Donald Trump’s new administration: Who has he chosen so far?

President-elect Donald Trump is starting to fill out important positions in his new administration as he prepares for his second stint in the White House.

Here is who Trump has selected so far.

Susie Wiles, chief of staff

Susie Wiles was a senior adviser to Donald Trump's 2024 presidential campaign and its de facto manager.

Wiles has a background in Florida politics and helped Ron DeSantis win his first race for Florida governor. Six years later, she was crucial to Trump's defeat of DeSantis in the 2024 Republican primary.

Trump hiring Wiles was his first major decision as president-elect, with the Associated Press noting that Wiles is said to have earned Trump's trust in part by guiding what was the most disciplined of Trump's three presidential campaigns.

Mike Waltz, national security adviser

Mike Waltz is a retired Army National Guard officer and war veteran, and Donald Trump tapped him to be his national security adviser.

The AP noted that the move would put Waltz at the center of many national security crises, ranging from the ongoing effort to provide weapons to Ukraine and worries about the growing alliance between Russia and North Korea to the attacks in the Middle East by Iran proxies and the push for a cease-fire between Israel and Hamas and Hezbollah.

Waltz is a three-term GOP congressman from Florida, who also served multiple tours in Afghanistan and worked in the Pentagon as a policy adviser when Donald Rumsfeld and Robert Gates were defense chiefs.

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

Marco Rubio, secretary of state

Donald Trump is expected to nominate Sen. Marco Rubio of Florida as Secretary of State, FOX 13 Tampa reported citing multiple published reports.

The New York Times first reported the possible pick on Monday evening, with a source later telling FOX News that Trump plans to offer Rubio the job.

So far, Trump's team has not made an official announcement, but several Republican colleagues, including fellow Sen. Rick Scott has publicly congratulated Rubio.

Pennsylvania Sen. John Fetterman (D) called Rubio a "strong choice" in a post on X, and said he plans to vote for his confirmation.

"Unsurprisingly, the other team’s pick will have political differences than my own," he wrote. "That being said, [Rubio] is a strong choice and I look forward to voting for his confirmation."

Rubio is a three-term U.S. Senator who has served in Congress since 2011 and would become the first Latino to serve as Secretary of State if he assumes the position.

The senator was also a GOP rival to Trump in the 2016 presidential primary before dropping out of the race and endorsing Trump.

Tom Homan, ‘border czar’

Tom Homan was selected as Donald Trump’s "border czar" and will be tasked with conducting the largest deportation operation in U.S. history.

The 62-year-old served under Trump in his first administration leading U.S. Immigration and Customs Enforcement, was expected to be offered a position related to the border, an issue Trump made a hallmark to his campaign.

South Dakota Gov. Kristi Noem reportedly has been selected by Donald Trump for the role of secretary of the Department of Homeland Security, CNN and FOX News reported Tuesday. Trump has not made an official announcement.

Noem is a long-time Trump supporter who was considered a contender for vice president.

She will be tasked with overseeing a department that oversees everything from US Customs and Border Protection and Immigration and Customs Enforcement to the Federal Emergency Management Agency and the US Secret Service.

Elise Stefanik, United Nations ambassador

Elise Stefanik is a representative from New York and one of Donald Trump's biggest defenders going back to his first impeachment.

Stefanik was elected to the House in 2014 and was later 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, also 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 elevating her national profile.

The AP reports that if Stefanik is confirmed, she would represent American interests at the U.N. as Trump pledges to end the war started by Russia against Ukraine that began in 2022.

Trump has also called for peace as Israel continues its offensive against Hamas in Gaza and its invasion of Lebanon to target Hezbollah.

Stephen Miller, deputy chief of staff for policy

Stephen Miller was a vocal spokesperson during the presidential campaign for Donald Trump's priority of mass deportations. The 39-year-old was a senior adviser during Trump's first administration.

The AP reports that Miller has been a key figure in some of Trump's policy decisions, including 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.

Since Trump left office in 2021, Miller has served as the president of America First Legal, an organization made up of former Trump advisers tasked with challenging the Biden administration, media companies, universities and others over issues such as free speech and national security, the AP noted.

Lee Zeldin, Environmental Protection Agency

Former New York Rep. Lee Zeldin was picked by Donald Trump to lead the Environmental Protection Agency.

Zeldin is a longtime supporter of Trump and does not appear to have any experience in environmental issues, the AP reported.

The 44-year-old former U.S. House member from New York wrote on X, formerly Twitter, "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," Zeldin added.

Citing a statement, the AP noted Trump said Zeldin "will ensure fair and swift deregulatory decisions that will be enacted in a way to unleash the power of American businesses, while at the same time maintaining the highest environmental standards, including the cleanest air and water on the planet."
