In her first speech as ambassador, she warned that there would be consequences against those nations that worked against the will of the U.S.at the global organization.
President Donald Trump plans to nominate State Department spokeswoman Heather Nauert as the next U.S. ambassador to the United Nations, a senior administration official said Thursday.
Trump is expected to tweet the announcement Friday morning, according to Fox News.
Nauert will be replacing Nikki Haley who announced that she will be retiring at the end of the year, saying that she wanted to "take a little time off" after her two terms in office. If Nauert is confirmed by the Senate, she would be a leading administration voice on Trump's foreign policy.
"She's excellent. She's been with us a long time", Trump said of Nauert last month.
Nauert and the State Department did not immediately respond to requests for comment.
Trump expected to pick State spokeswoman for UN ambassador
Nauert joined the State Department previous year after a career as a television anchor and correspondent at Fox News.
While the senator acknowledged that Nauert does have State Department experience, he pointed out that "she has no experience as a diplomat", also arguing that she beings to the table "no meaningful experience in the government".
It was reported in November that Nauert had been offered the job, but it was not clear at the time whether she had accepted.
Ahead of the vote, the USA ambassador sent a letter to all UN missions to make clear that "the United States takes the outcome of this vote very seriously". She oversaw public diplomacy in Washington and all of the roughly 275 overseas USA embassies, consulates and other posts. She does not have prior political or policy-making experience.
Israeli leaders nonetheless thanked her and feted the results as proof of wide support for Israel's position. All the while, she stayed in the good graces of the White House, even as Tillerson was increasingly on the outs.
