Before taking on the role of State Department spokeswoman, Nauert was employed as a Fox News anchor and correspondent.
U.S. President Donald Trump will nominate State Department spokeswoman Heather Nauert as U.S. ambassador to the United Nations, a source familiar with his decision said on Thursday, tapping someone with no prior policy or political experience to deal with some of the world's thorniest issues.
She became the State Department's spokeswoman in April 2017 and was named earlier this year as the acting undersecretary for public diplomacy and public affairs.
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.
After Haley announced that she'd be stepping down this past October, several outlets reported that Nauert was expected to be shortlisted for the role. But when White House officials told her they wanted her, she accepted.
The post is considered one of the highest profile positions in US diplomacy.
He pulled the United States out of the UN human rights body in September, citing bias towards Israel, and his administration has cut funding for the UN refugee agency and previous year proposed USA funding cuts for aid and diplomacy that could curb the work of the global body. President Donald Trump is expected to nominate Nauert to be the next US ambassador to the United Nations.
Just 18 months ago, she wasn't even in government. Haley also didn't have foreign policy experience when she took the United Nations posting, but she had twice been elected governor of SC.
One of the reports came from Fox News, where Ms Nauert has previously worked as a presenter.
Nevertheless, Nauert has gained Secretary of State Michael Pompeo's trust after being excluded from the inner circle of his predecessor, Rex Tillerson. She announced in October that she would leave the position by the end of the year.
The president picked Nauert after considering other potential nominees including former White House aide Dina Powell, ambassador to Canada Kelly Craft and ambassador to Germany Ric Grenell.
