Donald Trump his sacked his top diplomat ahead of proposed talks with North Korea.
US President Donald Trump sacked Secretary of State Rex Tillerson on Tuesday and named current CIA chief Mike Pompeo to succeed him, ending a rocky tenure by the Texas oilman who had frequently been at odds with the mercurial US president.
A senior White House official said Mr Trump wanted to reshuffle his team with a view to launching talks with North Korea, following last week's spectacular announcement he plans to meet Kim Jong Un.
The outgoing secretary of state, who returned overnight from a trip to Africa, did not speak to the president before his sacking was announced and was unaware of the reason for his sudden downfall, according to a top aide.
Mr Trump thanked Mr Tillerson "for his service," but had scant words of praise for the 65-year-old Texan, who had effectively been sidelined on the world stage and was long rumored to be on the way out.
We got along actually quite well but we disagreed on things.

Before leaving on a trip to California, Mr Trump spoke openly of his divergences with the former Exxon chief, including over the Iran nuclear deal, as he explained the rationale for the latest departure from his chaotic White House.
"We got along actually quite well but we disagreed on things," Mr Trump told reporters.
"When you look at the Iran deal, I thought it was terrible, he thought it was okay," Mr Trump said. "So we were not really thinking the same."
"I wish Rex a lot of good things," the president added. "I think he's going to be very happy. I think Rex will be much happier now."
Later at the State Department, a visibly emotional Mr Tillerson said Mr Trump called him around noon from Air Force One and that he had also spoken with White House Chief of Staff John Kelly.
He said his tenure ends on March 31 but he would delegate his responsibilities to John Sullivan, deputy secretary of state, at the end of Tuesday.
“What is most important is to ensure an orderly and smooth transition during a time that the country continues to face significant policy and national security challenges,” Mr Tillerson, whose voice quivered at times, told reporters in a packed briefing room.
Mr Tillerson had developed a strong relationship with Secretary of Defense Jim Mattis, and the two were seen as a moderating influence on some of Mr Trump’s policies.
“I’m told for the first time in most people’s memory the Department of State and the Department of Defense have a close working relationship where we all agree the US leadership starts with diplomacy,” he said.
Praise for Pompeo
Announcing Mr Tillerson's sacking in a tweet earlier Tuesday, Mr Trump lavished praise on Pompeo, a former US army officer and congressman who led the CIA for nearly 14 months, saying he would do a "fantastic job!"
"He will continue our program of restoring America's standing in the world, strengthening our alliances, confronting our adversaries, and seeking the denuclearization of the Korean Peninsula," Mr Trump added, calling him "the right person for the job at this critical juncture" and urging his swift confirmation.
His enthusiasm was echoed by the US envoy to the United Nations, Nikky Haley, who tweeted her congratulations to her "friend" Pompeo.
To succeed Pompeo at the Central Intelligence Agency, Mr Trump nominated Gina Haspel, a controversial career intelligence officer who would become the first woman tapped for the post.
Ms Haspel has been reported to have overseen a CIA "black site" in Thailand where Al-Qaeda suspect Abu Zubaydah was waterboarded after the 9/11 attacks.
'Every intention of remaining'
Mr Tillerson had a tumultuous tenure at the State Department.
He was repeatedly forced to deny he had fallen out with Mr Trump, vowing to remain in the post despite a sensational report that he once dubbed the president a "moron."
A respected figure in the oil business, his tenure drew scorn from Mr Trump's opponents, from former diplomats and from the Washington policy elite.
During his time in the post, he was faced with an extraordinary array of foreign policy challenges, from North Korean nuclear threats to Russian subversion to attacks on US diplomats in Cuba.
But his efforts were often overshadowed by Mr Trump's un-diplomatic style and his streams of taunting tweets stirring international tensions.
Mr Tillerson was thousands of miles away on a tour of African countries when Mr Trump made the snap decision to meet Kim, and suspended his schedule on grounds he was "unwell" before cutting short his trip.
In a cruel twist of fate, one of Mr Trump's most public clashes with Tillerson came last October when the president tweeted that his top diplomat was "wasting his time" pursuing contacts with North Korea.
Undersecretary of State Steve Goldstein, in a statement, made clear Mr Tillerson was caught off guard.
"The secretary had every intention of remaining because of the tangible progress made on critical national security issues. He established and enjoyed relationships with his counterparts," Mr Goldstein said.
"We wish Secretary-Designate Pompeo well," he added.
Shortly thereafter, Mr Goldstein himself was fired.
