Rex Tillerson, the Texas oil man who has served as President Trump’s secretary of state since February 2017, has been fired. “Thank you to Rex Tillerson for his service," Trump tweeted Tuesday morning. Deputy Secretary of State John Sullivan will handle the transition to Tillerson's replacement, current CIA Director Mike Pompeo. Gina Haspel has been appointed to replace Pompeo, and if confirmed, will be the first woman to serve in the role. She has worked for the CIA for 33 years.
