Tillerson axed as US secretary of state

US President Donald Trump has fired Secretary of State Rex Tillerson and announced he will nominate CIA Director Mike Pompeo to replace him.

The firebrand leader ends Tillerson's difficult tenure by tweeting an ouster that had been long expected and yet was shocking in its abruptness.

"We disagreed on things," Trump said moments later, a diplomatic version of a difficult relationship with his top diplomat that included reports that Tillerson had called the president a moron in meetings with other officials.

Speculation that Tillerson would be fired grew with those reports last fall, and the secretary of state never personally denied their accuracy.

It spiked again in November when White House officials told multiple news outlets of a plan to replace him with Pompeo. But Tillerson continued to hang on, pointing out that his doubters had yet to be proven right.

Trump's change puts an ardent foe of the Iran nuclear deal in charge of US diplomacy as the president also dives into high-stakes talks with North Korea.

Trump mentioned differences over how to handle the Iran agreement, which he wanted to withdraw from: "So we were not really thinking the same."

Though Trump and other officials said he'd been considering replacing Tillerson for some time, the president said he made the decision only recently and "by myself."

Tillerson will be "much happier now," Trump said.

The reshuffle comes at a time of intense turnover within Trump's administration that has alarmed those both in and out of the White House.

Top economic adviser Gary Cohn announced his resignation last week, not long after communications director Hope Hicks and staff secretary Rob Porter both departed near the start of Trump's second year in office.

For Trump, the shift comes at a critical time for several key foreign policy priorities, including a decision on whether to withdraw the US from the 2015 Iran deal that Pompeo has called "disastrous."

Tillerson had long pushed Trump to remain in the agreement and had been pursuing a delicate strategy with European allies and others to try to improve or augment it to Trump's liking.

It also comes amid a dramatic diplomatic opening with North Korea, with Trump set to hold a historic meeting with leader Kim Jong Un in May.

Pressuring North Korea with sanctions and other isolation measures had been a top Tillerson priority, and he had been one of the administration's more vocal advocates for holding talks in some form with the North. When Trump ultimately accepted Kim's invitation for a meeting, Tillerson was in Ethiopia, though he said he spoke with Trump about it shortly before it was announced.

The president said he was nominating the CIA's deputy director, Gina Haspel, to take over for Pompeo at the intelligence agency. If confirmed, Haspel would be the CIA's first female director

Pompeo, a former Republican congressman from Kansas, has already been confirmed by the Senate for his current role at the CIA, making it extremely likely that he will be confirmed for the State Department role. Trump tweeted, "He will do a fantastic job!"

As for his relationship with Tillerson, Trump said, "Really, it was a different mindset. It was a different thinking."
