Jack Smith is no stranger to the courtroom. He counts mob bosses, public officials and war criminals among those he has put behind bars. But no case he has been involved with has been as high profile as the one he is bringing against the former, and possible future, President of the United States - Donald J. Trump.

In the last week, he made a very rare public appearance announcing his charges against Trump, unsurprisingly leading to a volley of criticism from the man he will face down in court.

A young man from upstate New York, made his way first to Harvard Law School and then, New York City, 250 miles away from his home town. Here he embarked on the impressive legal career that has led to his appointment as Special Counsel.

Mark Coles speaks to his old sports teacher and colleagues about his distinguished career so far and why he will not let anything get in his way of presenting the strongest possible case against President Trump.
