Outgoing Secretary of State Rex Tillerson said in a press conference on Tuesday that he "received a call today from the President of the United States a little after noon time." Trump tweeted about Tillerson's dismissal at 8:44am. In closing, Tillerson said he thanked the "300 plus million Americans...for your devotion to a free and open society, to acts of kindness toward one another, to honesty." He took no questions.
Catch up quick: Trump tweeted Tuesday morning that CIA Director Mike Pompeo would replace Tillerson. The State Department issued a statement shortly after that said Tillerson was unaware of the reason he was fired. Trump said he made the decision by himself.
