President-elect Donald Trump is filling key posts in his second administration, and it’s shaping up much differently than his first. He’s prioritizing loyalists for top jobs.

Trump was bruised and hampered by internal squabbles during his initial term in office. Now he appears focused on remaking the federal government in his own image. Some of his choices could face difficult confirmation battles even with Republicans in control of the U.S. Senate.

Here’s a look at whom he has selected so far.

Cabinet nominees:

SECRETARY OF STATE: Marco Rubio

Trump named Florida Sen. Marco Rubio to be secretary of state, making the critic-turned-ally his choice for top diplomat.

Rubio, 53, is a noted hawk on China, Cuba and Iran, and was a finalist to be Trump’s running mate on the Republican ticket last summer. Rubio is the vice chairman of the Senate Intelligence Committee and a member of the Senate Foreign Relations Committee.

The announcement punctuates the hard pivot Rubio has made with Trump, whom the senator once called a “con man” during his unsuccessful campaign for the 2016 Republican presidential nomination.

Their relationship improved dramatically while Trump was in the White House. And as Trump campaigned for the presidency a third time, Rubio cheered his proposals. For instance, Rubio, who more than a decade ago helped craft immigration legislation that included a path to citizenship for people in the U.S. illegally, now supports Trump’s plan to use the U.S. military for mass deportations.

ATTORNEY GENERAL: Matt Gaetz

Trump said Wednesday he will nominate Florida Rep. Matt Gaetz to serve as his attorney general, naming a loyalist in the role of the nation’s top prosecutor.

In selecting Gaetz, 42, Trump passed over more established lawyers whose names had been mentioned as being contenders for the job.

“Matt will end Weaponized Government, protect our Borders, dismantle Criminal Organizations and Restore Americans’ badly-shattered Faith and Confidence in the Justice Department,” Trump said in a statement.

Gaetz resigned from Congress after Trump announced him. The House Ethics Committee has been investigating an allegation that Gaetz paid for sex with a 17-year-old, though that probe effectively ended when he resigned. Gaetz has denied any wrongdoing.

DIRECTOR OF NATIONAL INTELLIGENCE: Tulsi Gabbard

Former Hawaii Rep. Tulsi Gabbard has been tapped by Trump to be director of national intelligence, another example of Trump prizing loyalty over experience.

Gabbard, 43, was a Democratic House member who unsuccessfully sought the party’s 2020 presidential nomination before leaving the party in 2022. She endorsed Trump in August and campaigned often with him this fall, and she’s been accused of echoing Russian propaganda.

Gabbard, who has served in the Army National Guard for more than two decades, deploying to Iraq and Kuwait, would come to the role as an outsider compared to her predecessor. The current director, Avril Haines, was confirmed by the Senate in 2021 following several years in a number of top national security and intelligence positions.

DEFENSE SECRETARY: Pete Hegseth

Hegseth, 44, was a co-host of Fox News Channel’s “Fox and Friends Weekend” and has been a contributor with the network since 2014. He developed a friendship with Trump, who made regular appearances on the show.

Hegseth served in the Army National Guard from 2002 to 2021, deploying to Iraq in 2005 and Afghanistan in 2011. He has two Bronze Stars. However, Hegseth lacks senior military and national security experience. If confirmed by the Senate, he would inherit the top job during a series of global crises — ranging from Russia’s war in Ukraine and the ongoing attacks in the Middle East by Iranian proxies to the push for a cease-fire between Israel, Hamas and Hezbollah and escalating worries about the growing alliance between Russia and North Korea.

Hegseth is also the author of “The War on Warriors: Behind the Betrayal of the Men Who Keep Us Free,” published earlier this year.

COMMERCE SECRETARY: Howard Lutnick

Lutnick heads up the brokerage and investment bank Cantor Fitzgerald and is a cryptocurrency enthusiast. He is co-chair of Trump’s transition operation, charged along with Linda McMahon, a former wrestling executive who previously led Trump’s Small Business Administration, with helping the president-elect build a Cabinet for his second administration.

As commerce secretary, Lutnick would play a key role in carrying out Trump’s plans to raise and enforce tariffs. He would oversee a sprawling Cabinet department whose oversight ranges from funding new computer chip factories and imposing trade restrictions to releasing economic data and monitoring the weather.

HOMELAND SECURITY SECRETARY: Kristi Noem

Noem is a well-known conservative who used her two terms as South Dakota’s governor to vault to a prominent position in Republican politics.

During the COVID-19 pandemic, Noem did not order restrictions that other states had issued and instead declared her state “open for business.” Trump held a fireworks rally at Mount Rushmore in July 2020 in one of the first large gatherings of the pandemic.

More recently, Noem faced sharp criticism for telling a story in her memoir about shooting and killing her dog.

She is set to lead a department crucial to the president-elect’s hardline immigration agenda as well as other missions. Homeland Security oversees natural disaster response, the U.S. Secret Service and Transportation Security Administration agents who work at airports.

CIA DIRECTOR: John Ratcliffe

Ratcliffe, a former U.S. House member from Texas, was director of national intelligence during the final year and a half of Trump’s first term, leading the U.S. government’s spy agencies during the coronavirus pandemic.

If confirmed, Ratcliffe will have held the highest intelligence positions in the U.S.

HEALTH AND HUMAN SERVICES SECRETARY: Robert F. Kennedy Jr.

Kennedy ran for president as a Democrat, then as an independent, and then endorsed Trump. He’s the son of Democratic icon Robert Kennedy, who was assassinated during his own presidential campaign.

The nomination alarmed people who are concerned about his record of spreading unfounded fears about vaccines. For example, he has long advanced the debunked idea that vaccines cause autism.

TRANSPORTATION SECRETARY: Sean Duffy

Duffy is a former House member from Wisconsin who was one of Trump’s most visible defenders on cable news. Duffy served in the House for nearly nine years, sitting on the Financial Services Committee and chairing the subcommittee on insurance and housing. He left Congress in 2019 for a TV career and has been the host of “The Bottom Line” on Fox Business.

Before entering politics, Duffy was a reality TV star on MTV, where he met his wife, “Fox and Friends Weekend” co-host Rachel Campos-Duffy. They have nine children.

VETERANS AFFAIRS SECRETARY: Doug Collins

Collins is a former Republican congressman from Georgia who gained recognition for defending Trump during his first impeachment trial, which centered on U.S. assistance for Ukraine. Trump was impeached for urging Ukraine to investigate Joe Biden in 2019 during the Democratic presidential nomination, but he was acquitted by the Senate.

Collins has also served in the armed forces himself and is currently a chaplain in the United States Air Force Reserve Command.

INTERIOR SECRETARY: Doug Burgum

The governor of North Dakota, once little-known outside his state, is a former Republican presidential primary contender who endorsed Trump and then spent months traveling to drum up support for Trump after dropping out of the race.

Burgum was a serious contender to be Trump’s vice presidential choice this summer. The two-term governor was seen as a possible pick because of his executive experience and business savvy. Burgum also has close ties to deep-pocketed energy industry CEOs.

Trump initially announced his choice of Burgum while addressing a gala at his Mar-a-Lago club in Florida. His formal announcement the following day said he wanted Burgum to be Interior secretary and chairman of a new National Energy Council. Burgum will also have a seat on the National Security Council, which would be a first for the Interior secretary.

ENERGY SECRETARY: Chris Wright

A campaign donor and CEO of Denver-based Liberty Energy, Write is a vocal advocate of oil and gas development, including fracking — a key pillar of Trump’s quest to achieve U.S. “energy dominance” in the global market.

Wright also has been one of the industry’s loudest voices against efforts to fight climate change. He said the climate movement around the world is “collapsing under its own weight.” The Energy Department is responsible for advancing energy, environmental and nuclear security of the United States.

Wright also won support from influential conservatives, including oil and gas tycoon Harold Hamm. Hamm, executive chairman of Oklahoma-based Continental Resources, a major shale oil company, is a longtime Trump supporter and adviser who played a key role on energy issues in Trump’s first term.

EDUCATION SECRETARY: Linda McMahon

McMahon, a billionaire professional wrestling mogul, would be making a return appearance in a second Trump administration. She led the Small Business Administration from 2017 to 2019 during Trump’s first term and twice ran unsuccessfully in Connecticut as a Republican candidate for the U.S. Senate. She served on the Connecticut Board of Education for a year starting in 2009 and has spent years on the board of trustees for Sacred Heart University. She has expressed support for charter schools and school choice.

ENVIRONMENTAL PROTECTION AGENCY ADMINISTRATOR: Lee Zeldin

Zeldin does not appear to have any experience in environmental issues, but is a longtime supporter of the former president. The 44-year-old former U.S. House member from New York wrote on X, “We will restore US energy dominance, revitalize our auto industry to bring back American jobs, and make the US the global leader of AI.”

“We will do so while protecting access to clean air and water,” he added.

During his campaign, Trump often attacked the Biden administration’s promotion of electric vehicles, and incorrectly referred to a tax credit for EV purchases as a government mandate. Trump also often told his audiences during the campaign that his administration would “drill, baby, drill,” referring to his support for expanded petroleum exploration.

White House staff:

CHIEF OF STAFF: Susie Wiles

Wiles, 67, was a senior adviser to Trump’s 2024 presidential campaign and its de facto manager.

She has a background in Florida politics, helping Ron DeSantis win his first race for Florida governor. Six years later, she was key to Trump’s defeat of him in the 2024 Republican primary.

Wiles’ hire was Trump’s first major decision as president-elect and one that could be a defining test of his incoming administration considering her close relationship with him. Wiles is said to have earned Trump’s trust in part by guiding what was the most disciplined of Trump’s three presidential campaigns.

Wiles was able to help keep Trump on track as few others have, not by criticizing his impulses, but by winning his respect by demonstrating his success after taking her advice.

NATIONAL SECURITY ADVISER: Mike Waltz

Waltz is a three-term Republican congressman from east-central Florida. A former Army Green Beret, he served multiple tours in Afghanistan and also worked in the Pentagon as a policy adviser when Donald Rumsfeld and Robert Gates were defense chiefs.

He is considered hawkish on China, and called for a U.S. boycott of the 2022 Winter Olympics in Beijing due to its involvement in the origin of COVID-19 and its mistreatment of the minority Muslim Uighur population.

BORDER CZAR: Tom Homan

Homan, 62, has been tasked with Trump’s top priority of carrying out the largest deportation operation in the nation’s history.

He led the U.S. Immigration and Customs Enforcement in Trump’s first administration and said at a conference over the summer that he would be willing to “run the biggest deportation operation this country’s ever seen.”

Democrats have criticized Homan for defending Trump’s “zero tolerance” policy on border crossings during his first administration, which led to the separation of thousands of parents and children seeking asylum at the border.

DEPUTY CHIEF OF STAFF FOR POLICY: Stephen Miller

Miller, an immigration hardliner, was a vocal spokesperson during the presidential campaign for Trump’s priority of mass deportations. The 39-year-old was a senior adviser during Trump’s first administration.

Miller has been a central figure in some of Trump’s policy decisions, notably his move to separate thousands of immigrant families. Trump argued throughout the campaign that the nation’s economic, national security and social priorities could be met by deporting people who are in the United States illegally.

DEPUTY CHIEF OF STAFF: Dan Scavino

Scavino was an adviser in all three of the president-elect’s campaigns, and the transition team referred to him as one of “Trump’s longest serving and most trusted aides.” He will be deputy chief of staff and assistant to the president. He previously ran Trump’s social media profile in the White House during his first administration.

DEPUTY CHIEF OF STAFF: James Blair

Blair was political director for Trump’s 2024 campaign and for the Republican National Committee. He will be deputy chief of staff for legislative, political and public affairs and assistant to the president. Blair was key to Trump’s economic messaging during his winning White House comeback campaign.

DEPUTY CHIEF OF STAFF: Taylor Budowich

Budowich is a veteran Trump campaign aide who launched and directed Make America Great Again, Inc., a super PAC that supported Trump’s 2024 campaign. He will be deputy chief of staff for communications and personnel and assistant to the president.

WHITE HOUSE PRESS SECRETARY: Karoline Leavitt

Leavitt, 27, was Trump’s campaign press secretary and currently a spokesperson for his transition. She would be the youngest White House press secretary in history.

Leavitt worked in the White House press office during Trump’s first term.

In 2022, she ran for Congress in New Hampshire, winning a 10-way Republican primary before losing to Democratic Rep. Chris Pappas.

WHITE HOUSE COUNSEL: William McGinley

McGinley was White House Cabinet secretary during Trump’s first administration, and was outside legal counsel for the Republican National Committee’s election integrity effort during the 2024 campaign.

Ambassadors and envoys and other key posts

SPECIAL ENVOY TO THE MIDDLE EAST: Steven Witkoff

The 67-year-old Witkoff is the president-elect’s golf partner and was golfing with him at Trump’s club in West Palm Beach, Florida, on Sept. 15, when the former president was the target of a second attempted assassination.

Trump also named Witkoff co-chair, with former Georgia Sen. Kelly Loeffler, of his inaugural committee.

AMBASSADOR TO ISRAEL: Mike Huckabee

Huckabee is a staunch defender of Israel and his intended nomination comes as Trump has promised to align U.S. foreign policy more closely with Israel’s interests as it wages wars against the Iran-backed Hamas and Hezbollah.

Huckabee, who ran unsuccessfully for the Republican presidential nomination in 2008 and 2016, has been a popular figure among evangelical Christian conservatives, many of whom support Israel due to Old Testament writings that Jews are God’s chosen people and that Israel is their rightful homeland.

Huckabee has rejected a Palestinian homeland in territory occupied by Israel, calling for a so-called “one-state solution.”

AMBASSADOR TO THE UNITED NATIONS: Elise Stefanik

Stefanik is a U.S. representative from New York and one of Trump’s staunchest defenders going back to his first impeachment.

Elected to the House in 2014, Stefanik was selected by her GOP House colleagues as House Republican Conference chair in 2021, when former Wyoming Rep. Liz Cheney was removed from the post after publicly criticizing Trump for falsely claiming he won the 2020 election. Stefanik, 40, has served in that role ever since as the third-ranking member of House leadership.

Stefanik’s questioning of university presidents over antisemitism on their campuses helped lead to two of those presidents resigning, further raising her national profile.

AMBASSADOR TO NATO: Matthew Whitaker

A former acting attorney general during Trump’s first administration and tight end on the University of Iowa football team, Whitaker, 55, has a background is in law enforcement but not in foreign policy.

A fierce Trump localist, Whitaker, is also a former U.S. attorney in Iowa and served as acting attorney general between November 2018 and February 2019 without Senate confirmation, until William Barr was confirmed for the role. That was when special counsel Robert Mueller’s investigation into Russian election interference was drawing to a close.

Whitaker also faced questions about his past business dealings, including his ties to an invention-promotion company that was accused of misleading consumers.

CENTERS FOR MEDICAID AND MEDICARE SERVICES: Dr. Mehmet Oz

Oz, 64, is a former heart surgeon who hosted “The Dr. Oz Show,” a long-running daytime television talk show. He ran unsuccessfully for the U.S. Senate as the Republican nominee in 2022 and is an outspoken supporter of Trump, who endorsed Oz’s bid for elected office.
