With no policymaking or negotiating experience, and after 20 months as a spokeswoman for the state department, Nauert will take her seat on the security council alongside counterparts with decades of experience.
Under Pompeo, whose foreign policy views more closely align with Trump's than Tillerson's, Nauert became part of the inner circle.
She would replace Nikki Haley, who announced that she was resigning in October.
He noted that Nauert has worked at the State Department for almost two years, and she has been involved in key meetings and discussions, including working very closely with Secretary of State Mike Pompeo. She would replace Nikki Haley, who was twice elected governor of SC but also lacked foreign policy experience.More news: U.S. must stay in Afghanistan or face new 9/11, top general urges
A Columbia journalism school graduate and former ABC reporter, Ms. Nauert had two stints at Fox News, the first of which started in 1998 as a reporter.
Nauert has served as the State Department's spokeswoman since April 2017 - and it reportedly wasn't all happy times. The role of ambassador to the United Nations does not always have Cabinet level.
Nauert's relationship with Spencer dates back to 2009, when she hosted him and fellow anti-Muslim activists Frank Gaffney, Tarek Fatah and Nonie Darwish to discuss an hour-long segment on "stealth jihad".
If Ms Nauert passes the Senate confirmation and subsequently assumes the role, her top priority will be to maintain sanctions on North Korea, which her predecessor managed to rally global support for a year ago when Kim Jong-Un was conducting his ballistic missile testing.

Maybe the new ambassador will eventually become a rock star beyond the ranks of Fox News viewers and enhance her own power, so long as she doesn't undercut the ultimate Boss.
Although some have speculated that Haley may challenge Trump in the 2020 presidential election, Haley has said that she will support the president. However, she quickly learned key issues and how the United Nations operates.
But Bruen, who now heads the Global Situation Room consulting firm, questioned whether Nauert was the best pick when "American influence on the world stage is at a historic low".
"With Pompeo more firmly in control and Bolton focused on his anti-multilateral agenda, there's a sense the USA ambassador will have less clout", Gowan said.More news: XFL Officially Announces Franchise Cities & Venues
