President-elect Donald Trump appoints the members of the cabinet of his administration.

Cabinet appointees will have a direct impact on the implementation of Trump’s policies during his second term.

Here’s a look at the president-elect’s appointees so far.

Susie Wiles

Trump’s new chief of staff at the White House, Susie Wiles, veteran Florida political strategistis moving from a largely behind-the-scenes role as campaign co-chairman to the high-level position of the president’s closest adviser and lawyer.

A chief of staff is the president’s confidant, helping to execute an agenda and balance competing policy and policy priorities. They also tend to serve as gatekeepers, helping determine who the president spends his time with and who he speaks to — an effort that has angered Trump in the White House.

The daughter of NFL player and sportscaster Pat Summerall, Wiles worked in the Washington office of New York Representative Jack Kemp in the 1970s. He later served on Ronald Reagan’s campaign and in the White House as a planner.

Wiles then went to Florida, where she advised two Jacksonville mayors and worked for Rep. Tillie Fowler. After that, there were statewide campaigns in tough Florida politics, with Wiles credited with helping businessman Rick Scott win the governorship.

After briefly managing Utah Gov. Jon Huntsman’s 2012 presidential campaign, she led Trump’s effort in Florida in 2016, when his victory in the state helped him clinch the White House.

Two years later, Wiles helped elect Ron DeSantis as governor of Florida. But the two would develop a rift that ultimately led DeSantis to urge Trump’s 2020 campaign to cut ties with the strategist, as she once again ran the then-president’s state campaign.

Wiles ultimately managed Trump’s primary campaign against DeSantis and defeated the Florida governor.

Joining Trump’s third campaign in its early days, Wiles is one of the few senior officials to survive an entire Trump campaign and was part of the team that put together a much more professional operation for his third bid for office. White House – even if the first In any case, the president regularly broke these guardrails.

She largely avoided the spotlight, even refusing to take the microphone to speak as Trump celebrated his victory early Wednesday morning.

During his first administration, Trump experienced four chiefs of staff — including one who served in an acting role for a year — during a period of record staff disengagement.

Stephen Miller

Trump has named Stephen Miller, a longtime adviser and immigration hardliner, as his new administration’s deputy policy chief.

Miller is one of Trump’s longest-serving aides, dating back to his first campaign for the White House. He served as a senior advisor during Trump’s first term and played a central role in many of his policy decisions, notably on immigration, including Trump’s decision to separate thousands of immigrant families as a program deterrence in 2018.

Miller also helped craft many of Trump’s tough talk and was often the public face of those policies during Trump’s first term and during his campaigns.

Since leaving the White House, Miller has served as president of America First Legal, an organization of former Trump advisers designed as a conservative version of the American Civil Liberties Union, challenging the Biden administration, corporate media, universities and others on issues such as freedom of expression and religion and national security.

He was also a frequent presence during Trump’s campaign this year, traveling on his plane and often speaking in front of Trump during pre-shows at his rallies.

Tom Homan

Former Immigration and Customs Enforcement Director Tom Homan will be the Trump administration’s “border czar,” Trump announced on Truth Social.

Homan, a staunch Trump supporter, will be in charge of mass deportations promised by Trump throughout his 2024 campaign.

“I have known Tom for a long time, and there is no one better to keep order and control our borders,” Trump wrote in his message Sunday evening.

“Likewise, Tom Homan will be in charge of all deportations of illegal aliens to their home countries. Congratulations to Tom. I have no doubt that he will do a fantastic and long-awaited job,” Trump added.

Homan oversaw ICE during the Trump administration’s “zero tolerance” enforcement of separating parents from their children at the border.

The American Civil Liberties Union (ACLU) estimates that between 500 and 1,000 families have not been reunited.

Representative Elise Stefanik

President-elect Donald Trump has chosen Rep. Elise Stefanik to be U.S. ambassador to the United Nations, multiple Trump officials confirmed to ABC News.

Republican Rep. Stefanik was re-elected last Tuesday to a seat in the U.S. House of Representatives, representing New York.

Stefanik has built a national reputation as a steadfast ally of President-elect Trump and a sharp partisan critic.

First elected to Congress in 2014 at the age of 30, she eventually shed her reputation as a moderate Republican and became the highest-ranking woman in House Republican leadership.

Stefanik represents a largely rural district in upstate New York that includes some of the state’s least populated areas.
