‘We disagreed on things’: A look back at Trump-Tillerson friction

US President Donald Trump has fired Secretary of State Rex Tillerson via Twitter, citing differences over key foreign policy issues.

The US President Donald Trump said on Tuesday that he dismissed Rex Tillerson as secretary of state at least in part over policy differences.

The two had disagreed over critical foreign policy issues, including the Iran nuclear deal.

Tillerson has repeatedly had to deny falling out with the president – including that he called him a “moron”. He is urging a smooth transition – after his dismissal by Trump, via Twitter.

The outgoing secretary of state will be replaced by CIA director, Mike Pompeo.
