President-elect Donald Trump appoints cabinet members and adds other key positions to his administration.

Members of this team will have a direct impact on the implementation of Trump’s policies during his second term.

President-elect Donald Trump is expected to announce plans to nominate Sen. Marco Rubio, R-Fla., for secretary of state, according to multiple sources familiar with the matter. ABC News reported Monday evening.

Rubio, 53, has been a member of the Senate since 2011. He is currently vice chairman of the Senate Select Committee on Foreign Intelligence and also serves on the House Foreign Relations Committee.

Several longtime State Department officials told ABC News they respected Rubio’s extensive foreign policy experience and considered it unlikely he would over-politicize the role. of Secretary of State.

Rubio was also reportedly favored for the role by Susie Wiles, Trump’s chief of staff and veteran Florida political activist, which could help lawmakers weed out loyalists from the first Trump administration, like the former acting director of national intelligence Richard Grenell and former National Security Advisor Robert. O’Brien.

Here’s a look at the president-elect’s other 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 Mike Waltz

Trump has tapped Rep. Mike Waltz, Republican of Florida, to be his national security adviser, multiple sources said.

Representative Lee Zeldin

President-elect Trump selected former Rep. Lee Zeldin as EPA administrator, the second New Yorker to be selected to the cabinet.

Zeldin, who left Congress in 2023, was a surprising choice for the role. His public appearances, both in his own campaigns and on behalf of Trump, have often found him speaking on issues including the military, national security, anti-Semitism, US-Israeli relations, immigration and crime.

He was among the congressional Republicans who voted against certifying the 2020 election results. In Congress, he did not serve on committees overseeing environmental policy.

In 2016, he pushed to change the designation of about 150 square miles of federal waters in Long Island Sound to state jurisdiction for New York and Rhode Island. He wanted to open the area to striped bass fishing, which is allowed in state waters but prohibited in the federal zone.

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.
