On Profile this week, we look at the life and career of new US Secretary of State, Rex Tillerson.
He flew to Moscow this week to urge Russia to abandon its support for Syria's President Assad following the chemical weapons on a town in northern Syria earlier this month.
It seems he came away empty handed, with Donald Trump warning that relations between Russia and the US were now at "an all-time low".
So who is Rex Tillerson ?
Mark Coles gets to grips with Tillerson's past : his formative years in the Scouts, his time as a drummer at university, the four decades spent at oil and gas giant ExxonMobil where he ended up as CEO and his controversial business ties with Russia which now hang over his new role as America's top diplomat.
