The US President tweeted: “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!”
Speaking to reporters after the news emerged, Trump thanked Mr Tillerson, telling reporters: “I very much appreciate his commitment and his service and I wish him well.”
He admitted they “disagreed on things” and said he shares a more similar way of thinking with Tillerson’s successor, Mr Pompeo.
A White House official told Reuters Mr Tillerson was removed from his post so the President could install a new team ahead of talks with North Korea planned for May.
Mr Tillerson has not yet reacted to the news but is due to address the media shortly.
