President Trump announced on Tuesday that he had ousted Secretary of State Rex W. Tillerson and will replace him with Mike Pompeo, now the C.I.A. director, ending the 14-month tenure of the nation’s chief diplomat who repeatedly had found himself at odds with the White House on a variety of key foreign policy issues.
“We were not really thinking the same,” Mr. Trump told reporters at the White House, explaining his decision to replace Mr. Tillerson.
He added: “Really, it was a different mind-set, a different thinking.”
Mr. Tillerson found out he had been fired before dawn, shortly after his flight returned from a weeklong trip to Africa, said Steve Goldstein, the under secretary of state for public diplomacy. There was no indication during the five-nation visit that Mr. Tillerson’s departure was imminent; Mr. Goldstein said on Tuesday morning that the secretary had been expected to remain in office for the foreseeable future.
The president did not personally call Mr. Tillerson, and Mr. Goldstein said he did not know how the chief diplomat learned he had been fired.
Mr. Trump announced his decision on Twitter.
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!

The move caught even the White House staff by surprise. Just the day before, a White House spokesman berated a reporter for suggesting there was any kind of split between Mr. Tillerson and the White House because of disparate comments on Russian responsibility for a poison attack in Britain.
