President Donald Trump will nominate State Department spokeswoman, Heather Nauert, as USA ambassador to the United Nations, two White House officials have said.
A representative of the State Department did not immediately respond to a request for comment.
Ms Nauert is known to be personally close to both Ivanka Trump and her husband, Jared Kushner, who are both White House advisors.
Nauert also now serves as the acting Under Secretary for Public Diplomacy and Public Affairs at the State Department. Trump is expected to announce the nomination on Friday.
Heather Nauert, a former anchor and correspondent at Fox News Channel, joined the State Department as spokeswoman in April 2017.
He added: "She's excellent, she's been with us a long time, she's been a supporter for a long time, really - excellent".
Trump told reporters in November that Nauert, who does not have any prior political or policy-making experience, was "under very serious consideration" for the position.
While Nauert struggled during the tenure of former Secretary of State Rex Tillerson - so ostracized from his inner circle that she considered quitting - she could now bring to the United Nations close ties to the White House and a good working relationship with Secretary of State Mike Pompeo.
If confirmed, Nauert, 48, would succeed Nikki Haley, who said in October she would be leaving the United Nations post at the end of the year.
He pulled the United States out of the U.N. human rights body in September, citing bias toward Israel, and his administration has cut funding for the U.N. refugee agency and a year ago proposed usa funding cuts for aid and diplomacy that could curb the work of the global body.
Having the direct support of the president and Secretary of State, Mike Pompeo, could buttress her image, however, among global diplomats at the United Nations, who have bristled at Donald Trump's "America First" foreign policy. She will have to be confirmed by the Senate to become ambassador to the United Nations. But she has said she would not be running for the top job in 2020, when Trump plans to run for a second term.
Nuart was brought on to the administration after providing commentary on "Fox and Friends" on what appears to be Trump's favorite cable news network.
White House press secretary Sarah Huckabee Sanders described Nauert in March as "a team player" and "a strong asset for the administration".
