How the media is grappling with the Trump phenomenon
Hardtalk is celebrating 20 years on air and to mark the occasion presenters: Stephen Sackur, Sarah Montague and Zeinab Badawi join the programme's first anchor Tim Sebastian.
They discuss how US President Donald Trump's election campaign has changed politics forever through the use of social media.
Hardtalk interviewed Mr Trump in 1998 when he spoke about revenge and getting even with those who had hurt him.
You can see the interview in full on Monday 10 April on BBC World News and the BBC News Channel and after on BBC iPlayer (UK only)
