George and Amal Clooney have talked about why they decided to welcome a Yazidi refugee into their home.

In a rare joint interview given to David Letterman over FaceTime for his Netflix show, My Next Guest Needs No Introduction, the couple talked about how they first met Hazim Avdal, who now lives at their property in Kentucky, near George's parents.

“I’ve had the privilege of representing a number of Yazidis who have been the victims of genocide perpetrated by ISIS over the past couple of years, that’s how I met Hazim,” said Amal. “And when I met him, I remember being so struck by his courage but also just his amazing spirit and how he spoke about, even after everything he lost, he spoke about his desire for justice, not revenge.”
