Tillerson, one White House official said, “had not learned his lesson from the last time,” when Trump publicly rebuked his top diplomat on Twitter over the wisdom of talking to North Korea.
A senior U.S. official said foreign diplomats and leaders often ask if Tillerson is speaking for the administration and when he will depart. Another White House aide said White House officials, diplomats and other Cabinet secretaries largely deem the former ExxonMobil chief executive “irrelevant.”
Inside the White House, this person said, there are fairly regular conversations about who will replace Tillerson even as he remains in the job. CIA Director Mike Pompeo, for example, may no longer be the leading choice because it means he would not brief Trump every day, and the president likes him in that role, the official said.
