President Bill Clinton, the Mafia, the Unabomber, the 1993 World Trade Centre terror attack and the Oklahoma City bombing.

These are just a few of the investigations run by former FBI Director Louis Freeh across an incredible life and career.

Mr Freeh started as an FBI agent, before becoming a prosecutor and then being appointed as a Federal Judge by President George Bush Senior.

In 1993 he resigned after answering a call from President Bill Clinton and becoming just the fifth Director of the FBI.

In an extremely rare interview, he speaks with Ray Hadley about some of the incredible investigations he ran.

He tells Ray his time in office began tumultuously, with his three-year-old son lying to the President in the Oval Office at his appointment ceremony.

And it only went downhill from there. Mr Freeh’s first case was a criminal investigation into the man who hired him, President Bill Clinton.

“It was a very awkward situation. I had not unpacked my boxes.

“That of course changed the relationship indefinitely.”
