Nauert is in talks to become the State Department spokeswoman, pending Secretary of State Rex Tillerson's approval, sources familiar with the discussions told Politico.
Nauert has been at Fox News since 1998, save for a two-year stint at ABC. She is currently an anchor on "Fox and Friends," the network's morning show, which has been praised by President Trump.
At a press conference Thursday, Trump said "Fox and Friends" is "the most honest morning show."
Trump has also drawn from the far-right Breitbart News to fill out his administration, including chief strategist Steve Bannon, who previously served as the website's executive chairman, and Sebastian Gorka, a former Breitbart national security editor who is now a deputy assistant to the president.
