President-elect Donald Trump has offered Republican Representative Elise Stefanik the job as US ambassador to the United Nations, CNN reported on Sunday, citing two unnamed sources.

Reuters earlier reported that Stefanik, a fierce Trump ally, was under consideration for the role.

"President-Elect Trump will begin making decisions on who will serve in his second Administration soon. Those decisions will be announced when they are made," Karoline Leavitt, a spokeswoman for Trump-Vance team said in an emailed statement, without confirming or denying the CNN report.

Stefanik could not be immediately reached.

Trump said on Saturday that former Republican presidential contender Nikki Haley and former Secretary of State Mike Pompeo will not be asked to join his administration.

Haley served as the US ambassador to the United Nations under Trump during his previous term and had endorsed Trump for president despite having criticized him harshly when she ran against him in the party primaries.

US 'border czar'

Also on Sunday, Trump said that Tom Homan, the former acting director of Immigration and Customs Enforcement (ICE), will be in charge of the country's borders in his new administration.

Homan will 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," Trump said in a post on his Truth Social platform.

Homan, who served in Trump administration for a year and a half during his first term, is also a contender for secretary of homeland security.

Trump made cracking down on illegal immigration the central element of his campaign, promising mass deportations. He frequently praised Homan during the campaign, and Homan often hit the trail to rally supporters.

Trump added in his Truth Social post that Homan will be in charge of the deportation of illegal immigrants.
