Trump told reporters he made the decision himself, citing disagreements with Tillerson that included North Korea diplomacy, steel and aluminum tariffs, and the Iran nuclear agreement.
…Trump’s tweet Tuesday came the day after Tillerson blamed Russia for an assassination of an ex-spy in London — something the White House had specifically declined to do just hours before.
…The State Department said Tillerson did not speak to Trump himself — something White House officials confirm — and that the secretary didn’t know about the final decision until the tweet.
…A State Department official sent out a terse reaction to the sudden news.
Steve Goldstein, undersecretary for public diplomacy, said Tillerson “did not speak to the President and is unaware of the reason” for the decision.
