Mike Pompeo

The US Secretary of State caught up in the Ukraine impeachment scandal.Mike Pompeo has a lot on his plate. He’s at the centre of the impeachment investigation into US President Donald Trump, who’s accused of breaking the law by pressuring Ukraine's president to dig up damaging information on a political rival. He’s pressuring the UK government to look again at its decision to give Chinese company Huawei a role in its 5G mobile phone network. And he’s facing criticism for refusing an extradition request relating to the death of British teenager Harry Dunn. In the week Mike Pompeo visits both the UK and Ukraine, Edward Stourton investigates the life and record of America’s top diplomat.Producers: Simon Maybin & Diane Richardson Editor: Penny Murphy
