President-elect Donald Trump is starting to fill key posts in his second administration, putting an emphasis so far on aides and allies who were his strongest backers during the 2024 campaign.

Here's a look at who he's selected so far:

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

Susie Wiles, chief of staff

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

Wiles has a background in Florida politics. She helped 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 the president-elect. Wiles is said to have earned Trump's trust in part by guiding what was the most disciplined of Trump's three presidential campaigns.

Homan, who served under Trump in his first administration leading US Immigration and Customs Enforcement, was widely expected to be offered a position related to the border, an issue Trump made central to his campaign.

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

Homan, who served under Trump in his first administration leading US Immigration and Customs Enforcement, was widely expected to be offered a position related to the border, an issue Trump made central to his campaign.

Though Homan has insisted such a massive undertaking would be humane, he has long been a loyal supporter of Trump's policy proposals, suggesting at a July conference in Washington that he would be willing to "run the biggest deportation operation this country's ever seen."

Stefanik, 40, has served in that role ever since as the third-ranking member of House leadership.

Stefanik is a 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.

Stefanik, 40, has served in that role ever since as the third-ranking member of House leadership.

If confirmed, she would represent American interests at the UN as Trump vows to end the Ukraine war. She has also called for peace as Israel continues its onslaught in occupied Gaza and Lebanon.

Since Trump left office in 2021, Miller has served as the president of America First Legal, an organisation made up of former Trump advisers aimed at challenging the Biden administration.

Stephen Miller, deputy chief of staff for policy

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.

Trump argued throughout the campaign that the nation's economic, national security and social priorities could be met by deporting people who are irregular immigrants in the US.

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

Trump said Zeldin "will ensure fair and swift deregulatory decisions that will be enacted in a way to unleash the power of American businesses."

Trump has chosen former New York Rep. Lee Zeldin to serve as his pick to lead the Environmental Protective Agency.

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 US House member from New York wrote on X, "We will restore US energy dominance, revitalise 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.

In a statement, 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."
