Trump appoints UN ambassador Elise Stefanik and border tsar Tom Homan

US President-elect Donald Trump has made two more key appointments ahead of his return to the White House in January.

Tom Homan, 62, will serve as Trump’s “border tsar”, having previously served as the returning president’s acting director of Immigration and Customs Enforcement (Ice).

New York Congresswoman Elise Stefanik, 40, has also been made ambassador to the United Nations, the BBC’s US partner CBS News has confirmed.

Meanwhile, Trump’s Republican Party are edging closer to full control of the US Congress. They already have a majority in the Senate and need to win just a handful of seats to take the House of Representatives.

A party needs 218 seats to win a House majority. The Republicans have 215 compared to the rival Democrats’ 210, according to CBS.

Control of the House gives a party the power to initiate spending legislation and launch impeachment proceedings against officials.

A majority in the House, the lower chamber of Congress, alongside the Senate, the upper chamber, would give Trump a greater chance of getting his plans approved than if Democrats controlled one or both.

In the meantime, attention has switched to who Trump appoints to serve in his administration.

In a post on his Truth Social platform, Trump said Homan would be “in charge of our Nation’s Borders (“The Border Czar”), including, but not limited to, the Southern Border, the Northern Border, all Maritime, and Aviation Security”.

He continued: “Likewise, Tom Homan will be in charge of all Deportation of Illegal Aliens back to their Country of Origin. Congratulations to Tom. I have no doubt he will do a fantastic, and long awaited for, job.”

One of Trump’s major campaign pledges was to deport immigrants who are in the US illegally.

A senior source close to Trump’s transition told CBS News that Trump had picked Stefanik for ambassador to the UN, and Stefanik accepted the role.

“I am honoured to nominate Chairwoman Elise Stefanik to serve in my Cabinet as US Ambassador to the United Nations,” Trump said shortly after in a statement to CBS News. “Elise is an incredibly strong, tough, and smart America First fighter.”

She confirmed her acceptance of the role to the New York Post, saying she was “truly honoured”.

“During my conversation with President Trump, I shared how deeply humbled I am to accept his nomination and that I look forward to earning the support of my colleagues in the United States Senate,” she said.

Trump earlier appointed Susie Wiles as his chief of staff. In his election victory speech, Trump called her “the ice maiden” – a reference to her composure.

Other names in the running to join the administration are billionaire X owner Elon Musk, who played a key role in Trump’s campaign, and Robert F Kennedy Jr – who ran his own presidential campaign before endorsing Trump.

There is speculation that Florida Senator Rick Scott could be in line to become Senate majority leader, having received the backing of Musk and others.

Trump has said Nikki Haley and Mike Pompeo – who both served in his first administration – will not be offered new positions.

A president-elect has responsibility for about 4,000 political appointments. During his first presidency, it took Trump months to assemble his cabinet.

Some of the appointments – including the UN ambassador job – require the approval of the US Senate. However, Trump has demanded that the next Senate leader let him make appointments without traditional confirmation votes.

Trump has confirmed that Homan will have a wide-ranging role overseeing border security and deportation policy – two of his main campaign issues.

Homan, a former police officer, also played an important role in Trump’s first presidency as the acting director of Immigration and Customs Enforcement (Ice).

He resigned in 2018 but remained a proponent of Trump’s hard-line approach. He supported separating migrant children from their parents as a means to deter illegal crossings, and has said politicians who support migrant sanctuary policies should be charged with crimes.

Homan is a visiting fellow at the Heritage Foundation – a conservative think-tank that published the Project 2025 document, which set out a “wish list” for a second Trump presidency. Trump has distanced himself from the organisation.

Stefanik became the youngest woman ever elected to Congress in 2014, then aged 30. She continues to represent New York’s 21st District.

After entering politics, the fourth-ranking House Republican initially positioned herself as a moderate and criticised Trump – but later became his loyal defender.

In his statement to the New York Post, Trump described her as “an incredibly strong, tough, and smart America First fighter”.

The UN ambassador role is crucial to global cooperation and security, and Stefanik’s nomination comes as conflicts continue to rage in Ukraine and the Middle East.
