WASHINGTON —Rex Tillerson is out as secretary of state. President Donald Trump tweeted Tuesday morning that he’s naming CIA director Mike Pompeo to replace Tillerson.

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!

Pompeo is to be replaced at CIA by Gina Haspel, Pompeo’s deputy at CIA. She would be the first woman in that role.

Tillerson had just returned from a shortened trip to Africa hours before Trump’s announcement. Trump offered no explanation for the change.

Pompeo was elected to the 4th District congressional seat in Kansas during the tea party wave of 2010. He is now fourth in line of presidential succession behind the vice president, speaker of the house and president pro tempore of the senate.
