Outgoing Secretary of State Rex Tillerson, whose firing was announced hours earlier, is slated to address reporters from the State Department briefing room on Tuesday afternoon.
Tillerson's ouster, first reported Tuesday morning, was quickly confirmed by President Donald Trump in a tweet.
Trump tweet: Mike Pompeo, Director of the CIA, will become our new Secretary of State. He will do a fantastic job! Thank you to Rex Tillerson for his service! Gina Haspel will become the new Director of the CIA, and the first woman so chosen. Congratulations to all!
White House officials said Tillerson found out on Friday that he would be fired, according to the Associated Press.
But in a statement on Tuesday, Undersecretary of State Steve Goldstein said, "The Secretary had every intention of staying because of the critical progress made in national security. He will miss his colleagues at the Department of State and the foreign ministers he has worked with throughout the world."
"The Secretary did not speak to the President and is unaware of the reason, but he is grateful for the opportunity to serve, and still believes strongly that public service is a noble calling," Goldstein said.
Shortly after making the statement, Goldstein was fired by the Trump administration for contradicting the White House's account of Tillerson's firing, NBC News reported.
Tillerson will be replaced by CIA Director Mike Pompeo; Deputy CIA Director Gina Haspel will take over for Pompeo, making her the first woman to run the spy agency.
