Earlier this month the US Secretary of State Marco Rubio was also made President Trump's National Security Advisor. The last person to undertake both roles simultaneously was Henry Kissinger in the 1970s. The son of Cuban immigrants, Mr Rubio has had a turbo-charged career; rising from junior positions in his home city of Miami, to the US Senate which he reached before he turned 40 and now a Cabinet position where he dominate US foreign policy.

As a boy he dreamed of being President and he made his first attempt in 2016. The Republican primaries were brutal, with candidates trading deeply personal insults. It was assumed that Mr Rubio's relationship with the eventual winner of that contest - Donald Trump - had been fatally damaged. But they continued their working relationship and today Rubio serves as one of the President's most trusted advisors.

Will Marco Rubio be tempted to run once again for the White House? And what forces have shaped his stellar political career?
