President Trump fired Secretary of State Rex Tillerson on Tuesday morning in a tweet that followed a year of frequent tension between the two leaders.
Trump said he is nominating CIA director Mike Pompeo as Tillerson's replacement, which requires confirmation by the Senate.
"Rex and I have been talking about this for a long time ... we got along quite well but we disagreed on things," Trump told reporters at the White House. "We were not really thinking the same ... with Mike, we have a very similar thought process."
State Department officials, on the other hand, said they were caught off guard.
"The secretary had every intention of remaining because of the tangible progress made on critical national security issues," said Undersecretary of State Steve Goldstein. "He established and enjoyed relationships with his counterparts. He will miss his colleagues at the Department of State and enjoyed working together with the Department of Defense in an uncommonly robust relationship."
Continued Goldstein: "The secretary did not speak to the president this morning and is unaware of the reason, but he is grateful for the opportunity to serve, and still believes strongly that public service is a noble calling and not to be regretted. "
Trump and Tillerson have been described as talking often but sometimes also appeared quite out of step on major foreign policy decisions.
A White House official says the president wanted to have a new team in place in advance of upcoming talks with North Korea and ongoing trade negotiations.
Tillerson, who was traveling in Africa last week, was caught flat-footed when the surprise announcement came that Trump had accepted an invitation to meet with North Korean leader Kim Jong Un. Just a day earlier, he'd told reporters that negotiations were a long way off.
Trump has tapped Gina Haspel, Pompeo's former deputy and a CIA veteran, to take the helm of the spy agency.
Haspel did not require Senate confirmation to serve in her deputy role but will to serve as the full-fledged director of the agency. Her hearing could exhume many CIA demons about the torture of terror suspects and the secret detention program that followed the 2001 terror attack.
Democrats blasted what they called the nonstop chaos of the Trump White House, which they said meant it cannot focus on conducting business seriously.
"The instability of this administration in just about every area weakens America," said Senate Minority Leader Chuck Schumer, D-N.Y.
Tillerson, the former boss of petrogiant ExxonMobil, didn't know Trump before 2016 — and their relationship seemed to eventually rupture after months of disputes over policy, embarrassing leaks and a few public humiliations by the president himself.
Trump told reporters on Tuesday that he and Tillerson had always gotten along and that he was a "good man," but their friction over tough issues such as the Iran nuclear deal had been what compelled Trump to replace him.
Slow burn
The campaign had apparently been in the works for some time. White House officials on Nov. 30 cranked up the pressure on Tillerson with an apparent targeted leak to The New York Times. It revealed the existence of a secret plan by chief of staff John Kelly to force out Tillerson and replace him with Pompeo.
Trump would then nominate Sen. Tom Cotton, R-Ark., to replace Pompeo, according to the Times. As it happened, Cotton is not getting the nomination to lead the CIA, after all.
The report took care to say that the plan was "tentative" and Trump hadn't yet approved it, but the message to the State Department's headquarters in Foggy Bottom in Washington, D.C., was clear: the White House was finished with Tillerson and wanted him out.
That story followed other evidence that the relationship between the president and the nation's top diplomat was barely functional.
Tillerson earlier said he would not resign in October after an NBC News report said Tillerson had called Trump a "moron" in July after a tense meeting at the Pentagon. Tillerson declined to deny it publicly, and Trump retorted to Forbes magazine that he was ready to compare "I.Q." tests — "and I can tell you who's going to win."
Trump also undermined Tillerson's efforts to find a diplomatic solution to the situation in North Korea. As Tillerson kept up support for talks with Pyongyang over its nuclear and ballistic missile programs, Trump said on Twitter Oct. 1 that Tillerson was "wasting his time."
"Save your energy Rex, we'll do what has to be done!" Trump wrote.
It was about five months later that Trump agreed to meet with North Korean leader Kim Jong Un.
Tillerson had also distanced himself from what critics have called Trump's equivocation between neo-Nazis and counter-protesters, who clashed over a Confederate monument in Charlottesville, Va.
Tillerson appeared Aug. 27 on Fox News Sunday and was asked by host Chris Wallace about the way the international community views the United States following Trump's controversial comments about the protesters and counter-protesters in the wake of deadly violence in Charlottesville.
"We express America's values from the State Department," Tillerson said. And later: "The president speaks for himself, Chris."
Tillerson's departure makes him the latest member of Trump's inner circle in the administration to step down — following a series of White House aides, starting with national security adviser Mike Flynn, continuing on to chief strategist Steve Bannon, press secretary Sean Spicer, chief of staff Reince Priebus and chief economic adviser Gary Cohn — who have left their posts amid administration turbulence.
Tillerson's firing also follows the departure former Health and Human Services Secretary Tom Price, who was ousted over a travel expense scandal.
Tillerson leaves behind a State Department that critics have called a shadow of its former self because of Tillerson's disconnection from the department and the White House's antipathy toward appointing or keeping top talent in the nation's diplomatic ranks.
Some ambassadorships around the world and other top jobs at the department's Foggy Bottom headquarters remained vacant.
And speculation has swirled for so long that Tillerson might quit that this isn't the first wave of discussion about prospective replacements. A previous go-round centered on Nikki Haley, the U.S. ambassador to the U.N. and former governor of South Carolina. The New York Times reported there was tentative talk that President Trump might appoint his daughter, Ivanka, as Haley's replacement at the U.N.
For now, Haley remains in her post in New York and the Ivanka narrative appears to have cooled.
Tillerson's tenure as America's top diplomat was unlikely. Trump interviewed other, more conventional candidates, including 2012 GOP presidential nominee Mitt Romney, but he ultimately gave the nod to the Texas oilman Tillerson based on a recommendation from former Defense Secretary Robert Gates.
Tillerson told interviewers early on that he hadn't been looking for the job and was "stunned" to get Trump's offer — but his wife, Renda St. Clair, sold him.
"'I told you God's not through with you,' " as Tillerson recounted his wife's remarks.
Oilman
Tillerson had no governmental experience; he went to work in 1975 for Exxon Co., as it was then known, as an oil production engineer. But having risen to become CEO of the descendant ExxonMobil, he effectively served as a kind of head of state of his own — not only running the energy behemoth, but also conducting its foreign policy across the globe in all the places it drilled or refined or conducted other operations.
That work brought Tillerson into contact with all manner of leaders, including Russian President Vladimir Putin, who awarded him Russia's Order of Friendship in 2008. Trump and Tillerson met with Putin and Russian Foreign Minister Sergey Lavrov in Germany in June, and then Tillerson continued follow-up negotiations with Russia until his departure from office.
As secretary of state, Tillerson belonged to a cadre of leaders who sometimes preceded Trump on international travel to assuage allies' concerns about him. Or they returned after his visits to try to smooth things over.
Tillerson, Vice President Pence, Defense Secretary James Mattis and others emphasized conventional points about American commitment to allies, to international norms and other longstanding points — often after Trump appeared willing to flout them.
At the same time, Tillerson stayed in lockstep with the president on many matters of policy. He defended to the State Department press corps, for example, the realism that he said underpinned the administration's new strategy focused on Afghanistan, which amounted to the new goal of playing to a draw.
"I think the president was clear this entire effort is intended to put pressure on the Taliban to have the Taliban understand: You will not win a battlefield victory. We may not win one, but neither will you," he said.
