President Donald Trump has fired Secretary of State Rex Tillerson, replacing him with CIA Director Mike Pompeo.
With Mr Pompeo moving, CIA Deputy Director Gina Haspel will take over the running of that department.
Mr Trump and Mr Tillerson have numerous reports about the breakdown of their relationship in recent months, which have been denied by both the White House and the State Department. Mr Trump had suggested last week that more changes were coming at the White House, after economic advisor Gary Cohn resigned in the wake of disagreements with the president about his policy on trade tariffs. Mr Trump also lost his Communications Director Hope Hicks late last month after she resigned.
