Speculation has circulated for weeks that Secretary of State Rex Tillerson is on his way out. He has publicly contradicted, and been contradicted by, his boss the president. He reportedly called President Trump a "moron" in a private meeting, and never denied that when asked by reporters.
Tillerson, 65, the former chief of ExxonMobil, has repeatedly said he has no plans to step down, while adding that he serves at the president's pleasure.
But tension between Foggy Bottom and the White House has not subsided. Thursday, the speculation kicked up again when the New York Times reported the White House had drawn up a plan for CIA director Mike Pompeo to replace Tillerson.
