In a statement, Mr Trump said: “I have gotten to know Mike very well over the past 14 months, and I am confident he is the right person for the job at this critical juncture.”
“He will continue our program of restoring America’s standing in the world, strengthening our alliances, confronting our adversaries, and seeking the denuclearisation of the Korean Peninsula,” he added.
Mr Tillerson, a former chief executive of ExxonMobil, was appointed to the job just over a year ago.
Mr Pompeo issued a statement saying he was “looking forward” to representing the President.
“I am deeply grateful to President Trump for permitting me to serve as Director of the Central Intelligence Agency and for this opportunity to serve as Secretary of State.
“His leadership has made America safer and I look forward to representing him and the American people to the rest of the world to further America’s prosperity,” he said.
