congress, will serve as Trump’s top national security official, leaving the House after representing Florida since 2019.

The Republican congressman has called for Europe to do more to support Ukraine and for the U.S. to be more stringent with its support, aligning with a key foreign policy goal of the president-elect. He has also been a staunch critic of the Biden administration’s 2021 withdrawal from Afghanistan.

White House counsel: Bill McGinley

McGinley will return to the White House under Trump as his counsel. He was Cabinet secretary during Trump’s first administration and has also served as general counsel at the National Republican Senatorial Committee.

Trump, in a statement, called McGinley “a smart and tenacious lawyer who will help me advance our America First agenda while fighting for election integrity and against the weaponization of law enforcement” and said he played a major role in the GOP victory in the 2024 election.

Middle East envoy: Steven Witkoff

Witkoff, a New York businessman, will serve as special envoy to the Middle East, a role Trump said in a statement will involve him being a “voice for peace.” He is a longtime friend of the president-elect, is known as a real estate tycoon and is chair and CEO of Witkoff.

Department of Government Efficiency: Elon Musk, Vivek Ramaswamy

Trump announced Musk, a billionaire backer, and Ramaswamy, a former GOP primary rival who endorsed Trump after dropping his own bid, would lead an effort to slash government spending and regulations. They are expected to conclude their work by July 4, 2026, just a few months before the midterm elections. Trump said the effort would partner with the Office of Management and Budget but would provide guidance from “outside of Government.” Musk in particular has extensive financial holdings with government contractors that could complicate an official government job.

Possible picks for other posts:

Thomas Barrack, potential US special envoy

Mr Barrack, an American-Lebanese billionaire, is a longtime ally of Mr Trump. Mr Barrack, who chaired Mr Trump’s 2017 inaugural committee, had faced legal scrutiny over his foreign dealings, raising questions about his influence on US policy. He was acquitted of charges alleging he acted as an unregistered agent of a foreign government under the first Trump presidency. Known for his strong ties to the Middle East, the California-based investor may be considered for a role as a US special envoy.

Joel Rayburn, potential foreign policy adviser

Joel Rayburn, a retired US Army colonel and Middle East specialist, is an experienced diplomat and intelligence officer with a background in US foreign policy towards the region. Mr Rayburn previously served as the US special envoy for Syria and deputy assistant secretary for Levant affairs during the first Trump administration, where he played a vital role in formulating and introducing US strategies on Syria, including countering ISIS and curbing Iranian influence. Known for his extensive regional knowledge, Mr Rayburn has cultivated strong ties with Middle Eastern allies.

John Paulson, potential treasury secretary

John Paulson, billionaire hedge fund manager and significant donor to Mr Trump, is among the leading candidates for treasury secretary. Known for his advocacy of tax cuts and deregulation, Mr Paulson has expressed interest in the role, sources told Reuters. His stance on economic policy aligns with other probable members of Mr Trump’s economic team, favouring targeted tariffs to protect US national security and address trade practices. Mr Paulson's April fund-raiser brought in more than $50 million for Mr Trump, underscoring his influence within the former president's circle.

Robert F Kennedy, Jr, potential health adviser

Mr Kennedy, long dismissed as an anti-vax conspiracy theorist by the Democrats, will now probably be invited into a Trump administration as a health adviser. He has said he wants to ban fluoride – long credited with saving children from dental cavities – from drinking water and Mr Trump has seemed receptive to his idea of increased scrutiny of vaccines. Mr Kennedy ran as a third-party candidate in this election before announcing his support for Mr Trump.
